We produce welded steel pipe both on square pipes and rectangular hollow sections. The welded line can be controlled with our precision instrument in the fitting place. For rectangular steel pipe, the welded line will exist in small sides in order to stand heavy weight. Customers who request factories to produce rectangular steel pipes with welded line in small sides may have a project for steel doors or windows. Because the surface of big sides may be not even if it has weld line, that is not beautiful. Of course, there are no special requirements for round steel pipes weld line. Our professional degree can be illustrated by weld line control.
