Product Description

PLAIN

In its standard form, grating is supplied with plain load bearing barsand 6mm square twisted cross rods.

SERRATED

Serrated grating is available with most standard load bearing bars.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. When serrated grating is required it must be nominated. Use should be made of the serrated conversion factors when determining load bearing and spanning capacity
