Type "W" Heavy Duty Steel Floor 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.
