The gutter cover is designed and manufactured by pressure welded steel grating, which has long been widely used in Europe, America, Japan, Australia and other countries. In China, gutter covers have been widely used in municipal, garden, parking lots, factories, highways, docks and airports.
Steel grating is made of the world's most advanced, PLC-controlled high-voltage pressure resistance welding machine, the manipulator automatically puts the crossbar (twisted square steel or round rod, the same below) horizontally on the evenly arranged flat steel, through the strong 1600KVA electric welding power and 1000KN hydraulic pressure to weld the crossbar pressure into the flat steel, so as to obtain the steel grating with strong solder joints, stability and strength.
Stainless steel grating&Composite steel grating
Various specifications of stainless steel grilles can be made according to customer needs. Compared with carbon steel grating, stainless steel grille is not only more beautiful, but also has the function of corrosion resistance and rust prevention, which is widely used in food processing and automobile industries.
Press-lock steel grating is the use of large-tonnage hydraulic machine, the use of press-in process production, it will be processed by machine tool blanking, with special notches of load flat steel with pre-cut insert flat steel pressed together, vertically arranged load flat steel and insert flat steel form a very unified network structure.
