Technical Parameters

COR-TEN Weathering Steel Plate

Corten steel, which is corrosion-resistant and protective, can be used on the exterior of buildings to eliminate the need for protective paint. Once the "rust film" is created, it resists corrosion for 80 years without the need for protective paint.

The main technical support for weathering steel panels to be used as façade materials is the superior corrosion resistance of weathering steel compared to ordinary steel. In the natural climate, steel corrosion thinning 5 years up to 0.1 ~ 1mm or more, a long time or in special and man-made harsh environments, thinning is more serious. And weathering steel (WISCO products, for example) by adding copper, chromium, nickel and other weathering elements, so that the steel material in the rust layer and the substrate between the formation of a layer of about 50 ~ 100μm thick dense and good adhesion with the base metal oxide layer. This special dense oxide layer has a stable and uniform natural rust red color.

weathered steel plate Products Details

Weathering steel (i.e., atmospheric corrosion-resistant steel) is between ordinary steel and stainless steel low alloy steel series of cheap and beautiful, in the integration of modern metallurgy, new mechanisms, new technologies and new processes to sustainable development and innovation, is one of the world's super-steel technology at the forefront of the level of the series of steel grades.

Weathering steel from plain carbon steel by adding a small amount of copper, chromium, nickel and other corrosion-resistant elements and become, with high-quality steel, plastic extension, forming, welding, abrasion, high temperature, fatigue and other characteristics; weathering for the plain carbon steel, 3 to 8 times, painting for the plain carbon steel, 1.5 to 10 times, can be used to thin the use of bare use or simplify the use of painting. The steel has rust-resistant, corrosion-resistant components to extend the life of the thinning consumption, labor-saving energy-saving features, so that component manufacturers, users benefit. For example, weathering steel bridges can save painting costs up to more than 10% of the construction investment.
