Heavy Duty Bar Grating - Industrial Bar Grating Suppliers

Our sturdy heavy-duty bar grating is resistance welded to ensure maximum strength, durability, and safety. We utilize 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 process creates a solid, permanent joint capable of withstanding 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?

Generally, you should opt for heavy-duty welded-steel bar grating in heavy-load areas, such as highways, parking lots, airfields, bus and trucking terminals, and industrial plants. It is the ideal choice for applications including driveways, heavy-vehicle tunnel ventilation grilles, loading docks, ramps, and other locations where vehicles frequently traverse grating. In these situations, loading the grating with bands is advisable to enhance its lateral strength. Additionally, grating with thicker serrations can provide extra traction for rolling loads.

Fabricated Heavy Duty Metal Grating

Heavy-duty metal grating from IKG® is designed for applications requiring maximum support of heavy or bulky loads, particularly in instances of vehicular traffic. It is available in two different cross bar configurations, which are hand-welded in place using conventional shielded gas methods.

Heavy-duty metal grating is tailored to accommodate heavy loads such as roads, highways, forklift traffic, industrial plants, and loading docks. This includes vehicular traffic up to H-20 loading capacity. Calculations for vehicular loading follow AASHTO Standard Specifications for Highway Bridges. Given the diverse applications, heavy-duty grating is manufactured in a wide range of bar sizes and spacings.

Other common applications include airfields, ramps, industrial flooring, driveways, highway bridge decking, concrete reinforcements, vault covers, trenches, offshore drilling rigs, and paper mills.

Industries such as transportation, construction, and petrochemical require specialized heavy-duty metal grating with a significantly higher safe live load. Our heavy-duty specialists frequently create bar grating to meet specific customization requirements. Contact us to learn more about our made-to-order special duty bar grating.
