steel grating  is a profile composed of orthogonal combinations of flat steel bars and fixed flat steel bars according to a certain distance. Flat steel is divided into general carbon steel and stainless steel according to different materials. Earlier, I-shaped flat steel was used. However, considering the processing cost and application function, it was gradually selected. The crossbars are divided into different shapes according to their shapes. They are mainly round steel, twisted square steel, and narrow flat steel. Twisted square steel is used more now. According to different processing methods, it can be divided into welding type and press-in type. The application of welding and press-in technology mainly depends on the application occasion. Now more is the choice of welding process. According to the different surface treatment processes, it can be divided into hot dip galvanized steel grating and stainless steel grating. Its application occasions include: petrochemical enterprises, waterworks, sewage treatment plants, port docks, municipal construction, food and drug processing enterprises, power plants and other enterprise units.
