Nakoda Steel Industry is a manufacturer of Drawn Over Mandrel DOM Tubes Tubing, Our Manufacturing unit based in India, China, and Malaysia. Dom tubes manufacturing superior grade of steel like ASTM A513. DOM is a preferred choice for a wide range of mechanical tubing applications because it combines the advantages of closely controlled dimensions (OD/ID/Wall), superior concentricity, and a uniform wall thickness. In addition, DOM offers smooth OD and ID surfaces, high mechanical properties, and excellent machinability. DOM tubing is created from flat sheets of raw material, rolled on a weld mill to produce a mother hollow. A number of material options are available, including AISI class 1008, 1010, 1020, and 1026. The material is subjected to a normalizing heat treatment to produce a suitable tube for cold working. STOCKED SIZE RANGE: • 0.250” to 2.000” O.D. from 0.028” to 0.120” Wall Thickness We will Supply tubes from Malaysia, India & China.
