ALL Round Tubing is measured on the outside dimension and the wall thickness.DOM Round Steel Tube
is a welded mechanical round steel tube with the internal weld seam removed creating a smooth internal surface. DOM round steel tube has been drawn over a mandrel to produce a tube having more exact dimensional accuracy and tolerances, and a very smooth inside and outside finish. DOM round steel tube is ideal for more stressful applications requiring higher quality, increased mechanical properties, uniformity, strength, and soundness.
Welded Round Steel Tube
, also known as HREW, is a hot rolled electric welded round tube that is an very economical alternative to DOM Round Steel Tube. Welded Round Steel Tube is a structural grade tube that is suitable for a wide variety of applications where dimensional accuracy and precision tolerances is not a primary concern. The weld seam is present inside the tube.
Round Tubing is also made seamless in a cold or hot rolled finish.
