heavy duty Serrated Welded Steel Bar Grating Step For walkway Application
Product descriptions
Heavy-duty steel grating can be made by welding and press-locked. It is higher and thicker than the ordinary steel grating. With the features of high strength, high bearing capacity and non-slip, heavy-duty steel grating is widely used as the floors, lanes and rack accessories in the highway, bridge, store shelves for large cargo, parking lot, industrial plant that often use forklift and the traffic junctions, roads or trails that large trucks often come and go.
