applications
Computer Rooms
Here are several reasons:
• Access floors distribute heavy weights equally
• Access floors manage the spaghetti of wires around
computer equipment and offer a safe environment
for personnel (no tripping)
• Access floors manage airflow to sensitive equipment
• Access floors provide grounding
• Access floors provide the needed flexibility for ever changing
hi-tech rooms
• Service outlets cut-in easy
Most computer centers have a surface covering known as High
Pressure Laminate(HPL). HPL has become the standard in
computer room design because of its ease of maintenance and
its unique ability to dissipate static electricity.
HPL is available in three different thicknesses: 1.4 mm, 1.6
mm, and 1.8 mm.
If you have heavy loads, you will want to definitely consider
an all steel floor that is filled with concrete. These floors
offer excellent rolling load protection as well as stationary
equipment protection.
Another consideration is the understructure. We have found
that with heavy loads, it is a much safer environment when
the grid is bolted. Bolting the stringers (cross-pieces) to the
pedestal (floor jacks) provides a rigid grid even when floor
tiles are removed.
5
General Office Environment
With the advent of mini-computers, terminals, and pc’s, the
landscape of the modern office changed. No longer can we
have one plug at our desk, we need a strip...make that two
strips. With a minimum requirement of a personal computer
at a desk, the wires in an office quickly became unmanageable
and uncontrollable. And not even entered into this equation is
the moving of employees throughout a building, their wires,
their phones, their fax, their ethernet wiring, or modem, etc.
It has different loading requirements, usually is not as high
as a computer room floor, and has contemporary carpet on it.
Usually these general office floors are lighter and less
expensive than mainframe type computer flooring. And if the
building can accommodate raised flooring during the design
and construction of the building, the owner of the building
receives savings in thousands throughout the life of the
building. Installing access flooring during renovations is quite
common, too.
If you are constructing a building, the way to guarantee the
future of your building is to install access flooring.
6
Equipment Rooms
Equipment Rooms are typically defined as areas that have
limited human access. Operators don’t sit in the room, the
equipment does. Usually equipment rooms have limited traffic
and the issue in these rooms is heavy loads, not rolling loads.
The weight of the equipment that will be placed on the floor
will determine the type of floor that is best suited for your
application. By selecting the Equipment Room category, the
Quick Selector Program will take into consideration average
loads for these areas.
7
Control Rooms
Access floors have become an industry standard in applications
for control room environments where the need to manage
wiring and static is critical. Raised floors offer the flexibility
in this environment to form the most efficient control rooms
to manage process control operations.
Here are several reasons to choose a raised floor in a
Control Room:
• Access floors distribute heavy weights of equipment equally
• Access floors manage the spaghetti of wires around control
equipment and offer a safe environment for personnel
(no tripping)
• Access floors manage airflow to sensitive equipment
• Access floors provide grounding
• Access floors provide the needed flexibility for ever changing control rooms processing equipment
• Access floors can be rotated, maximizing surface wear in
heavy caster wear areas, extending the life of the floor
• Service outlets cut-in easy.
Most control rooms have a surface covering known as High
Pressure Laminate (HPL). HPL has become the standard in
control room design because of its ease of maintenance and
its unique ability to dissipate static electricity.
One good factor about HPL is that it is resistant to many
chemicals that are found in industrial environments. Carpet
in working chemical plants is not recommended.
If this floor is located inside of a working plant, you will want
to definitely consider using a rigid grid bolted stringer (crosspieces) understructure system. Workers accessing under the
floor never seem to put the floor components back in properly
if the grid snaps (snap on stringers) in place. That is why it is
highly recommended to bolt the grid, to discourage workers
from disassembling the floor system.

Internet Service Provider
Internet Service Providers are growing at an unbelievable
rate! So are their terminal servers, their news servers, their
mail servers, their web servers, the servers they are colocating, the modem pools and the list of equipment goes on
and on and on.
What started for many in a back room has become the central
environment, immediately demanding cooling and wire
management.
Fortunately, most of them can install used raised flooring that
was previously installed in a mainframe computer room for
a fraction of the cost. It usually doesn’t have to be the finest
the quality unless they are making a showplace of the facility.
Any used or lightweight floor is perfect for an ISP application
of flooring.
9
Clean Rooms
Clean Rooms are environments that shall be totally clean.
No dust, no dirt, no particulates. The airflow is designed to
take microscopic particles down off the body, usually by a
grated access floor. These floors are all-aluminum and the
application is highly specialized. The floors are expensive
compared with mainframe type raised floors.
Clean rooms are typically found in hi-tech environments
such as biomedical, microelectronic, pharmaceutical and
laboratory facilities.
Here are some reasons why All Aluminum Access
Floors are used in Clean Rooms:
• They contain no ferrous materials to disrupt magnetic fields
• Air flow (Perforated) panels and grates provide optimum
laminar air flow
• They are available in a wide selection of conductive and
static-dissipative coverings or coatings to meet individual
requirements
• They offer excellent rolling load performance
• They are lightweight for ease of personnel handling
10
loads
Concentrated Load
Rolling Load
The maximum deflection and permanent set of an access floor
panel under load. When testing for a panel’s concentrated load,
a 25 x 25mm2 load is applied onto the surface of the panel at
its weakest point. The panel deflection and permanent set is
measured by recording the indentor movement.
The durability and/or deformation of an access floor system
when exposed to commercially anticipated caster traffic using
a specific load. Rolling loads are defined by the number of
passes, size and hardness of the wheel, and the combined
weight of the cart and its contents on each wheel.
In a typical office building scenario, concentrated loads are
typically imposed by stationary furniture and equipment with
legs.
These loads are typically imposed by equipment on wheels
across the access floor
Ultimate Load
Impact Load
The Maximum load applied onto the panel without failure.
When testing for a panel’s ultimate load, a concentrated
25 x 25mm2 load is applied onto the surface of the access
floor panel and this load is increased until the panel fails
structurally.
The effects and/or deformation of an access floor panel and
understructure, when subjected to heavy loads being dropped
onto the access floor system. This is to test the maximum
load that can be ?accidently? dropped onto the floor without
damage to the system.
This is sometimes expressed as a multiple of concentrated
load and referred to as a safety factor. A minimum safety
factor of two is recommended.
Uniform Load
Uniform load is static force equally applied over the entire
area of the panel and is typically imposed by stationary
furniture and equipment without legs. The uniform load rating
is specified in Newton?s per square metre.
Supporting Heavy Load
In situations where heavy loads need to be supported, it is
important that all information relating to that equipment
is considered before any decision is made, regarding
the suitability of a specific raised floor system. In some
circumstances, it will be sufficient to use a panel with a higher
load rating to accommodate for the extra load. However, there
are alternatives.
11
1.Additional pedestals can be introduced in high load or high activity areas, as illustrated below:
Axial Load
Is a vertical load applied to the centre of the pedestal due to
concentrated, rolling, uniform and other loads applied to the
surface of the access floor panel.
2. Spreader plates can also be used in order to distribute
the load evenly across a greater area. Spreader plates
are generally constructed using large sheets of 25mm thick
plywood.
Seismic Load
Overturning Movement
The understructure of the access floor system is the major
supporting element. As a result, careful attention needs to be
paid to the type of understructure you specify for your project.
Loads that are to be considered in Understructure
Support are:
Is a lateral load applied to the pedestal due to:
Rolling load traffic
Underfloor work due to cable installations
The pedestals ability to resist overturning movement is
determined by:
1- Its attachment method to the structural slab
2- Size and thickness of the base plate
3- Pedestal tube size
Is a combination of vertical and lateral movement, usually in
the form of earthquakes. When designing an access floor in
a location with high seismic activity, it is critical to have a
firm understanding of the seismic requirements of the access
floor and understructure from the onset, to avoid replanning
or reinstallation of an appropriate system to cater for those
needs.

Size:
600×600×35mm
Structure:
Steel raised floor is made out of good quality deep stretched
steel, which is punched, spot-welded and coated by epoxy
powder. It needs paraphrasing in order to clear the message
they are trying to convey
FEATURES:
• 60 perimeter welds compared to 40 in earlier design,
which greatly improves the panel edge loading capacity.
• The panel is put into a flatting press and checked for
flatness after welding.
Application:
Steel concrete composite in buildings, meeting rooms, and
similar facilities that requires dust proof and waterproof
floors.
Properties:
• There are 32 reverse structural embossments , one at the
intersection (center) of each structural cup which eliminates
the weak spots in the flat areas in the early design stages
and it also helps in the panel’s ultimate loading capacity.
• Panels come with 90 degree deep stretch steel beam
corners, filled with high strength cement. The load applied
on the panel will be transferred to the panel corners
before travelling through the pedestals to the sub-floor

Raised Access Flooring Most
Frequently Asked Questions
51
What is a raised access floor system?
A raised access floor comprises of load bearing floor panels
laid in a horizontal grid supported by adjustable vertical
pedestals to provide an under floor space for the housing and
distribution of services.
The floor panels are readily removable to allow quick access
to the under floor services.
What are the key components of a raised
access floor system?
The key components of a raised access flooring system can
be defined as follows:
Floor Panel
This is the horizontal load bearing component of a raised
floor. It is normally 600 x 600 mm (industry standard module
size) but can be 500 x 500 mm.
These floor panels will be supplied as either bare finished to
accept a carpet tile finish on site / marble tile finish or, with
a factory bonded finish such as: HPL, PVC or Vinyl.
Pedestal
This is the complete vertical, adjustable supporting structure
to the raised floor panels. The pedestals are normally bonded
to the sub floor using an epoxy resin based adhesive with
mechanical fixings also provided if required. The pedestal
assembly provides vertical adjustment of 30-40 mm to
allow the raised floor to be installed flat and level despite
undulations in the sub floor. The pedestal head provides panel
location and also when required a means of fixing the panel
to the pedestal head. .
Stringer
This is a horizontal component that connects pedestals
together. It connects to the pedestal head and is used to
provide additional lateral support at greater floor height and/
or increase the structural performance of the raised floor
system
52
Where is a raised access floor used?
Why use a raised access floor?
Raised access flooring is used today in a wide range of
situations where there is a significant level of building
services. Examples include:
Financial and Insurance offices
Government offices
General administration buildings
A raised access floor is used to provide a means of providing
a void below floor level which is capable of ensuring building
services are available at their required destination.
These services will typically include the following:
Electrical Power
Data
Telecom
Environmental Control/air Conditioning
Fire detection and Suppression
Security
Water and Drainage.
Where the use of computer/telecom
equipment is widspread?
Call Centers
Data Processing Centers
Telecom Switch Centers
Distribution Centers
Educational Facilities schools, universities, libraries,
research and development etc.
Retail Facilities
Industries requiring
Clean Room Facilities
such as for electronic and pharmaceutical.
The use of a raised access floor will allow quick and easy
access to these services for maintenance reasons. Also in
today›s modern office environment Churn is a major issue.
That is the number of times that the office layout has to be
modified to cater for changing requirements brought about by
new technology, new personnel or new tenants to a building.
53
What are the benefits of using a raised access
floor?
What are the alternatives to using a raised
access floor?
Raised access floors are used extensively to provide
the following benefits:
Quick and easy access to the ever increasing volume of power,
data and telecom services found within a modern building.
The alternatives are:
Suspended ceilings. High level trunking runs are above the
ceiling and services drop down at the required locations
through service poles. However any relocation, maintenance
etc is at high level thus causing major disruption to the office
area.
The underfloor void or cavity depth is often used as a large
duct for HVAC systems.
In speculative buildings premises need to be adaptable for the
needs of incoming occupiers.
Once occupied offices need to cater for office Churn and lend
themselves to new office organizations and layouts with the
redirection of services that implies.
Accessibility is a major consideration. People want easy
access to the services for maintenance, rerouting or upgrading
with as little disruption as possible to the work process.
Pre-cast trunking. This method was common in the 1970s.
Steel trunking is cast into the structural slab or topping
screed along pre-defined runs. No flexibility to cater for
future changes.
Skirting and Dado trunking. Steel or plastic trunking which
runs around the perimeters of individual rooms. Adequate for
small rooms but very limited for larger areas, also limited
cable capacity.
Furniture. Specialist furniture which encompasses in-built
service runs. Expensive and limited to vicinity of furniture
runs.
54
What types of raised access floor are
available?
There are two basic groups of raised access floor
system available each with their own advantages:
Gravity held or loose lay products. Here the floor panels rest
on the pedestal head. The panels are held in place by their
weight with lateral location providing engagement between
panel and pedestal head. These systems allow very quick and
easy access to the floor void and the panels can be readily
finished with factory bonded finishes.
Lock down or screw down products. In this case the floor panel
is screwed or locked directly to the pedestal head thereby
holding the panel in place and also providing lateral location.
This system provides a very solid and rock free floor with
quick and easy access to the floor void. However these systems
cannot accept factory bonded finishes.
What is the construction of a floor panel?
Steel/Cementitious panels
Here a structural steel shell comprising of a flat steel top and
a profiled steel base are welded together to form a hollow
shell. This shell is then filled with a foamed cement based
core to give a panel that gives good structural performance in
conjunction with excellent fire performance. In certain cases
the hollow unfilled steel shell will provide a floor panel that
gives suitable structural performance although its acoustic
performance is limited.
Calcium Sulphate Panels
Calcium sulphate panels are immensely strong and versatile.
They are ideal for raised floor areas requiring continuous
or hard finishes such as stone or large format porcelain.
This robust partial-access raised floor system makes it easy
to run services under the floor while its tongue and groove
design means that it is flat and smooth once installed. Calcium
sulphate panels are non-combustible with excellent structural
and physical properties. They exhibit a high standard of
acoustic and fire resistant properties.
Woodcore Panels
This panel construction comprises of a high density particle
board core that is encased by galvanized steel laminated
to the particle board by a structural polyurethane or epoxy
resin adhesive. This construction type is capable of providing
high strength and good fire and acoustic performance. By
varying the thickness of the steel sheet and the strength of
the chipboard core a wide range of structural performance
is available.
55
What are stringers and why use them?
Stringers are introduced for various reasons each with their
own specific design.
Bolt on Stringers
These are screwed into the pedestal head and are designed
as structural components and as such increase the structural
performance of the raised floor system. They will also provide
increased lateral stability.
Perimeter Stringers
These provide additional support to cut panels around the
perimeters if required by the project specification
What level of services is anticipated under
the raised access floor?
The anticipated use of the basic space in which the raised
access floor is to be used will determine the projected level
of power, data, telecom, HVAC and other services that will
be located under the raised access floor. This information can
then be used to determine the cavity depth required under the
raised floor and hence the finished floor height which will then
be used in specifying the raised access floor system.
56
What are the anticipated structural
requirements of the raised access flooring
in terms of static loads, rolling loads and
pedestrian traffic?
It is important at an early stage in the consideration of a
raised access floor that a detailed assessment is made of
the likely loadings that will be imposed on the floor surface.
These loadings need to be assessed in terms of:
Static Loads:
Uniformly distributed loads
Concentrated loads
Dynamic loads
Rolling loads
Vehicle configuration and weight
Pedestrian traffic:
Areas of high traffic need to be determined.
This information can then be used to determine the structural
requirements of the raised access floor.
Are there any standards governing the use
of raised access floors?
In August 2001 a European Standard was issued after
several years of consultation between all the European
manufacturers and was adopted as a British Standard in
November 2001, BS EN 12825 . The use of this standard is
increasing as it provides specifiers with increased flexibility.
This specification classifies raised flooring products by their
structural performance. Installation issues are clarified by the
Access Flooring Association Code of Practice.
Other standards regularly in use are:
CISCA The North American specification which often travels
with either the American client or American architects and
is regularly used internationally. This is an industry driven
specification and test method which is based upon individual
component testing.
57
What type of surface finishes are available?
The following range of floor finishes is available:
Bare finish
Here the floor panel will not be finished with a surface
covering. The surface of the panel will normally be the epoxy
powder coated steel top sheet. This bare finished raised floor
will normally be covered on site by the application of loose
lay carpet tiles.
Factory applied finishes:
The following finishes can be supplied factory bonded
to the appropriate floor panel:
Vinyl
Anti static vinyl
Static conductive vinyl
Linoleum
High pressure laminate
Rubber
Carpet
Wood in various forms
Marble
Stone, ceramic tiles.
Other finishes may be available after evaluation.
What range of finished floor heights (FFH) is
available?
Using standard pedestals finished floor heights from 75 mm
to 1200 mm are achievable. Bespoke solutions for lower and
higher options are available.
As a general rule above a finished floor height of 300 mm
stringers will be introduced to provide additional lateral
stability.
What is the exact definition of finished floor
height?
The finished floor height (FFH) is defined as “The nominal
vertical dimension from the specified sub floor level to the
specified finished floor level.
58
How is a raised access floor installed?
With regard to the physical installation of the raised access
floor within a basic space there are two main issues:
Finished floor height and level. Within a single floor area a
bench mark will be agreed between the floor installer and
the main contractor. This bench mark will be directly related
to the building bench mark. This will determine the height to
which the raised access floor will be installed. The raised floor
will be installed level to this BM by the use of rotating laser.
Set out of the raised access floor system. The set out of the
raised access floor is an important aspect in ensuring that the
raised floor operates satisfactorily throughout its anticipated
life span. Depending on the size and shape of specific floor
areas and size and location of any obstacles on the sub-floor
a range of solutions can be sought. Raised access flooring
panels are cut on site to fit at perimeter walls therefore a
best fit situation can be sought using the appropriate floor
panel module size. Ideally the setting out of the panels and
pedestals
can be coordinated by:
Working in line with other building modules to avoid
regular obstructions.
Working out from the centre of an area.
Working to column centers.
Cut panels should ideally be cut just under a full panel width
or a half panel width in order to minimize waste. Cut panels
of less than 150 mm width should be avoided in order to
maintain structural integrity. When it is not possible to avoid
small cut panels the following solutions are available:
In-board cutting, the principle of maximizing the size of a
cut panel by additionally cutting the last field panel adjacent
to the perimeter. On certain product ranges and structural
grades oversize panels are available as an alternative to the
above.
What are the site requirements?
The following site conditions are required for the installation
of a raised access floor:
Dry and watertight areas at a temperature above 40° and
a humidity below 75 % RH. This is required for both the
installation works and also for material storage.
Sub floor to be in the following condition:
Free from wet or dry contamination.
Able to accept epoxy resin pedestal adhesive and if required
mechanical fixings.
Any holes, joint lines etc in higher level sub floors should be
sealed in order to prevent floor sealer leaking through to the
level below.
59
The sub floor should be structurally strong enough to support
the raised access floor and the environment it supports.
The sub floor is required to be structurally strong enough to
allow the storage of raised floor materials prior to installation
The surface of the concrete sub floor should ideally be of a
medium tamp finish in order to give a reasonably flat surface
without inducing the formation of weak surface laitance.
A power float finish will normally give a excessively smooth
surface which will prevent the dust sealer and the epoxy
resin pedestal adhesive obtaining a good key and hence
good bond onto the floor surface. In order to achieve a good
bond onto a power float finish the subfloor will require to be
suitably prepared by mechanical means which will remove
weak surface laitance and provide a suitable surface for the
application of floor sealer and pedestal adhesive.
Will the raised access floor require to be
electrically earthed and how is this
achieved ?
In most cases due to steel used in its construction the raised
access floor will require to be earthed in line with local
conditions.
How to avoid problems associated with
raised access floors?
As the raised access floor performs a critical function within
the working office environment faults with the system can
cause problems from simple annoyance through to major
disruption. Many faults are rectifiable to a varying degree,
however it is essential to consider the following key factors to
prevent such occurrences.
Causes:
• Use of inappropriate products and/or solutions.
• Use of inappropriate class or grade of raised access floor.
• Poor quality products and/or installation.
• Raised access floor not lifted and replaced in accordance
with manufacturer›s instructions.
• Lack of appropriate maintenance.
Effects:
• Movement, rocking and squeaking of floor panels.
• Difficulty in removing and replacing panels.
• The floor may require modification in order to perform
satisfactorily.
• Areas of floor or the complete floor may require replacement.
• Possible floor collapse with likely damage and injury.
In order to avoid the problems outlined it is important that
the raised access floor be correctly specified at the outset.
This specification should include not only the product
requirements but also the installation requirements. Once
installed the raised floor must be maintained correctly in line
with the manufacturer›s instructions.
How should a raised access floor be used?
Raised access flooring panels should only be lifted using the
correct lifting device i.e. vacuum lifter or spiked carpet lifter.
Panels should be lifted vertically with no hinging movement.
Panels should be replaced in a vertical movement ensuring
that the panel is seated on the pedestals correctly. Only single
rows of panels should be lifted at any one time so as not to
leave pedestals independent of panels, as they are prone to
damage.
