Manufacturing Technique
Cutting large steel plates as your requirements to make the surface of the plate bright by miling and grinding, also can make holes and make angle degrees,and can weld by your drawing.
For the thickness under 30mm, cutting by laser; For thickness over 30mm, mainly OXY-cut, flame cutting.
For the thickness 200mm steel plate, because during the flame cutting, the temperature is very high, so the cutting parts steel plate might be broken at the angle part, then our workers will repair the angles to be good condition.
