Steel gratings are usually painted steel grating, stainless steel gratings and hot-dip galvanized steel grating. The hot-dip galvanized steel grating is the most widely used. Hot-dip galvanized steel grating is made of load flat steel and cross bar arranged at a certain distance and longitude and latitude. It is welded on the high-voltage resistance welding machine to form the original plate. The finished products are processed by cutting, cutting, opening and wrapping processes, and then processed by hot galvanizing.
Hot DIP galvanized steel grating has three kinds of steel gratings, they are Plain Style Steel Grating, Serrated Style Steel Grating and I Bar Type Steel Grating. They are widely used in steel structure platforms, stair treads, sidewalks, drainages and well covers etc. We can design and manufacture standard steel grating and in customized shapes per client's requirements.
