Hollow sections





Ruukki has a comprehensive range in hollow sections extending to components and customer- specific grades. We produce longitudinally- welded hollow sections in the following dimensional ranges:

ShapeWall thicknessOuter dimensions

Round2- 12. 5 mm 26. 9 - 323. 9 mm

Square2- 12. 5 mm 25x25 - 300x300 mm

Rectangular2- 12. 5 mm 40x20 - 400x200 mm





Structural hollow sections - EN 10 219, available also as weather- resistant and hardenable grades. The simplistic form and excellent strength properties allow creating durable, light and cost- efficient structures.

Optim? hollow sections - High- strength sections have been developed for structures which require high strength and which are exposed to high stress conditions.

Raex? hollow sections - Wear- resistant sections.

Offshore hollow sections - Materials with excellent weldability, dimensional accuracy and properties in low temperatures and which comply with the requirements of e. g. NORSOK standard.

Combi tubes - For applications where weldability, formability and galvanising properties are more important than high strength.



We also support our customers with extensive processing and prefabrication services.
