Our factory produce ASTM A106, A36/A53 spiral welded black mild carbon square steel pipe. They are produced using mild carbon steel which excellent for construction and industrial purposes. Due to the spiral welding process that makes them even in all aspects and more rigid, they are normal option for heavy duty applications. These pipes are rust-resistant and can be customized in terms of size and thickness. They offer basic rust protection with a black finish.
