    Round Tube Defined

    DOM vs HREW

    We offer DOM (drawn over mandrel) and HREW (hot rolled electric-welded) tubes. The main difference between the two is their strength.

    Drawn Over Mandrel (DOM)

    DOM tubing starts with a welded tube which is then forced through a die to bring it down to its desired shape. The process results in a tube that is seamless inside and out, and a yield strength of up to 70 ksi (kilograms per square inch).

    Hot Rolled Electric-Welded (HREW)

    Conversely, HREW tubing has a visible seam on the inside and outside of the tube, and a yield strength of 40 ksi.

    Round Tube Metal Types

    Hot Rolled


    There are many differences between hot rolled and cold-finished steel. The first is the process. Hot rolled steel goes through one high heat treatment process, while cold-finished steel requires further processing. After cooling to room temperature, cold-finished steel is then rolled again. This additional treatment process results in a stronger metal that can be used for more precise applications or projects that require a smoother aesthetic appearance. Compared to cold-finished steel, hot rolled steel surfaces are rougher. Hot rolled steel is typically used in applications where precise shapes and tolerances are not critical.
