Steel Grating

Steel grating can meet almost any load bearing or weight requirement and is the most durable grating for rugged applications. Bar grating is a top choice for strength, safety, and long-term cost.

Product Types & Features

Type “W” welded steel grating is manufactured by forge welding rectangular bearing bars and drawn cross bars. This welding process provides a positive, fused connection resulting in years of service under the most demanding conditions.

Type “SL” steel gratings are manufactured by inserting hollow tube cross bars into pre-punched holes in the bearing bars. The cross bars are then hydraulically compressed to form a positive mechanical connection. The cross bars are recessed below the top surface of the bearing bars providing a uniform and attractive architectural appearance.

Type “DT” steel gratings have deep rectangular cross bars and are manufactured by inserting pre-punched bearing bars and cross bars into an “egg-crate” configuration and deforming the cross bars under intense hydraulic pressure. The deep cross bars on type “DT” gratings make them popular for architectural applications such as sunshades and infill panels with the deeper cross bar serving as a distinct architectural accent.

Applications

Steel bar grating has a vast amount of uses that range from flooring and stairs to bridges and sewage drain covers. It is a smart choice for flooring and stairs in work areas where slipping and falling are a major concern, such as industrial plants, wastewater treatment facilities, or manufacturing operations. The open design makes bar grating the best option for areas that require the passage of light. It also works well for projects that require fast, easy fabrication and installation.

Flooring

Stairs, stair treads, and crossover platforms

Sewage drain covers, manhole covers, forklift traffic, and loading ramps

Racks and shelving
