Serrated Surface Welded Steel Grating
Welded steel grating is the most popular type among all types of steel grating, also called metal open bar grating. It is also the most widely used type.
Welded steel grating is produced through automatically resistance welded. The bearing bars and cross bars are resistance welded under high heat and pressure to form a permanent joint. This technology can not only ensure the rugged structure of welded steel grating, but also can retain a smooth and flat surface, which is easy and free to walk.
