FOREWORD
0.1 This Indian Standard (Second Revision) was
adopted by the Bureau of Indian Standards on 22
July
1987, after the draft
finalized
by the
Structural
Sections
Sectional
Committee
had
been approved
by the Structural
and Metals
Division Council.
0.2 This standard
is one of a series of Indian
Standards
being
published
under
the Steel
Economy Programme.
This was first published in
1961 and revised in 1965.
In this
modifications
revision,
the
following
have been effected:
a) a series of zed sections
added,
major
with lips has been
b) box sections and the strength properties of
the various profiles have been deleted, and
c) the sectional properties have been expressed
to three significant
figures.
0.3 Cold formed light gauge steel sections are
produced from,steel strips or sheets generally not
thicker than 10 mm. For mass production,
they
are formed most economically
by cold-rolling,
while smaller quantities of special shapes are most
economically
produced on press brakes. The later
process with its versatility
of shape variation
makes this type of construction
as adoptable
to
special requirements
as reinforced concrete is in.
its field of use. Members are connected by spot,
fillet, plug or slot welds; by screws, bolts; cold
rivets or any other special device.
0.3.1 For the load carrying members like ‘Z’
sections, it is recommended
to manufacture
these
sections by cold roll forming process.
0.3.2 This type of construction
is appropriate
and economical
in one or more of the following
conditions:
a) Where moderate loads made the thicker hot
rolled shapes uneconomical
(for example,
joists, purlins, girts, roof trusses, complete
framing for one and two storeyed residential,
commercial
and industrial
structures,
and
stringer beams in conveyors);
b) Where
it is desired
{hat load carrying
members should also provide useful surface
(for example, floor panels and roof decks
mostly installed
without any shoring and
wall* panels); and
c) Where sub-assemblies
of such members may
be pre-fabricated
in the plant, reducing site
erection to a minimum of simple operations.
0.4 It is not intended
that the freedom
of
designers and/or manufacturers
should be limited
to the use of sections listed in this standard. The
flexibility
of the forming process and the great
variety of shapes which may be formed of sheet
and strip steel are such that substantial
economy
may often
be effected
in meeting
the end
requirements
by the use of special sections.
However, ‘the designer
is advised to seek the
advice of manufacturers
or fabricators
before
specifying special sections.
0.5 In the preparation
of this standard, assistance
has been drawn from BS 2994-1976 ‘Specification
for Cold Rolled Steel Sections’, issued by the
British Standards
Institution.
0.6 Illustrative
examples given in Appendix A of
IS : 81 l-1965 have been deleted. The designers are
advised to refer IS : SOI-1975* and SP 6(5)-19807
which
stipulate
the
design
criteria
and
commentary/
illustrative examples respectively on
the use of cold formed steel sections for structural
purposes.
0.7 For the purpose
of deciding
whether
a
particular
requirement
of this
standard
is
complied
with, the final value,
observed
or
calculated,
expressing
the result of a test or
analysis, shall be rounded off in accordance with
IS : 2-1960$. The number
of significant
places
retained in the rounded off value should be the
same as that of the specified
value in this
standard.

for cold formed light gauge

general applications,
having minimum
thickness
of 1.25 mm.
5.1 Sheet
and strip used for making the coldformed sections shall conform
to a grade not
lower than St 34-1079 of 1S : 1079-i973*.
51.1 Sheet and strip conforming
to IS : 51319867 (other than Grade ‘0’) may also be used
for sections where load bearing is not a design

false ceiling, sections for
frames of doors and windows.
