PRODUCT FEATURES

Steel gratings consist of a series of bearing bars cross jointed by welding at various intervals with crossbars (twisted square bars, square bars, round bars, flat bars, etc.), to form a kind of steel products with square lattices among them. Their main applications are drain covers, steelwork platform panels, and steel stair treads.

Steel gates are generally made of carbon steel, and the surface is galvanized to prevent oxidation. It can also be made of stainless steel. Steel gates have the properties of ventilation, lighting, heat dissipation, non-slip, maintenance-free, etc.

* Application: Industrial platform flooring and walkway, traffic and steel structure, etc.

* Features: High strength, light structure; solid grid pressure welding structure makes it have a high load, light structure, easy to lift and other characteristics; beautiful appearance, durable
