DESCRIPTION The Steel Cementitious Air Tight System has been designed to minimise air leakage when the access floor is to be used as a plenum. The system achieves this by incorporating the use of a clip on air tight stringer that acts as a barrier in between the panels. |

Access Floor Panel
|
|
Type: SC Series - Steel Cementitious Size: The panels are 600mm x 600mm in size and are interchangeable with other panels. Also available are a series of load bearing finishing panels designed to minimise small off cuts experienced when cutting around columns, curved building designs and finishing off near perimeter walls. These finishing panels come in 600 x 800mm and 600 x 300mm sizes. Depth: 33mm Construction: The panel consist of a hardened steel top and bottom sheet plate with corrosion resistant protection, inside and out, encapsulating a structural cementitious core. Core: Cementitious Compound Tolerance: ±0.25mm and a flatness tolerance of ±0.5mm measured on a diagonal across the top of the panel Finish: ASP's standard powder coated finish. Connection: The panel is screw fixed to the pedestal head at all four corners

Panel Load Tolerances
AUSTRALIAN STANDARD (AS)
Safety Factor: Panels must provide a minimum safety factor of 3 times the concentrated load specified above in accordance with AS4154-1993.
CISCA STANDARD
Safety Factor: Panels must provide a minimum safety factor of 5 times the uniform load specified above in accordance with ICC-ES AC300.
PSA MOB STANDARD
Safety Factor: Panels must provide a minimum safety factor of 3 times the concentrated load specified above in accordance with PSA MOB PF2 1992.
Access Floor Pedestals
|
|
Size: 10,000mm² base plate
Locking: The pedestals will be provided with an adjusting and locking nut to maintain the assembly at a selected height, which requires a deliberate action to change the height setting, and which prevents vibration displacement.
Finish: ASP’s standard powder coated finish.
Connection: The panel is screw fixed to the pedestal head at all four corners
Finished Floor Height (FFH): The finished floor height of the access floor is measured from the sub-floor to the top surface of the installed access floor.
|
Access Floor Stringers
 |
Type: AT Stringer
Size: 600mm
Construction: The Air Tight Stringer shall consist of 0.8mm thick steel, with a 3mm sponge rubber finish to act as a barrier in between the panels.
Finish: Galvanized steel.
Connection: The AT Stringer clips into the AT cavity of the field pedestal to minimise the air leakage lost in between the panels.
