UNITILE’S LOW FLANGE PANEL

LIMITATIONS OF THE

CONVENTIONAL STEEL CEMENTITIOUS PANEL

Current design of raised access floor system with bolted stringers in existence for the last 15 to 20 years.

Very minor improvisations made in the design & engineering of the product, for better technical performance & benefits during time of installation.

Unitile has successfully done value engineering & re-designing of the conventional access floor system.

The new system designed by Unitile addresses all the common customer complaints associated with conventional access floor systems.

Unitile’s Low Flange Panel design and re-engineered understructure system enhances the technical performance of the system while ensuring ease of installation at site.

Flange Width:

12.50 mm

Flange Width:

8.00 mm

Conventional Flange PanelOLD Low Flange PanelNEW

Drawbacks of a higher flange width Cantilever Panel are:

• The unsupported cantilever edges of the panel are vulnerable to damage due to site accidents during installation and frequent handling of the panel to handle underfloor services.

• Higher flange cantilever panels are often exposed to more risks of damage at site.

Advantages of a low flange width Cantilever Panel are:

• 36% decrease in cantilever edge.• Reduced and low cantilever edges of the panel provides

higher strength to the unsupported edge thus leading to reduced risks of damage due to accidents and frequent access of the panel at site.

• A low flange width panel of the same grade will perform better on all technical parameters as compared to a standard flange panel of the same grade.

*Numbers are a close representation of worldwide panel manufacturers.

36%Decrease in Cantilever

Edge

The narrow beam limits the overall stability ofthe system, often leading to common customer

complaints such as instability and rocking ofthe panels.

Beam Width:

16.50 mm

Beam Width:

19.50 mm

A wider beam width increases the overallstability of the system and enhances its

technical performance.



Foot Print Area resting on the

Pedestal Head:427.88 sq. mm

Foot Print Area resting on the

Pedestal Head:730.35 sq. mm

71%Increase in Foot Print

Area

Lower foot print area leads to instability and rocking of panel incase of overlapping or play

in the system.

Increased footprint area leads to better stability of the system and also eliminates overlapping

and rocking of the panels to a large extent.



Cantilever unsupported edge of steel flange at the

corner:30.10 mm

Reduced Cantilever of the

steel flange at the corner:

19.60 mm

Higher radius (30 mm) leads to increased cantilever of the unsupported flanges at the diagonal corner of the panel.

Lower radius (15 mm) decreases the cantilever of theunsupported flanges at the diagonal corner of the panel.



The draw backs of the above visible gaps between the panel& stringer:

• Floating Panels: The panels are floating with gaps all around the perimeters.

• Misalignment problems: Misalignment issues hampers the floor leveling at site

• Overlapping panels: Overlapping of panels hampers the floor leveling at site and leads to uneven floors.

• Edge Beading Damage: Overlapping of panels leads to the abuse of the edge beading and the possibility of permanent detachment from the panel perimeters.

GAP between the Panel and Stringer

The advantages of no visible gaps between the panel & stringer:

• Tightly fitted Panels: The panels are snug fit to the under structure grid system.

• No Misalignment: Early warning to installer to take corrective action fast since the system perfectly fitted at right angle and panels do not fit in case of misaligned grid.

• No Overlapping of Panels: The system design prevents the lateral movement of the panels, hence the chances of panels overlapping are almost negligible.

NO GAP between the Panel and Stringer


Due to the unstability of the system, squareness of grid is not 100% and hence panels do not fit in

full alignment with the understructure system during and post installation access.

Improves load carrying capacity as the stringers are box type instead of open “C” type stringer

previously used.

PVC EDGE BEEDING INTEGRAL TRIMv/s

Edges slightly unstable dueto lack of support

Edges more stable.

STABILITY

PVC edges tend to peel offwhen frequently accessed.

Edges are an integral part of laminate and hence eliminates the risk of peeling.

PANEL EDGE

PVC beeding tends to rub against the adjacent panel and generates a

creaking sound.

As there is no PVC, there is no friction generated leading to a noise neutral floor.

SOUND

Panel joint is 10 mm wide. Sleeker joint width of 6 mm

AESTHETICS

RAISED ACCESSFLOOR SYSTEMS

Nex - Gen

COMMON CHALLENGES FACED IN DATA CENTERS & CONTROL ROOMS

The 600mm center-to- center distance in

a conventional Raised Access floor system causes the

followingchallenges:

Reduced plenum space

below the floor.

Obstruction of larger services

running beneath the

floor.Fouling of the

cable tray systems with the

pedestals.

Limited space available for work during maintenance of the facility.

Heavy density of cables in data centers makes cable management challenging

NEX-GEN RAISED ACCESS FLOOR SYSTEM

Unitile has reengineered the conventional

raised floor system design to overcome the

challenges faced in the Data Centers and

Control Room environments.

Our all new Nex-Gen access floor system

has been designed to provide a wider

span for cable management during the

construction and ease of maintenance

post-handover of your facility!

NEX-GEN SYSTEM DESIGN FEATURES:

Center to center distance of 1200mm

Surface Area: 2400 SQ. MM.

Unitile Nex-Gen Access floor system having a center to center distance of 1200mm and with a surface area of 2400 sq.mm provides the following advantages:

A 1200 mm wide plenum space below

the floor enables

convenience of cable routing.

Lesser obstruction to larger services running below

the floor (above 500 mm).

The wider span prevents fouling

of cable tray systems with the pedestals.

Ease of maintenance

during construction

program.

Ease of maintenance

post-handover for the life

cycle of your facility.

Lesser number of pedestals required.

Faster installations at

site due to lesser

pedestal.

Can integrate with Unitile –

Multilayer underfloor grid

system to provide the

benefit of elevated cable

tray:-

Elevated cable tray prevents

the contact of the cables and

trays with floor water /

dampness.

The unique feature prevents

fouling of cable tray with

pedestal.

Path for cable trays are

predefined and hence

supports the contractor for

doing a neat and clean

installation.

Lesser number of

pedestals required due

to center to center

distance of 1200mm as

compared to center to

center distance of

600mm built in a

conventional raised floor

system

Lesser number of pedestals required

Advantages due to lesser

number of pedestals

required :–

Lesser holes drilled in the slab

hence maintaining the structural

integrity of the slab.

Lesser drilled holes also leads to

lesser generation of dust on the

floor (3.30 pedestal x 4 holes per

pedestals x area in sq.mt is the no

of holes that have to be drilled in

the mother slab to get correct

anchorage of the pedestal to the

slab for stability of the system).

Faster installation compared to

conventional raised floor system.

Major challenges offield-cut panels of width200mm & below

Rocking of the panels

Unstable system

Panels not fitting properly

Poor structural performance

Cement and dust generationon loading

</=200 mm

ALL-NEW SOLUTIONFOR DATA CENTERS

With usage of 600 x 800 mmpanels, the under floor space canbe used to accommodate wider services (restricted load carrying capacity upto USF 1250 only).

With the earlier panel size of 600 x600 mm, the additional 200 mm small cut panels would have to be cut and used along the periphery or near racks for data centers, now with the availability of 600 x 800 mm panel, need for smaller size cut panels is eliminated.

600mm x 800mm panels

600MM X 800MMPANEL FOR PERIMETER

Modular and flexible solution to brace the raised floor pedestal which can house the cable trays and power sockets directly fitted on it.

Since the system is adequately braced in all direction, it eliminates the anchoring (drilling the floor slab) of the pedestals and reduces dust generation within the facility. However, these pedestals are secured with the glue to the subfloor.

Multiple layers can be accommodated to suit the requirement at sites wherever necessary.

Improves the dynamic stability of the system.

By virtue of anchoring all the understructure grid with cable management system, the system is also seismic compliant to Zone 4 (highest in its class).
