When the result counts!


During its 30 years, Sias has established a signature that stands for good design and good craftsmanship. Through versatile assignments in steel, interiors, rehabilitation and ship conversions, we have established ourselves as a solid supplier in Eastern Norway.

Professionals with long, versatile experience and commitment exercise proper craftsmanship for the best possible solutions on the customer’s premises. Our employees also have extensive experience and good expertise in ship repairs and conversions. We have recently moved from Horten to Tønsberg in new, tailor-made premises in the central Barkåker Industri area.

Quality


Sooner or later it will always be clear whether the job is done well enough and we are happy that we have very good experience.
Over the years, we have carried out a number of assignments on land and at sea. Every project requires precise planning and customized solutions. Good cooperation with our customers and everyone involved is a large part of the job. In the planning phase, the foundations for an economical and efficient project are laid.

Thanks to our skilled professionals and subcontractors, who each have their own special areas, a guarantee of work carried out on time and at the right price is a matter of course. We can say that because we are confident in our capacity, competence and ability to deliver.

In our workshop, we can undertake work in steel, metal, brass, aluminum and stainless steel. We have a well-equipped workshop with processing equipment for plate, welding and thin plate.

Efficiency and accuracy characterize our production. Safety routines are followed and are part of everyday life. Well-equipped service vehicles ensure that we are also equipped for assembly outside the company.

Our service offer is broad. From the production of simple stairs and railings, to decorations in public spaces, trusses in large industrial buildings and the conversion and repairs of ships, and the production of components for industry.
