Overhead or industry doors are commonly used in large warehouses, industrial plants or production areas. Because of heavy usage and due to several weather conditions, the doors may become discoloured, damaged or tarnsished. Korthals’s coatings offer long-term protection for your overhead doors against all kinds of weather conditions and adhesion of dirt. During maintenance intervals, you can also count on Korthals’s coatings. Your overhead door will get a fresh, new appearance, to give your company the look and feel it deserves.

Due to our many years of experience, expertise and reliable quality your overhead door will look as good as new. Our unique Pro-Colour mixing system allows you to define your own choice of colors. This way, you’ll always get the perfect fit. Next to our varnishes and coatings for overhead doors, you can also rely on Korthals when it comes to expert technical assistance. We’d like to exchange ideas on how to coat your overhead doors.
