Heavy duty steel grating handles heavier load than other 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.
Serrated surface (serrated bar), banded with the same size flat bar (end banding type), hot dip galvanized.
The minimum average hot dip galvanized coating required by standards AS1650, BS729 and ASTM A123 is 610gms/sq metre (the minimum average thickness of galvanized coating must be 87.14 μm).
Width: 600 mm / 900 mm / 1200mm
