hot dipped galvanized drainage grate trench cover plate metal walkway steel grating weight
Steel Grating /grate floor made by welding with flat steel and cross/round bars with certain distances. Our Steel Grating enjoy the feature of high strength, light structure, high bearing, convenience for loading and other properties. The hot dipped zinc coating gives the product excellent anti-corrosion.
Carbon Steel Bar Grating is an ideal option when your project requires a strong material that will not be exposed to an expressly corrosive environment. we suppliy both smooth and serrated bar grating. Bar gating is available in galvanized, painted black, plain steel, light duty, and heavy duty.
