What does ERW mean on box section?

ERW stands for Electric Resistance Welded — the manufacturing process where a flat steel strip is formed into a tube and the seam is welded using electrical resistance. It is the standard process for structural hollow sections.

What sizes are available in 6m ERW box section?

Both square (SHS) and rectangular (RHS) profiles are available in 6m lengths. The range covers common fabrication sizes. Check the product page for the full list.

What is the difference between 6m and 7.5m box section?

6m is the standard stock length for ERW hollow sections and is easier to handle and transport. 7.5m gives longer unjointed runs but requires more space for delivery and storage.

Can ERW box section be used structurally?

Yes. ERW hollow sections are manufactured to BS EN 10219 and are used for structural frames, columns, beams and load-bearing fabrication across construction and engineering.

What finish is supplied?

6m ERW box section is supplied in raw mill finish — dark grey with light mill scale. It can be painted, powder coated, galvanised or used as-is for internal or temporary work.
