A500 Carbon Steel Structural Tubing

ASTM A500 spec states that welded tubing shall be made from flat-rolled steel using electric-resistance welding. Longitudinal butt joints of welded tubing shall be welded across its thickness in such a manner as to assure the structural design strength of the tubing section. Welded structural steel tubing is typically furnished without the removal of inside flash.

ASTM A500 HSS are cold-formed, welded and seamless carbon steel structural elements in buildings, bridges and other load-bearing applications. Atlas manufactures squares, rectangles and rounds.
