Hot Dipped Galvanized Metal Grating Bar Safety Walkway Steel Grating
Steel Grating Introduction
steel grating is manufactured using an electro-forgewelding process that applies pressure and heat to fuse square, twisted cross bars into load-bearing bars of various thicknesses and depths.The result is a product of one-piece construction that complies with AS1657-2013.
The press welded galvanized steel grating/grille/grate is made of load flat steel bar and cross bar, placed horizontally and vertically, and at an equal pitch apart, by welding with 200-ton hydraulic resistance automatic welding equipment, then cutting,punching and banding ends.
