Q235B Carbon Steel Welded Pipe – ERW Round Tube
ERW welded Q235B round pipe for structural, fencing, scaffolding and general conveyance applications.
Q235B carbon steel welded pipe is an electric-resistance-welded (ERW) round tube made from Q235B mild steel coil. It is the most cost-effective round pipe for structural and low-pressure conveyance applications.
Key Advantages
Cost Effective
Much cheaper than seamless pipe.
Wide Diameters
21.3 - 610 mm OD available.
Weldable
Easy field welding and threading.
Consistent
Straight, round and dimensionally stable.
