Protective coating

Protective coating

On a daily basis, industrial objects such as steel structures of bridges, drilling rigs or water barriers are exposed to various external influences, such as wind, water, cold weather, heat, chemical substances and other extreme circumstances. As a consequence, this may lead to corrosion and other types of wear and tear. Korthals’s protective coatings protect all kinds of surfaces and are designed for use under the most extreme conditions. This way their service life will also be considerably extended.

Due to our many years of experience and reliable quality your part will look brand new again. 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, you can also rely on Korthals when it comes to expert technical assistance. We’d like to exchange ideas on possibilities with regard to protective coatings.
