Heavy duty load areas require a sturdier grating to ensure the safety of the load standing on, or traversing it, and to ensure that it maintains the same levelness over many years of use. It has wide applications: airfields, highways, industrial plants, truck and bus terminals, parking lots, railroad yards, etc. Some of the common uses are as flooring, driveways, subway and tunnel ventilation grilles, curb inlet grates, ramps, docks, etc. Whenever rolling wheel loads are to be used over the grating, we recommend that the grating be banded to add lateral strength. Anywhere that heavy duty grating is required, welded steel grating is your best choice.
Extra Heavy Duty Steel Grating Capability
Drexel Supply Co. has the capability of providing you with those really “big grates”. Our heavy duty fabrication department can fabricate grating far beyond the standard grating sizes.
Wide Range of Specifications
Standard heavy duty bar grating is resistance-welded for long life and safety using an automated electric/hydraulic welding process. High temperatures, combined with high pressure, fuse the bearing bars and cross bars together to form a permanent joint. Whatever your needs, you’ll find a grating to meet that requirement. Several choices of spacing are available, from a 1-3/16” or 1-3/8” close-mesh to a 1-7/8” or 2-3/8” open-mesh. All meshes come with your choice of either a 2” or 4” cross bar spacing.
Benefits of Heavy Duty Steel Grating
Strength is the greatest advantage of heavy duty steel bar grating. Its weight to load-carrying ratio is far greater than other flooring material, and offers many design possibilities. Properly designed and engineered, it’s capable of supporting the weight of a 747 airplane. Since cost-effective bar grating is available in variable widths, installation labor costs can be significantly reduced. Other cost-effective advantages are its maximized openness (80% open area) which allows for better drainage and inhibits the accumulation of dirt and other debris. We also offer serrations on bearing bars up to 3/8” thick, to provide additional traction for rolling loads.
