Steel Tubing Products

Carbon steel tubing is widely used for its strength, durability, and cost effectiveness. Most steel tubing is produced by folding flat steel stock and welding one seam to create the tube, or feeding seamless piping through a die that squeezes the cylindrical pipe into a square or rectangular section tube. Various grades of steel are available for industry-specific applications. 

A500 TUBING: Made from flat-rolled steel, ASTM A500 structural tubing is welded with an advanced ERW welding system to ensure a reliable seam. Welded steel tubes are produced via an ERW welding process where a continuous weld seam joins the edges of the folded plate.

ASTM A847 TUBING is typically left unpainted. Over time, the surface develops a protective layer of rust that inhibits further corrosion. The added structural efficiency of A847 Steel allows for a lighter wall thickness than what would be needed for carbon steel tubing.

Carbon steel tubing is widely used for its strength, durability, and cost effectiveness.
