Why is DOM tubing better than HREW tubing?
DOM (Drawn Over Mandrel) tubing is better because it is one solid piece, there are no seams or weak points in the tubing itself. HREW (Hot Rolled Electric Welded) is a flat piece of steel that is rolled and then welded to make a tube. DOM construction normally provides a 30-40% strength increase as a structure. DOM tubing also offers precise and consistent inner and outer diameters. All fabrication and parts construction at ORS is performed with DOM tubing.
