Rigid Pressure Locked Steel Grating , Bearing Bar Metal Grates For Decks
Heavy Duty Steel Grating For Highways Plant Floors Loading Docks and Airports
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.
Press-locked grating also can be called pressure locked grating. It is a kind of steel grating with high strength, we can add more serrations on the surface to provide addition security. Press-locked steel grating is mainly used in the civil and commercial construction, theater, subway, suburban railway, municipal works.

Type "W" Welded Steel Grating
Our most economical steel grating products, type "W" welded steel gratings are manufactured by forge welding rectangular bearing bars and drawn cross bars. This welding process provides a positive fused connection providing years of service under the most demanding conditions. Type 19-W-4 steel grating is our most popular product and is recommended for nearly all industrial flooring applications.
With nearly 80% open area, 19-W-4 allows for the easy passage of dirt, debris, snow, and liquids and is essentially self-cleaning. Type "W" gratings are available in close mesh, ADA conforming spacings 11-W-4 and 7-W-4 which are commonly used in public areas. When specifying type 11-W-4 for ADA applications, 3/16" thick bearing bars must be specified.
