Welded Steel Bar Grating is the most popular of all grating platform types due to its strength, cost-efficient production and ease of installation.
Welded steel bar grating is resistance welded to create a rugged, one-piece constructed panel. The bearing bars are automatically resistance welded at the contact point with the cross bars and, under a combination of high heat and pressure, are fused together to form a permanent joint. The cross bars provide a high degree of rigidity, yet retain a smooth flat surface for free and easy walking.
Standard grating panels are 3 ft. wide x either 20 ft. or 24 ft. long. Panels are painted black; one end is untrimmed.
There are three kinds of welded steel bar gratings: plain style grating, serrated steel grating and I bar steel grating. They are widely used in steel structure platforms, stair treads, sidewalks, drainages and well covers etc. We are professional factory to design and manufacture standard steel grating and customize according to client's requirements.
