ERW Steel Pipe Q235B

ERW welded steel pipe in Q235B for construction, scaffolding, fluid lines and mechanical tube.

Electric resistance welded pipe, made from Q235B

ERW pipe is the economical choice where seamless strength is not required: scaffolding, structural tubes, fencing, low-pressure fluid lines and mechanical applications. We supply Q235B ERW pipe from 1/2" to 16" in standard, round, square and rectangular sections.

ERW or seamless?

A practical rule: pressure and temperature-critical lines take seamless (A106), structural and low-pressure applications take ERW — at typically a third of the price. If your drawing is silent, tell us the medium and pressure and we will confirm which is appropriate, not just which is cheaper.

Surface and ends

Black, galvanized, or with primer; plain, threaded or grooved ends; scaffolding sizes with lock systems available.
