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. Welded steel grating is cost-efficient production and easy to install. It is also resistance welded production for rugged and one-piece constructed structure, it can be fit various application.
