Quality, function, performance and safety permeate our design and manufacturing processes of pressure-bearing devices and steel building structures as well as lifting equipment. Our cutting-edge expertise allows us to design, manufacture, control, test and document advanced welded constructions in those in carbon steel materials and stainless steel material combinations that meet the most comprehensive requirements specifications and demanding environments from our customers.


We are certified in third part by accredited certification bodies for welding with associated processes according to SS-EN ISO 3834–2: 2005 and for steel constructions and load-bearing constructions according to SS-EN 1090–1: 2009 and FPC systems (Factory Production Control) in design class EXC 1-3.

  • We CE mark load-bearing components and steel building structures according to SS-EN 1090–1 EXC 1-3
  • We CE mark pressure-bearing devices according to PED AFS 2016: 1 (2014/68/EU) Module G
  • We CE mark lifting equipment and lifting devices according to SS-EN 13155 and MD 2006/42/EC
