Access flooring systems are raised floors that allow electrical and mechanical services to be installed beneath their surface. Access floor pedestals are vertical adjustable structures that support the panels that constitute the access floor above the substrate floor. Pedestals are fabricated steel items, zinc-plated and passivated. They are available in a range of dimensions, to allow different heights of the underfloor void and to accommodate different loadings on the installed access floor.
Isaac H. Grainger and Son offer four ranges of pedestals (H, M, E and X). All are produced in the same way using materials of identical composition but different dimensions (e.g. tube diameter, top and base plate thickness). All four pedestal ranges have been thoroughly tested in accordance with standard tests for access flooring such as T5, T8, T11, T15 and T16, coupled with a variety of panels.
This EPD applies to pedestals from Isaac H. Grainger and Sons most popular H range. H range pedestals meet the PSA MOB PF2 PS/SPU: March 1992 specification; the range includes 21 models to cater for different void heights. The sizes of the different models are shown in the EPD.
