Welded Heavy Duty Gratings are designed to service applications subject to heavy rolling and static loads such as highways, plant floors, loading docks, inlet covers and airports. Since these conditions can range from light-duty forklifts to heavy-duty truck or aircraft traffic, heavy duty gratings are manufactured in a wide range of bar sizes and spacings. Steel Bar Grating with bearing bars thicker than 3/16" is considered to be "Heavy Duty" and carries the designation prefix "Type HD". 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.
Heavy-Duty Steel Gratings uses thicker <1/4"(6.3mm), 5/16"(8mm), 3/8"(10mm)> and deeper bearing bars. Heavy-Duty Welded Grating has the strength for heavy-duty load areas such as airfields, highways, industrial plants, truck and bus terminals, parking lots and railroad yards. Common uses are flooring, driveways, subway and tunnel ventilation grilles, curb inlet grates, ramps, docks, etc.
