About A847|ASTM A847 covers cold-formed welded and seamless high-strength, low-alloy structural tubing with improved atmospheric corrosion resistance. This is weathering steel in tube form. Think Cor-Ten for HSS sections. Develops a protective patina like A588 plate. Used for exposed architectural tubing, bridge railings, and outdoor structures where unpainted weathering steel is desired. Compare to A500 (standard structural tubing, needs paint) and A588 (weathering steel plate).

About Round Tube|Hollow cylindrical stock for sleeves, bushings, spacers, and hydraulic cylinders. DOM (drawn over mandrel) tubing machines well and holds tight tolerances. Welded-seam structural tube is for cutting and welding, not precision work.
