Explanatory Notes
General information
All weights and measures shown on invoices will be governed by standards of
the respective specifications so offered.
Care has been taken to ensure that all data and information herein are factual
and that numerical values are accurate. To the best of our knowledge, all
information contained in this handbook is accurate at the time of publication.
Continental Steel Pte Ltd assumes no responsibility for errors in or
misinterpretation of the information contained in this handbook or in its use.
Introduction
To serve the increasing demands for more section types and to create the awareness
on the proper use of steel, we have come up with a new product catalogue. The new
handbook has a more comprehensive range of products and useful technical
information, and it also functions as a design reference for the consultants and a
product catalogue for our customers.
To help our customers to proper design and use of steel we have also extended the
business by offering our customers technical support from our team of Structural
Engineers.
The catalogue contains up-to-date materials standards specifications.
Note that new European standards supersede most of the old British Standards, see
sections “Materials” and “Manufacturing tolerances” under this chapter, and the design
guide BS 5950 substitutes BS 449.
The content list of our new catalogue shows that we have increased the range of
section types and sizes. This is to give our customers a bigger choice when selecting
material and more room for imagination, innovation and flexibility when designing and
planning for new structures.
With more sections to choose from, the designers will have opportunities to make
better and more cost efficient designs, by selecting the section size closest to that
required.
Some of the new section types we have added to our product list are:
Structural Tees
Hot Finished Ellipcon Sections, elliptical and semi elliptical
Super Hot Columns
Parallel Flange Channels
High-Tensile Galvanised C and Z Purlins.
The new catalogue also contains a comparison between hot finished and cold formed
hollow sections. We included this because substitution of cold formed sections for hot
finished sections are very common in this region, but not everybody knows the
differences between the two section types.
The first few pages of the catalogue give a short resume of the company profile and
the services we provide. The summary shows that we have extended our business by
adding more value to the steel we supply to our customers.
Our steel suppliers are mills with third party certifications, such as ISO, CARES and/or
Lloyd’s.

EXPLANATORY NOTES
7
In structural design and construction there are a lot of details to remember. For
example, when buying steel beams, columns, bars, plates and pipes, be sure to buy
the correct section type, size and grade. If the specified section is not available,
check with the designer before any changes to the structure are made.
For example, a parallel flange channel can not be substituted with a plain channel
without reference to the design engineer. This is because the sections are different
both in size and material, the plain channel is cold formed while the parallel flange
channel is hot formed, and they have different sectional properties.
In the section “Comparison between hot finished and cold formed hollow sections” we
have explained the differences between the two sections, and why cold formed
sections can not be used to substitute hot finished sections without rechecking the
capacity.
Section properties
The followings are taken from EN 10210-2 (1997), EN 10219-2 (1997) and BS5950 Volume 1 Design
Guide, 5th edition 1997
Corner radius ( r )
For hollow sections the corner radius are taken from EN 10210 and EN 10219, for hot
finished hollow sections and cold formed hollow sections respectively.
For hot finished square and rectangular hollow sections:
Nominal external corner radius for calculation is
ro=1.5T
Nominal internal corner radius for calculation is
ri=1.0T
For cold formed square and rectangular hollow sections:
Nominal external corner radius for calculation is
For thickness T ≤ 6mm:
ro=2.0T
For thickness 6mm < T ≤ 10mm:
ro=2.5T
For thickness T > 10mm:
ro=3.0T
Nominal internal corner radius for calculation is
For thickness T ≤ 6mm:
ri=1.0T
For thickness 6mm < T ≤ 10mm:
ri=1.5T
For thickness T > 10mm:
ri=2.0T
For other section types the manufacturers are using rules from various standard
specifications, which will take too much space to include in this handbook. Refer to the
respective country’s standards.
Second moment of area ( I )
The second moment of area of the section, often referred to as moment of inertia, has
been calculated based on first principal, by taking into account all tapers, radii and
fillets of the sections.

Radius of gyration ( r )
The radius of gyration is a parameter used in buckling calculation and is derived as
follows:
I
r=
A
1
2
where A is the cross-sectional area and I is the second moment of area.
For castellated sections, the radius of gyration given is calculated at the net section as
required in design to BS 5950: Part 1.
Elastic Modulus ( Z )
The elastic modulus is used to calculate the moment capacity based on the design
strength of the section or the stress at the extreme fibre of the section from a known
moment. It is derived as follows:
Z=
I
y
where y is the distance to the extreme fibre of the section from the elastic neutral axis
and I is the second moment of area.
For castellated sections the elastic modulus given are those at the net section.
For channels the modulus about the minor axis (y-y) is given at the toe of the section.
For angles the elastic modulus about both axes are given at the toes of the section.
Plastic Modulus ( S )
The plastic modulus is calculated based on the first principal, by taking moment about
the equal area axis. Only the full plastic modulus (S) is given in the tables. When a
member is subject to both axial load and bending, the plastic modulus must be
reduced to take account of the reduction in plastic moment of resistance. The details
for the reduction are given in BS 5950.
Buckling parameter ( u ) and torsional index ( x )
The buckling parameter and torsional index used in buckling calculations are derived
as follows:
For bi-symmetric flanged sections and flanged sections symmetrical about the minor
axis only:

elastic and plastic modulus) are given in centimetre (cm) units. Surface areas are in
square centimetres (cm2). Some of the sections have imperial sizes but the
dimensions and sectional properties for these sections are given in the metric system.
Mass and force units
The units for force, mass and acceleration are those of the Systeme International (SI).
They are the Newton (N), the kilogram (kg) and the metre per second per second
(m/s2) so that 1N=1kgx1m/s2. The acceleration due to gravity varies slightly from place
2
to place and for convenience a "standard" value of 9.80665 m/s has become
generally accepted in structural engineering. With this convention, the force exerted by
a mass of 1kg under the action of gravity is the "technical unit" of 9.80665N. In the
same way 9.80665 kilonewtons is the force exerted by a mass of 1 tonne (1000kg)
under gravity and 1kN the force from a mass of 0.102 tonne.

Comparison between hot finished and cold formed hollow sections
Introduction
The objectives of the comparison are to gain an understanding on the differences
between hot and cold formed sections, and subsequently, correct applications of the
sections.
Hot finished hollow sections have been successfully used in primary structures for
many years, but there is yet little experience with the use of cold formed sections. Cold
formed products differ from the hot finished in many respects. Therefore, their use in
primary structures must be approached with caution.
Thin walled cold formed open sections have been used in construction as secondary
members, such as purlins, for a long time. However, there is a growing trend of
manufacturing thicker walled cold formed hollow sections and the temptation to
introduce them into primary structures.
Cold formed hollow sections produced to EN 10219 are suitable for structural
use. However, they should not be used as a direct substitute for hot finished
hollow sections without reconsideration of the design capacity.
With the implementation of the European Standard for cold formed structural hollow
sections - EN 10219 - there exists a situation of identical grade designations for the
majority of the common strength grades used in both the hot finished (EN 10210) and
cold formed (EN 10219) standards. For instance, sections with yield strength of 275
N/mm2 and Charpy impact strength of 27 Joules at -20 degrees will have a grade
designation of S275J2H in both standards.
Common designation can lead to direct substitution and interchanging of the sections.
Since cold formed sections generally are weaker than hot finished sections it is
essential that products are specified accurately.
If a full designation of the steel is given to include both the standard number and the
grade/quality of the steel, substitution of cold for hot finished sections can be
prevented. For example, a hollow section of yield strength 275N/mm2 and a Charpy
impact strength of 27 Joules at -20 degrees should be designated as EN 10210
S275J2H for hot finished and EN 10219 S275J2H for cold formed sections.
The BS 5950 Part 1 (1997) are currently being amended, and with the increasing
tendency of using cold formed hollow sections in primary structures these sections will
probably be included in the new edition. The design rules are not very different from
those for hot finished sections, but there are some things a designer has to know and
take into consideration. For example, the corner radiuses, section properties, ductility,
corner cracking and welding. The differences between the two section types in
production, behaviour and design are investigated in this chapter.

Manufacture of hollow sections
Hot finished hollow sections
The manufacture of hot hollow sections involves a number of processes and cold
forming may be used initially. However, the hot finished product is characterised by the
final forming operation, which is always being carried out in the austenitic state (i.e.
above 920 degrees).
As a result, the forming operations do not affect the physical properties of the final
product, which are uniform around the complete periphery, including the seam weld in
continuously welded sections.
Cold formed hollow sections
The physical properties of the cold formed sections are significantly affected by the
method used in producing the strip, section forming processes and the final shape and
dimensions of the resulting section. The strip used for the cold formed sections may
be hot or cold rolled.
Plastic deformation and straining occur during the cold forming operations mentioned
below:
1) uncoiling of strips
2) strip flattening
3) forming into a round section
4) welding of round sections
5) circular sections formed into square or rectangle
6) straightening of the curved walls and corners formed
Note:
Square or rectangular hollow sections are not necessarily formed from round
sections, some manufacturers form the square or rectangle directly from strip.
Cold forming is known to increase the yield and tensile strength of the materials due to
cold working or strain hardening (see Figure 1). However, as the strength increases,
ductility decreases. And the process may result in a section in which the strength and
ductility vary considerably around the periphery. For example, a test specimen from
the flat face of the cold formed section will only indicate the conditions applying to that
face. There are also differences in the mechanical property transverse and
longitudinally on the section. Thus, cold formed sections must be used with
caution and proper design, especially in the use for primary structures.
There should be restrictions for the welding of cold formed sections. The corners of
these sections are subjected to high residual stress due to cold working. Welding
further induces the residual stress at the corners because of high local heating.
Corner cracking occurs when the yield stress of these cold formed sections is
exceeded by the residual stress built up at the corners.

Section properties
Cold formed rectangular and square hollow sections have rounder corners than the
hot finished sections. This is to avoid corner cracking from occurring during the
forming of cold formed sections, because of too sharp corner radius or too thick
sections.
However, the larger or rounder the corner radius, the smaller are the cross sectional
area, moment of inertia, section modulus and radius of gyration, etc. for a given size of
section compared with a similar hot finished section. Larger corner radii can make
fabrication difficult and require additional weld metal or profiling to produce the right fitup. This is a problem particularly when connecting one section to the face of another
section of similar size (see Figure 2), and can also add to fabrication costs.
The tight corner radii of hot finished
sections provide good preparation for
welding, especially where members of
the same width are to be welded
together.
The larger corner radii of cold formed sections
will require additional weld metal or additional
profiling to produce the required fit-up; both add
to fabrication costs, especially where members
of the same width are to be welded together.

Structural performance
For cold formed sections in tension, the variation of strength around the section could
lead to local over-stressing, which together with the reduced ductility in cold formed
sections could reduce the capability of the sections to redistribute loads.
As local stress redistribution often occurs even in elastic design, the maximum value of
yield/tensile strength ratio should not exceed 80%. This limitation is incorporated in
some standards (extract from “Hot formed RHS winning on points” from British Steel).
The ductility and Charpy impact toughness for sections to EN 10219 are equivalent to
hot finished hollow sections to EN 10210.
For the classification of cross sections the limiting width to thickness ratio will need
minor adjustments to take into account the residual stresses in the section due to cold
forming and the ductility of the material.
According to Europe Code 3 (ENV 1993-1-1:1992/A1:1994), welding of cold formed
sections should not be carried out in the cold deformed zones or within the adjacent
width of 5t each side, see Table 3, unless either:
-the cold-deformed zones are normalised after cold-forming but before welding;
-the thickness does not exceed the relevant value obtained from Table 3.

Table 3 – Conditions for welding cold-deformed zones and adjacent material
Due to stress relief effects, cold formed hollow sections are subject to greater
distortion than hot finished sections when subject to shot blasting, galvanising and
welding. This can cause local buckling, corner cracking and other deformations, and
will obviously have a large impact on the capacity when used as beams and columns.
Compression resistance
For compression members, the design strength should be based on the yield strength
of the cold finished section (as given in EN 10219) and not on that of the parent plate.

Because of the lower sectional properties and the residual stresses caused by the
manufacturing process, a lower column curve (curve C) is used for the cold formed
sections compared to curve A for the hot finished sections. This results in a larger
reduction of the compression strength. Figure 3 shows the column curves.

Web bearing and buckling
Formulae for buckling and bearing for hot finished hollow sections can be found in the
SCI Publication Design Guide to the BS 5950: Part 1; Volume 1 Section Properties
and member capacities and these may also be used for cold formed sections (extract
from New Steel Construction, August/September 1998).
Tension, shear and bending
Cold formed members in tension, shear, bending and lateral torsional buckling may be
treated in the same way as hot finished hollow sections (extract from New Steel
Construction, August/September 1998).
Summary
Light gauge open cold formed sections have been widely used for secondary
structures of steel-framed buildings, such as purlins. Concern is however on the use of
the cold formed hollow sections for primary structures. For a cold formed hollow
section of the same nominal size, thickness and grade as a hot finished hollow
section, the compression capacity dependent on the slenderness, can be 34% lower
than for the hot finished section.
The application of the current design rules on cold formed hollow sections might lead
to optimistic results, because the rounder corner radius for these sections can affect
the “web” buckling characteristics of the section.
Most design rules have restrictions on welding of cold formed sections due to the
residual stresses that occurs and to avoid corner cracking.

The advice is that there should not be direct substitution or interchanging of
sections without a capacity checking.
To avoid uncertified substitution the designers and quality surveyors have to know how
to visually differentiate cold formed and hot finished sections. A few things they should
know are:
• Because of the cold forming process the cold formed sections have a smoother,
sometimes oily surface, while the hot finished sections have a rougher surface.
If the sections are blasted or painted the corner radius and weld seam will indicate if
the beam/column is hot finished or cold formed.
• As mentioned earlier the corner radius of cold formed sections are rounder than the
corner radius of hot finished sections.
• The seam of welded cold formed sections are always on one of the flat sides, with a
distance from the corner, and on the same place for all members of the same
bundle, but for the hot finished sections the seam can be anywhere on the crosssection.
Fire resistance
There are several options to insure the fire resistance of steel structures. While hollow
sections can be protected on the inside, the outside or a combination of both, the
universal columns can only be protected on the outside.
Externally protected columns
For universal columns and unfilled structural hollow sections there are a number of
ways to protect the columns, including casing by plasterboards, cementitious sprays,
intumescent coatings or pre-formed casings, such as tube-in-tube systems. In all of
these cases the fire-protected structural hollow sections will have the minimum area
compared to all other similarly loaded columns in other materials.
Internally protected columns
Structural hollow sections have the advantage that fire protection material like water
or concrete, can be filled inside the columns. It is very simple to design a hollow
section with structural grade concrete filling. First, the column is checked for room
temperature loading, and then the fire resistance is checked, if required, an external
fire protection system is added. This method is very economic as it both minimises the
wall thickness of the hollow section, because of the concrete, and reduces the
thickness of the external protection system markedly below that of the unfilled section.
With use of concrete as internal protection of a structural hollow section, external
protection might not be necessary at all. The concrete filling will support the load
when the temperature has reached the point where the load bearing capacity of the
steel is under the actual forces imposed on the structure. The concrete core is
designed to carry the whole of the load at the fire limit-state. Plain concrete filling is
suitable for mainly axially loaded columns, while bar reinforced concrete is required for
columns with significant moments.
For externally protected columns the composite concrete filled, intumescent-coated
solution gives the smallest required columns. While for the internally protected
columns the bar reinforced concrete filled solution gives the smallest footprint.
Among all the four solutions the composite concrete filled, intumescent-coated column
gives the most economic solution.

Cost comparisons
British Steel in the United Kingdom has made a comparison between different types of
fire protection on hollow section columns and other steel sections. The study
compared options for a typical 7-storey internal column carrying a loading of 6kN/m2
on a grid layout of 7.2 metres by 6 metres. Where possible steel of design grade S355
was used, in general, this gives the most economical solution for structural steelwork.
In the case of internal protection, plain or bar reinforced concrete is assumed. In the
case of external protection, fire resistant boards were assumed for non-circular
columns, such as universal columns and rectangular/square hollow columns.
Three basic design options are possible for column design of structural hollow
sections, and British Steel looked at all 3 of them in this study.
Option 1: Columns are designed on a floor by floor basis or by grouping two or three
storeys together. The lightest steel section is selected for each column lift. This option
produces the minimum weight column with sizes reducing through the height of the
building.
Option 2: Columns are designed as in Option 1, but have constant external
dimensions throughout the height of the building. The column at the lowest level is
designed for the least weight solution and it is the external dimensions of this section
that are used for all other sections at higher levels. At the higher levels, the wall
thickness of the hollow sections is progressively reduced.
Option 3: Columns are designed as in Option 2, but the type of column selected is
optimised for all the columns over the height of the building rather than just the ground
floor, as in Option 2. Generally this means that the ground floor column is smaller and
thicker than that in Option 2, but the column serial size chosen allows the overall
weight of columns to be reduced.
Table 4 and Table 5 compares the costs of UC, CHS and RHS columns for various
methods of fire protection. Circled solutions are most economical.

Universal Beams and Columns
General
The section sizes of universal beams and columns are given in the tables on the
following pages. We have split up the sections in metric and imperial sizes because
the sections are rolled after different standard specifications.
The tables cover I-beams, IPE- beams, H-beams and HE-beams. The difference
between these beams is that the H/HE-beams have wider flange than the I/IPE-beams
and therefore look more like the letter H than the letter I, see Figure 4. In our
catalogue we put them all together to make it easier to make the ultimate choice.

Bearing Piles
General
The section sizes of bearing piles are given in the tables on the following pages.
Bearing piles are different from universal beams and columns because the flange and
the web thickness are approximately equal and the height and the width are almost the
same.
Figure 6 – Bearing Piles: Section shape
The standard specifications used for production of bearing piles in this region are
listed in this table.

HOT FINISHED ELLIPCON SECTIONS

Hot Finished Ellipcon Sections
General
Hot finished ellipcon sections are new and exciting section types. They come in two
shapes, one is an ellipse (ellipcon sections) and the other is half of an ellipse with one
flat side (semi ellipcon sections). Both shapes give the structures very outstanding
architectural looks, and the sections have many structural advantages.
The new elliptical sections are good alternatives to
traditional section types. They have all the properties
of the hot finished structural tubes, which are already
used in many construction works. In addition, the
architects are given full vent to expressing the
structure in creative and exciting architecture, and end
up with something both practical and aesthetic.
For structures with limited space these new sections
might provide smaller column footprints than other
design solutions, increasing the open floor area. Their
special shapes both serve the structural purpose and give continuity in the structure.
For non-symmetric load situations the sections might be more cost efficient than
circular or square hollow sections, because the designer can choose sections with
different stiffness about the two axis, x and y.
As for other hollow sections such as
square, rectangular and circular, the
ellipcon sections have constant external
dimension within the same serial size,
only the thickness is increasing. In other
words, the same column size can be
maintained throughout the full height of
the building, simplifying architectural
details and ensuring economy in
fabrication (See “Hot Finished Hollow
Sections”).
The tubes are produced according to EN 10210 Part 1 (1994): Technical delivery
requirements for Hot finished hollow sections, and Part 2 (1997): Tolerances,
dimensions and sectional properties. A few points are not included in EN 10210:
- The tolerance on the twist = 4mm +1mm/m length
- The tolerance on the straightness = 0.40% of total
length
- Section properties for the hot ellipcon sections are
not included in EN 10210.
The mechanical
properties of the hollow
sections, calculations of
torsional inertia
constants and torsional
modulus constants are
according to standards
ISO/DIS 657-XIV.

Super Hot Columns
General
In order to assure seismic safety in a steel structure, the seismic input energy has to
be absorbed. This can be done by utilising the deformation capacity in the plastic
range of the principal structural elements such as columns and beams. The important
property of super hot columns allows sufficient deformation capacity after a known
yielding and is used in these key structural elements.
In manufacturing the Super Hot Column, the steel is soaked and heated up to the
austenitic temperature range and hot finished into a square hollow section. This
results in homogenous properties around the whole cross section irrespective of its
position, both in flat plate portions and in corner portions. The material has the
following characteristics:
•
•
•
•
•
Uniform hardness, with no work hardening
Excellent elongation capacity, with a maximum yield ratio below 80%
High buckling strength, due to almost no residual stresses and no work
hardening
Excellent fracture toughness, due to no work hardening
Excellent weldability due to no work hardening and almost no residual stresses.
Product specifications
The super hot columns look like square hollow sections but are larger and have
slightly different material properties.
The material for Super Hot Column conforms to JIS G 3106 (1995) “Rolled steels for
welded structures” (SHC 520B and C) and JIS G 3136 (1994) “Rolled steel for building
structures” (SHC400B and C, SHC491B and C).

Hot Finished Hollow Sections
General
Structural hollow sections make beautiful, efficient structures with a nice continuity.
The hot finished hollow sections - square, rectangular and circular, have constant
external dimension within the same serial size, and only the thickness is increasing. In
other words, the same column size can be maintained throughout the full height of the
building, only changing the thickness, simplifying architectural details and ensuring
economy in fabrication.
When used in compression, as columns, hollow sections are more efficient than other
column types. The resulting reduction in structural weight can be as much as 1 storey
for every 9 storeys built.
Due to their high sectional properties hollow sections provide smaller column footprints
than other design solutions, with increased floor area.
Added together these qualities give an efficient and economic structure.
It has long been the opinion among structural people that for low-rise buildings only
concrete will be economical, but with multi-storey hollow sections steel structures can
compete with concrete. Steel might be more expensive per metric ton, but with the
fabrication and erection time, a lighter structure, labour cost, and easy maintenance
taken into account, a steel structure might give the most economic design.

Table 15 – Hot Finished Hollow Sections: Mechanical properties
Tensile test
The tensile strength, yield strength and elongation are determined from standard test
pieces, which may be the full section of the product or longitudinal or transverse strip
specimen. The location of strip test pieces should be away from the weld, for circular
hollow sections, and midway between corners on a side not affected by the weld, for
square and rectangular hollow sections.
The requirements of EN 10002-1: "Metallic materials - Tensile testing - Method of test
(at ambient temperature)", shall apply.
Charpy V-notch impact test
The test pieces for impact testing shall be taken longitudinally or transverse from the
test object. The location of strip test pieces should be away from the weld, for circular
hollow sections, and midway between corners on a side not affected by the weld, for
square and rectangular hollow sections.
Where thickness permits, standard specimens 10x10mm in cross-section are cut
longitudinally or transverse from the section and a 2mm deep V-notch accurately
machined into one face. The specimens, in accordance with EN 10045-1: "Metallic
CONTINENTAL STEEL PTE LTD

materials - Charpy impact test - Test method", are tested at the required temperature
according to grade.
If the nominal product thickness is not sufficient for the preparation of standard test
pieces (≤12mm), the test shall be carried out using test pieces of width less than
10mm, but not less than 5mm.
Manufacturing tolerances
Hot finished structural hollow sections are manufactured according to EN 10210: 1994,
Part 2, and the rolling tolerances are as shown in Table 16 below.

Notes:
1) The positive deviation is limited by the tolerance on mass.
2) For seamless sections the tolerance for the thickness is: thickness less than 10% but not less than
12,5% of the nominal thickness may occur in the smooth transition areas, but not over more than 22,5% of
the circumference.
3) Where the diameter to thickness ratio exceeds 100mm the tolerance on out-of-roundness shall be
agreed.
4) The tolerance on concavity and convexity are independent of the tolerance on the outside dimensions.
5) The sides need not be tangential to the corner arcs.
6) The positive tolerance on the mass of seamless hollow sections shall be 8%.
Table 16 – Hot Finished Hollow Sections: Manufacturing tolerances
All external dimensions, including out-of-roundness, shall be measured at a distance
from the end of the hollow section of not less than D for circular sections, B for square
sections and H for rectangular sections, with a minimum of 100mm.

COLD FORMED HOLLOW SECTIONS
91
Cold Formed Hollow Sections
General
Structural hollow sections make beautiful, efficient structures with a nice continuity.
The cold formed hollow sections, square, rectangular and circular, have constant
external dimension within the same serial size only the thickness is increasing. In other
words, the same column size can be maintained throughout the full height of the
building, only changing the thickness, simplifying architectural details and ensuring
economy in fabrication.
By using multi-storey columns the number of joints will be smaller and the number of
welds affecting the capacity of cold formed sections will therefore be reduced (see
“Comparison between hot finished and cold formed hollow sections”).
Due to their high sectional properties hollow sections provide smaller column footprints
than other design solutions, with increased floor area.
Added together these qualities give an efficient and economic structure.
It has long been the opinion amongst structural people that for low-rise buildings only
concrete will be economical, but with multi-storey hollow sections steel structures can
compete with concrete structures. Steel might be more expensive per metric ton, but
with the fabrication and erection time, a lighter structure, labour cost, and easy
maintenance taken into account, a steel structure might give the most economic
design.

General
Introduction
Light-gauge plain and lipped channels are cold roll-formed from hot-rolled steel
strips/coils of material according to JIS 3101 Grade SS400 (1995), or EN 10025
(1993). The sections are cold roll-formed according to JIS 3350 Grade SSC400
(1987), SPIM C100, SS104 (1996), or BS 5950 Part 7 (1992). The cold roll-forming of
channels produces sections with excellent mechanical properties and yet light in
weight. They are specially designed to ensure the ability to resist forces applied onto
them.
High-tensile galvanised C and Z purlins (sections) are cold roll-formed from high
tensile Zinc coated steel sheets according to ASTM A446 (replaced by ASTM A653
(1997) and A924 (1997). Due to the lightweight, the high strength of the steel and the
Zinc-coated surface, high-tensile galvanised C and Z purlins are versatile and
economic in use. They require minimal maintenance throughout the life span of the
buildings.
The light-gauge channels and high-tensile galvanised purlins are suitable for roofing
and wall cladding supports and for structural frames of buildings. Because of the
lightweight of the sections, no heavy equipment is needed to move them from one
place to another, or for the fabrication of the structure.

Storage and handling
C and Z Purlins should be kept dry during storage before use. They should be stacked
clear of the ground with timber sleepers and covered to prevent bundles from getting
wet. If bundles become wet during transportation or storage, the purlins must be
separated and wiped dry with clean cloth as soon as possible.
Care must be taken to prevent bundles or loose pieces from dropping to the ground or
banging against the building during loading and unloading, or when lifting onto the top
of the building.
Purlin selection tables for roofing application
A handy guide for selection of appropriate size for high-tensile galvanised purlins in
accordance with the bay width or column spacing of the building are given in Table 23
and Table 24. Note the given roof decking and be aware that these tables can only be
used for the specified loading. For other roof decking the designer has to calculate to
find the appropriate size.
The purlin selection tables are derived based on BS 5950 – Part 5 (1987): “Code of
practice for design of cold formed sections”.
The purlin selection tables are only applicable for a roof pitch less than or equal to
30° and for simply supported purlins with pinned joints over supports.
CONTINENTAL STEEL PTE LTD

Besides dead load arising from the roofs self weight, the purlins are designed based
on a live load of 0.25 kN/m2 (Malaysia Building Bylaw Clause 63) and uplifting wind
2
load of 0.50 kN/m .
i)
1.4 D.L. +1.6 L.L. (The most severe inward loading combination)
ii)
1.0 D.L. +1.4 L.L. (The most severe outward loading combination)
Under serviceability limit state the limiting deflection under total load is L/150
whereas under live load only is L/180 (where L is the purlin span).
The high-tensile galvanised purlins have yield strength of minimum 450 N/mm2.
All purlins shall have at least one bridging at mid span. For purlins in shaded areas
there should be two bridgings provided at lengths L/3 and 2L/3 between the supports.

Steel Sheet Piles to EN 10248 (1996)
General
The LX & Larssen (U-sections) profiles of steel sheet piling from British Steel are well
known to civil engineers throughout the world. Their usefulness and reliability in all
types of earth and water retaining structures have been proven on countless
occasions over many years. With the benefit of experience and research, the range
and efficiency of the sections has continually been improved.
A comprehensive range of section sizes is available, permitting the most economic
size to be made and a Frodingham straight web system is produced for construction of
cellular cofferdams.
The sheet piles can be used in river walls, ports and harbours, pumping stations,
bridge abutments, motorway widening retaining walls cut and cover tunnels,
underground car parks and for temporary works like supported excavations.
Pairing of the sections prior to delivery results in less handling and pitching operations
on site. LX & Larssen piles are normally supplied as singles, but can be supplied
interlocked in pairs if requested. If required, these sections can be supplied with the
interlocks welded together or crimped. The crimping process achieves a minimum of
80 kN per crimp and the pattern can be varied as required.
All piles are supplied with a 32 mm diameter slinging hole located 150mm from the top
end of the pile, unless otherwise agreed.

Recommended working stresses for steel sheet piling
Detailed below are the recommended working stresses for steel sheet piling (based on
current European practice and BS 8002:1994). The figures are for guidance only and
may be changed by the Client'
s engineer in line with national design codes. Stresses
in temporary conditions, which occur during construction, may be varied at the
discretion of the client'
s engineer.

Effective life
The effective life of unpainted or otherwise unprotected steel piling to EN 10027
grades S270GP and S355GP depend upon the combined effects of imposed stresses
and corrosion. Performance is clearly optimised with combinations of high stress and
low corrosion rate. Although other stress and corrosion combinations are less
favourable, good design can ensure acceptable lives. The use of grade S355GP steel
at grade S270GP stresses can also increase effective life. Copper-bearing steels are
marginally advantageous but only in atmospheric exposures.
Splices
Subject to recommendations on maximum lengths for driving, steel sheet piling is
generally available in lengths up to 30m. Where it is necessary to increase the pile
length during driving, splices can be used for which details are available on request.
Because of normal rolling tolerances there may be variations in the profile. Every effort
should be made to match pile ends before welding.

LX & Larssen Box Piles
Box piles, formed of two or more sheet pile sections welded together, can be
conveniently introduced into a line of sheet piling at any point where local heavy loads
are applied. They can be used to resist vertical and horizontal forces and are generally
positioned in the pile wall so that its appearance is unaffected.
Box piles can also be used as individual units as bearing piles for foundations and in
open jetty and dolphin construction where, due to their large radius of gyration, long
laterally supported lengths are practicable. The drawing under shows a LX & Larssen
Box Pile.

Frodingham Straight Web Sections
Dimensions and sectional properties
Straight web piling is used to construct cellular cofferdams, which are made up of a
series of interconnected cells. These structures are used when considerable depths of
water, or subsequently placed fill are to be retained, or when it is not possible to drive
far into the river bed, necessitating the need for a free standing gravity structure.
Typical uses are in dams to temporarily seal off dock entrances so that low level work
can be carried out in the dry, and in the construction of permanent walls for land
reclamation, quays, wharves and dolphins. The maximum length in which straight web
sections are supplied is usually 20m. Longer lengths can be supplied by prior
arrangement. Junction piles for the straight web sections are also available.

located in the centre of the pan at 200-250 mm from the end.
Piles can also be fastened together to form double piles by pressing or welding the
interlocks. Two to six pressing points per meter can be applied according to design
requirements. A minimum shear force of 80 kN per one crimping point is admitted.
