Brief Introduction of Corten Steel
Weathering steel, most famously known as COR-TEN steel and sometimes written directly as "Corten steel", is a group of alloy steel which can form a stable rust-like appearance if exposed to the weather for several years. And this kind of dense, tight layer of rust appearance will prevent the steel from rusting any further.

weathering steel is a kind of alloy steel between carbon steel and stainless steel,because the addition of Cu, Ni, Cr and other alloy chemical elements, weathering steel has excellent character of anti-corrosion. While the alloy percentage is small, so the price of weathering steel is much cheaper than stainless steel.

Weathering steel also has the advantages in ductility, molding, cutting, welding, and heat-resistant and abrasion resistance. Its weather ability is 5-8 time of carbon steel, and the paint ability is 1.5-10 times of the carbon steel.

Though this material will rust on its own if left exposed to the weather, it takes too long time to develop the stable rusty layer in nature and greatly affects the using of the weathering steel, especially the dropping of rust liquid and the flying of rust slag at the beginning of bare using. Then pre-rusted treatment becomes urgently demanded.

The size of Corten Steel size
 
Available size range of weathering steel:
Steel coil: thickness: 0.5-20mm width: 600-2000mm
Steel plates:
thickness:6-150mm
width: 1500-3800mm
length: max 27000mm
We can not only supply the common grades Q235HN, Q355NH, Q355GNH but also can produce the weathering steel according to EN, JIS and ASTM standard. Such as S355J0W, S355J2W, S355K2W, S355J0WP and S355J2WP according to EN10025-5:2004, SMA400AW/BW/CW, SAM490AW/BW/CW/, SAM570W/P according to JIS G3114-2004, container steel SPA-H according to JIS G3125-2004 and ASTM A588 Grade K.

There are also some other grades known by the high quality of the anti-corrosion ability and their excellent appearance after rusted. Such as 09CuPCrNi-A according to TB 1979
Service: pre-rusted treatment, bending, cutting, welding, profiling, punching and designing as the requirement.
Weathering steel is a great choice for a more modern, rustic look. Steel can be purchased in sheets, coils, pipes and sections.
