Heavy Duty Welded Bar Grating Our sturdy heavy-duty bar grating is resistance welded to ensure maximum strength, durability and safety. We implement a specially developed automated electric/hydraulic welding technique that combines high pressure and high temperature to permanently fuse the bearing and cross bars together. This creates a solid, permanent joint that can withstand repeated heavy loads. We offer both heavy-duty carbon steel bar grating and stainless steel bar grating to meet our customers’ needs.
It is recommended that the grating be load banded when rolling wheel loads are used to provide added lateral strength.
- Standard widths: 2′, 3′, and 4′ in 20′ lengths.
- Standard bearing bars: 1/4″, 5/16″, and 3/8″ thick.
- Bars range from 1″ to 8″ deep

When Should You Choose Industrial 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 situations, as this will increase the grating’s lateral strength. Grating with thicker serrations can provide extra traction for rolling loads.
