We have a long and proud history

Our group of companies are all based on the same values which have characterized W. Giertsen for more than 140 years. Deep understanding of customer needs leads us to solutions in which we combine robust engineering with practical workmanship.

A case in point is the journey from sailmakers, to industrial halls that later were mounted with solar panels thus entering the expanding market of renewable energy.
