Galv welded grating floor, galvanized steel grid floor
Steel grating is welded by the world first-class equipment,which can arrange the bearing bar and cross bar
in longitude and latitude order to certain distance.cross bar is pressed into the bearing bar by high
tension resistance weldingring which is controlled by computer.so we can produce high quality gratings
withfirm welding,smooth surface and high strength.
