Introduction
The anticorrosive properties of weather-resistant steels are better than those of other structural steels in many applications. The enhanced weather resistance is based on the oxide layer, i.e. patina. The use of uncoated weather-resistant steel in steel structures saves surface treatment costs. The elegantly brown patinated surface is architecturally distinguished. The patina-type surface can be obtained in weather-resistant steels using Rust Brown method, which extends the scope of application of weather-resistant steels to indoor structures. Weather-resistant steel in flue gas structures prolongs the service life of chimneys and flue gas ducts. The panels shown in the image above were manufactured by EDM Spanwall Facades with the COR-TEN® supplied by Glen Metals.
