Serrated grating is available with most standard load bearing bars
(aluminium and steel only). The serrations are formed by placing a
series of notches along the upper edge of the load bar, thus enhancing
the non-slip characteristics of the grating.
* Use the serrated
conversion factors, shown on the Load Tables, to determine load
bearing and spanning capacity.
NB: Load bars: 20mm deep or 6mm thick, and stainless steel grating available in plain finish only (not serrated).
|
Webforge serrated grating is based on the Webforge serration profile, which complies to BS4592.
