How it all began

Roofing materials for the Czechoslovak market began to be produced by COMAX® in the 1970s. This was at a time when practically none of the existing well-known manufacturers of metal roofs were active in Czechoslovakia and, with the Scandinavian exceptions, did not even exist. COMAX® started its production with the aluminium roofing material ALUKRYT® and aluminium strips for folded roofs. Until 2014, we were based in the production facility of the parent company METAL TRADE COMAX, where we also served as the company's sales office.

Alukryt - 1973

Because of the growing demand, we decided to capitalize on our many years of experience in sheet metal processing and since 2015 we have been producing sheet metal roofing and all accessories under the brand name COMAX® ROOFING in a new modern 12,000 m² facility connecting the production, warehouse and showroom. We have successful dealerships in Bristol, England and Weißenhorn, Germany.

Experience in sheet metal painting, cutting-edge technology and precision manufacturing give our roofing products high quality and a lifetime guarantee of up to 75 years.The parent company METAL TRADE COMAX, a.s. is one of the first representatives of continuous sheet metal painting in Europe and the only manufacturer of painted sheet metal in the Czech Republic. The company is a member of the ECCA association, which brings together and educates the most important European sheet metal fabricators.
