With Frame Heavy Duty Steel Grating For Parking Lot Industrial Plant Highway Bridge Drain
Description:
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.
Standard heavy-duty bar grating is resistance-welded for durability, strength 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.
