Steel Mechanical Tube
Steel Mechanical Tube is available in Welded Round (HREW) and Electric Resistance Welded (ERW) formats, offering a range of strength, dimensional accuracy, and cost-efficiency for demanding structural and mechanical applications. These tubes are commonly used in automotive frames, machinery, and industrial fabrications requiring strength and uniformity.
Steel Mechanical Tubing is a durable, high-performance material used across construction, manufacturing, and engineering industries. Its consistent wall thickness, strength, and machinability make it ideal for precision applications such as supports, frames, and rotating parts where reliability and versatility are key.

Steel Mechanical Tube, ERW and HREW Round Tubing, Structural and Precision Fabrication
Workability
Easy to weld, cut, form, and machine
Additional Notes
HREW is an economical alternative to DOM tubing when precision tolerances are not a primary concern.
ERW tubing is ideal for cold-formed welded and seamless structural tubing.
For higher strength, tighter tolerances, and more precise concentricity, consider DOM Round Steel Tube.
