Round Tube - HREW/CREW

Steel Round Tube is the most economical of the round tubes. It can be HREW (Hot Rolled Electric Welded) or CREW (Cold Rolled Electric Welded). Each of them are produced using Hot Rolled steel strip or Cold Rolled steel strip passed through a series of rollers and electric resistant welded to produce a round tube. The weld seam on the outside is removed but the inside weld seam remains.
