The products are made of Swedish pre-painted steel, GreenCoat RWS from SSAB. The steel core is hot dip galvanized with a self-repairing zinc layer. The surface is pre-painted with a high-built polyester coating that is developed to restrain bleaching from wind and sunshine. In this way the gutter will have a good corrosion resistance and will keep its aesthetic lustre during many years.
