Higher security and firmness 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. |
The galvanized surface of the product is smooth and beautiful. | Our galvanized zinc coating thickness exceeds the peer standard. |
