Anti-skid steel grid plateis available with most standard load bear- ing bars. The serrations are formed by placing a series of notches along the upper edge of the load bar, thus enhanc- ing the non-slip characteristics of the grating. When serrated grating is required it must be nominated (eg. SA325 Series 1 serrated). Use should be made of the serrated conversion factors, shown below the Load Tables, when determining load bearing and spanning capacity.
