Heavy Duty Grating

Heavy duty Steel grating are economical, having excellent load characteristics and a slip-resistance surface. The Heavy Duty style handles a heavier load than other steel grating, adds angle noising, and provides additional support along the back edge of the tread to provide superior strength.

Floor grating - heavy duty ( see Fig. 1) specs as following:

The load bearing bars are produced from steel which conforms to the following equivalent standards: AS3679 Grade 250, BS4360 Grade 43A and ASTM A36 or equivalent.
