Manually Welded Heavy Duty Gratings are designed to meet the need for gratings 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 semi-trucks and trailers carrying maximum allowable highway loads, Heavy Duty gratings are manufactured in a wide variety of bar sizes and spacing.
BEARING BAR SELECTION: Once the bar spacing is selected, the bearing bar size must be specified based upon the anticipated load and the clear (unsupported) span to be served.
SERRATED SURFACE: Optional serrated bearing bars can be specified to enhance skid resistance. To maximize skid resistance, specify 100% Serrated grating. This Heavy Duty grating is manufactured with serrated bearing bars and serrated rectangular cross bars.
