Dom Tubes
DOM Tubes
Grace Steel Tubes is a manufacturer of Drawn Over Mandrel DOM Tubes Tubing, Our Manufacturing unit is based in India, China, and Malaysia. Dom tubes manufacturers superior grades 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 and rolled on a weld mill to produce a mother hollow. A number of material options are available, including AISI classes 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.
