Q235B碳钢焊管 – ERW 圆管
ERW welded Q235B round pipe for structural, 击剑, 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.
主要优势
成本效益
Much cheaper than seamless pipe.
Wide Diameters
21.3 – 610 mm OD available.
