Customer Testimonials


For the construction of our offshore wind farms, we need reliable partners and suppliers who not only understand our quality requirements but also know how to implement them.

That is why we have been working with Jan Wrede and his team for many years. He has supplied sophisticated structural components and complex lifting equipment for our projects.

We particularly appreciate the commitment of his team when it comes to delivering good solutions for time-critical problem cases quickly and professionally.
