Prefabrication services
Wide flats from plate and strip
Wide flats from plate and strip are dimensionally accurate and ready for assembly. Wide flats speed up the manufacture of steel structures and avoid wasting of material.
Read more about cutting wide flats from plates and strip
Flat cut shapes
Flat cut shapes will decrease the throughput time of installation. The customer will receive the components ready for installation. So, unnecessary material and storing costs can be avoided. If ordered, the products are delivered as shop-primed, bevelled and bent.
Read more about flat cut shapes
Bevelling
Precision cut lengths and precision cut plates with a bevelled edge are components that can be delivered directly to the installation site, which saves time and reduces transport and storage costs. The dimensionally accurate groove ensures uninterrupted automated welding and fitting.
Read more about precision cut lengths and precision cut plates with bevelled edge
Bent plate products
Bent plate products are components that are ready to be delivered to the installation site, which is beneficial in terms of schedule as well as transport and storing costs. If needed, the products can be ordered as shop-primed, furnished with welding bevels, and cut to shape. Premarked matchmarks facilitate installation.

Processing instructions
All the shipbuilding steels and pressure vessel steels have good weldability. Bendability and other workshop properties correspond to those of structural steels of same strength class.

Order & delivery
Inspection document
In accordance with the regulations of the Classification Societies, a so called Mill Sheet and Test Certificate will be provided for shipbuilding steels. In this, materials testing results and chemical analyses results are presented. The nearest equivalent inspection document to this certificate in the EN 10204:2004 is the inspection certificate 3.2.
The inspection document for offshore steels (EN 10225) is in accordance with EN 10204 -3.1.
Offshore steels can also be delivered by the acceptance of the Classification Society.
