From design to finished part
Steel lets you build big. From a single bent beam to a complete curved construction, we bend with roll, mandrel and induction bending, cut with 3D robots and weld the parts together. One partner for the whole route.
Co-engineering from the first design
Involve us while the design is still open. We advise on profile, radius and steel grade, so the construction is buildable, efficient and true to your design.
Steel bending in 2D and 3D
Roll bending for large radii, mandrel bending for tubes and pipes, induction bending for heavy sections with tight radii. Each technique matched to your profile.
3D robot cutting and welding
Our 3D cutting robots give bent profiles precise cuts and bevels, so every connection fits. We then weld them into larger sections, built to the required standard.
Steel fabrication and assembly
We assemble the parts into a complete construction that arrives on site ready to install.
When customers come to us
“We need curved steel beams for a roof that match the architect’s design exactly.”
We bend beams to the exact radius and advise early on profile and grade.
“Our design has a heavy steel section with a radius that seems too tight to bend.”
Induction bending makes tight radii possible in heavy sections.
“We need a complete curved steel structure, welded to EN 1090.”
We bend, cut, weld and assemble, so it arrives ready to install.

Frequently asked questions
It depends on the profile, its size, the steel grade and the technique. Roll bending suits larger radii, while induction bending reaches much tighter radii in heavy sections. The capacity sheet shows our standard limits per profile. Close to the edge? Send us your drawing: often more is possible.
Roll bending shapes a profile gradually between rolls, cold, and suits large radii and long lengths. Induction bending heats a narrow zone of the profile and bends it step by step, which allows tight radii in heavy sections with little deformation. We advise which technique fits your part.
Yes. We bend standard beams such as HEA, HEB and IPE, as well as tubes, channels, angles and custom sections. Which sizes and radii are possible depends on the profile.
