What is Steel Grating?

It’s a grid like structure made of parallel steels bars that are joined at right angles by cross bars, creating a strong structure and adaptable platform. Steel grating is usually known for its high strength, lightweight design, load bearing ability and allows a good ventilation and light flow. It’s widely used in walkway platforms, stairs, drainage covers, fencing and safe flooring for factories.

Common Types of Steel Gratings

Welded Bar Grating

The most economical choice of steel grating product. This grating is manufactured by an electro-forgingprocess, welding rectangular bearing bars and cross rods. This welding method provides a positivefusion of cross rods and bearing bars. The most popular is the 19-4 spacing; with approximately 80%open area the 19-4 spacing allows for passage of dirt, snow, liquids, air and debris. Welded bargrating is also available in close mesh ADA conforming spacing for use in public areas. Differentbearing bar thickness can be specified, the most common 3/16" is stocked in multiple depths.1/8", 1/4" are stocked in limited quantities. Bearing bar thickness is offered from 1/8" to 1/2" toaccommodate any load rating requirements. Universally used in most general industrial plants as well ascommercial buildings; it has a wide range of uses such as walkways, platforms, safety barriers, ventilation grates.and drainage covers

Dove Tail Grating

This grating is a system of interlocking, perpendicular bars. It provides a smooth clean look ideal forarchitectural applications such as grilles, divers and screens. It is used in the same structuralapplications as its welded steel counterpart. It is offered in a range of spacing options from 7/16'to 1-3/16' Dove Tail grating is not recommended for rolling loads. Instead of welding the joints,tremendous hydraulic pressure is used to bond the two close-tolerance slotted bars together.Permanent locking is achieved by forcing the deep cross bar into the notched bearing bar.

Swaged Grating

Swaging is the least commonly used choice of connection for steel bar grating. This grating is similarin construction to our aluminum bar grating products. Rectangular bearing bars and tubular crossbars are joined together via the swaging process. This process keeps the material free from thewarping and weld flash inherent in the electro-forging process. This profile offers the sameflexibility as our other mechanically locked grating products as to multiple spacings (includingADA requirements), bar depths and finishes

Stainless Steel Grating

All forms of light duty and close mesh carbon steel grating are also available in stainless steel (both 304 &316). Stainless steel is great in corrosive environments and environments that need to keep clean such asfood and chemical plants. Welded stainless steel grating can experience discoloration during thewelding of the crossbars to the bearing bars. Passivation and bead-blasting are available to make thegrating stand out and appear new for years to come. This process also removes the discolorationcaused by welding. Swaged and dove tail options are popular for stainless steel as discolorationdoes not occur.
