Henan Doing is a professional manufacturer focusing on the corten steel raw material supply, designing, processing, Surface treatment, Post-weld installation and construction. Also providing overhaul, maintenance and so on after-sales service. In a word, we offer you with comprehensive processing plan for weather resistant steel.
Weathering steel is a kind of low alloy high strength steel with some alloying elements and good corrosive properties. That is not Stainless steel, It is also corroded as common carbon steel During initial period. Some time later, Cu, P and other trace elements enrichment, forming a layer of dense amorphous rust layer of tissue. This tissue could prevent further corrosion of steel to some extent. the rust layer will become stable, forming chocolate color on the steel surface, very solid with the matrix. To prevent further corrosion of the base metal. The property of Corten-A is 5~8 times as high as common steel. COR-TEN B is 4 times as high as common steel. Characteristic: Good corrosion resistance, low cost, no need coating, save labor and environmental protection,sustainable use.
