From design to finished part
Large diameters, thick walls and tight tolerances. For energy, offshore and industrial projects we roll plate into cylinders and cones, press brake where needed and weld the sections into tubulars that perform under the toughest conditions.
Co-engineering from the first design
We review your drawings early, from wall thickness to weld preparation, so the part can be rolled and welded as efficiently as possible.
Plate rolling for cylinders and cones
Plate rolling shapes steel into cylinders, cans and cones in large diameters. Press braking adds the shapes that rolling alone cannot reach.
Plate cutting and welding
We cut plate to size and prepare the edges, then weld rolled sections into tubulars and transition pieces to the standard your project requires.
Heat and surface treatment
Where your project calls for it, heat and surface treatment prepare the part for its environment.
When customers come to us
“We need J-tubes for an offshore wind farm, welded to EN 1090 EXC4.”
We bend, roll and weld J-tubes to the standard your project requires.
“We’re looking for a partner who can roll large cones and cans for a jacket foundation.”
We roll plate into large cones and cans and weld them into sections.
“Our project needs thick-walled steel cylinders with tight tolerances.”
Plate rolling and controlled welding keep large diameters in tolerance.

Frequently asked questions
That depends on the diameter and the steel grade: the smaller the diameter, the lower the maximum thickness. The capacity sheet shows the full range; for anything close to the limit, send us your drawing and we will check it.
Yes. Besides cylinders and cans, we roll plate into cones and transition pieces, as used in offshore foundations and industrial installations. We cut the plate to its developed shape, roll it and weld the seam, so the cone fits the adjoining sections.
We are certified to EN 1090-2 EXC4 and EN 1090-3 EXC3 for structural work and to EN ISO 3834-2 for welding quality. For pressure equipment we work to AD2000 HP0.
