According to the shape of the surface,they can be divided into tooth-shaped steel grating, pressure welded steel grating, I-type steel grating and composite steel grating.
 According to the surface treatment,they can be divided into hot-dip galvanized steel grating, spray paint steel grating, stainless steel grating and original steel grating.

We use machine pressure welding and high-voltage resistance pressure welding machine. The manipulator automatically places the crossbar on the flat steel which is arranged evenly. Through strong electric welding power and hydraulic pressure, we can press the crossbar into the flat steel, so that we can get the high-quality steel grading with strong welding point, stability and high strength.
