Företagets grundare och ägare Leif Kristensson har lämnat oss i stor saknad, vi kommer minnas alla fina stunder vi har haft tillsammans.

Vår verksamhet kommer att fortsätta bedrivas i Leifs anda.

Construction welding - Specialist in advanced welding contracts

With the entire Nordic market as our market, we carry out assignments in the petrochemical industry, the paper and pulp industry, power and heating plants, the pharmaceutical industry and the shipbuilding industry. In our well-equipped workshop, customized constructions are manufactured which we then assemble at our customers' premises.

Pipe systems, pressure vessels and cisterns. These are some examples of what we manufacture and assemble for our customers, all designs are adapted to the needs of each individual customer. All pre-fabrication is done in our well-equipped workshops. There is a large welding capacity and, among other things, profile rollers that can handle up to IPE500 beams, a 4 m wide, 400 ton press brake and a 3 meter wide miter saw for 25 mm sheet metal.
