Technical Information

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.
