Welded stainless steel tubes have rust resistance, excellent high temperature resistance,nice polishing surface etc.

Allin Metal Group Co.,Ltd manufactures and sells stainless steel tubes for construction and exterior applications,especially in automobile exhaust systems,decoration,tool etc.

It is produced by rolling strips of stainless steel into a tube and then welding along its full length. After welding, the weld seam, or bead, can be refined by cold rolling and forging methods. Welded tubing can even be drawn like seamless tubing to offer a better weld seam, and surface finish. Welded tubing can also be produced with thinner walls on larger diameter tubes, compared to seamless tubing. Because welded tubing requires less processing, it is typically quicker to produce as well as lower in cost than seamless tubing.
