Rectangular shaped light-walled and heavy walled electric resistance welded (ERW) structural steel tubing, including ASTM A500-B Structural Tubing and ASTM A252 Piling Pipe. We source square and rectangular tubing from SeAHS Korean and Vietnamese production facilities, and from other unaffiliated Korean tubing companies. The uses for our structural products range from small and simple application (such as sign posts) to large and complex projects (such as columns for building and supports for factories).
