As a supplier of steel tubing products, Harbor Steel stocks many sizes, shapes, and grades.

Cold Drawn Seamless Tube is normally drawn to o.d. and i.d. dimensions. Certain sizes must be drawn to o.d. and wall dimensions.

Hot Finished Seamless Tube is produced to o.d. and wall dimensions.

Welded D.O.M. Tube is an electric welded tube with all weld flash removed. Tested for weld soundness, drawn over a mandrel and retested. This product is superior in finish and wall uniformity to seamless tubing. Normally drawn to o.d. and i.d. dimensions.

Electric Welded Tube is produced to o.d. and wall dimensions. This is the least expensive mechanical tubing. It is produced from low carbon steel and possesses relatively good cold working characteristics.

Cold Drawn Butt Welded Tube is the least expensive drawn tube. It is produced from electric resistance welded hollows. Drawn to o.d. and i.d. dimensions. Not intended for pressure applications.

Pipe Size Round Structural Steel Tubing is produced by the electric resistance welded process. Uncoated. Not pressure tested. This product is less expensive than regular pipe and has higher mechanical properties and a better finish.
