Roof coatings

Paint-coated steel sheet metal is an extremely durable building material, which can withstand flashing, various weather conditions as well as mechanical stress. The easy-to-care roof coating maintains its colour for a long time and when maintained well, it can last for decades. Metehe’s roof coating selection has several colour and coating options for finishing the building to suit its environment.

Paint-coated steel sheets are manufactured in accordance with the EN-10169-1 standard. To ensure the conformity between Colorcoat products, Tata Steel uses laboratory tests to test the products’ corrosion, UV radiation, chemical and wear resistance. All product tests are carried out in approved laboratories in accordance with international standards.
