Hollow Section and Pipe Products

Hollow sections, black pipe, galvanised pipe and spiral pipe — a wide size range from structural work to water lines.

Hollow sections and pipes are produced by forming and welding steel strip. They are used in everything from structural work and plumbing to greenhouses and infrastructure; section, wall thickness and coating are chosen to suit the application.

Why we do not publish prices

Steel is priced daily. A figure we publish today would not be binding tomorrow, so we do not post prices anywhere on the site. Tell us the item, dimension and tonnage and we will share that day's price item by item, together with ex-stock delivery and warehouse withdrawal options.

Frequently Asked Questions

Questions About This Page

Which sections do hollow sections come in?

Square from 20×20 to 300×300 mm and rectangular from 20×40 to 400×200 mm. Wall thickness 1.00–12.00 mm, grades S235JR, S275JR and S355JR; standard EN 10219.

What lengths do the sections come in?

6,000 and 12,000 mm for hollow sections, and 6,000 mm as standard for galvanised hollow sections. If you need a different length, tell us and we will assess together how it can be solved.

What is the difference between black pipe and galvanised pipe?

Galvanised pipe is hot-dip zinc coated, black pipe is uncoated. Galvanised is preferred outdoors and on water and fire lines; black pipe in enclosed, dry structural work.

How thick is the zinc coating on galvanised pipe?

Hot-dip zinc coating of at least 55 µm. Diameter 1/2" – 6" (21.3–168.3 mm), wall thickness 2.00–5.00 mm and standard EN 10255.

Up to what diameter does spiral pipe go?

From 219 mm up to 2,020 mm. Wall thickness 4.00–16.00 mm, grades S235JR–S355JR and standards EN 10217-1 / API 5L; welded by submerged arc inside and out.

Which pipe is suitable for a large-diameter water line?

Spiral pipe. It is produced for large-diameter work such as transmission mains, drinking water conveyance and pile casing; at small diameters, black or galvanised pipe is the option.

Can the pipe ends be threaded?

Black pipe is available with plain or threaded ends. Threaded ends make installation easier in plumbing work; just state what you need when ordering.

Which should I choose for greenhouse and fencing work?

Galvanised hollow section. Because it stays outdoors, a coated section is needed; it is available in 20×20 to 100×100 mm sections, 1.00–3.00 mm wall thickness and Z100–Z275 coating.
