Galvanized Welded Steel Mesh Grating Special Steel Grating for Floor Walkway
Galvanized Welded Steel Mesh Grating Special Steel Grating for Floor Walkway
Steel gratings consist of a series of bearing bars cross jointed by welding at various intervals with cross bars (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 bar grating is also known as steel grating. Steel grating is made up of parallel bars that are connected together with perpendicular bars. The bars are most commonly connected through machine pressure welding or manual welding, as the case may be. However, there are other ways of joining the bars together. Alternatives include riveting, close meshing (swaging), and press-locking. The most economical method of joining is determined by the materials used and the bars' thickness.
Steel bar grating is usually made out of carbon steel orstainless steel. It has a very high ratio of strength-to-weight and a lot of open space, making it a widely used option for industrial flooring. However, it is also used for things such as fire escapes, street drains, and bridges.
(1) Structure: Welding with flat steel and cross/round bars with certain distances.
(2) Features: High strength, light structure, high bearing.
(3) Surface: The hot dipped zinc coating gives the product excellent anti-corrosion.
