Steel Bar Grating with bearing bars thicker than 3/16" is considered to be "Heavy Duty" . Available bar thicknesses are 1/4" (6.4mm) , 5/16" (7.9mm) and 3/8" (9.5mm) in either plain or serrated surface. Standard depths range from 1" (25mm) up to 4" (102mm), although larger sizes are available upon request.
Weld Heavy Duty Steel Bar Grating is commonly used for floor trenches and sump covers exposed to heavy equipment traffic. It is used extensively through out mining, power generation, highways, airfields, and on truck terminal loading docks and ramps. It is suitable for large single span conditions or where grating must be support extreme loads.

When Should You Choose Heavy-Duty Welded Bar Grating?
In general, you should choose heavy-duty welded-steel bar grating for use in heavy-load areas such as highways, parking lots, airfields, bus and trucking terminals and industrial plants. It’s the ideal choice for products such as driveways, heavy-vehicle tunnel ventilation grilles, loading docks, ramps and any other places where vehicles roll over grating on a repeated basis. It is also a smart idea to load-band the grating in these situation, as this will increase the grating’s lateral strength. Grating with thicker serrations can provide extra traction for rolling loads.
