Corten Steel is a special steel originally developed for bridge building and skyscraper construction due to its incredible strength. It develops a protective rust appearance on exposure to the weather, creating warm rich textures not always associated with metal.If this protective barrier is compromised, it will simply form a new skin to protect itself. Corten Steel is extremely durable and has a far higher resistance to atmospheric corrosion than other steels, making it is ideal for use in fire-pits, planters and water features. When you first receive your Corten Steel products they may arrive in an un-weathered or partly weathered or completely weathered condition. Once placed outside the weathering process will begin. This can take some time; Corten Steel has a reactive patina period of between 3 and 9 months depending on location and climate. The patina or rust acts as a protective barrier - it will not penetrate or compromise the structural integrity of the material. The colouration of each item will vary as the weathering process takes place, eventually producing a rusty brown patina.Stage 1 - Freshly manufactured Corten Steel. At this stage the dark oily residue coats the Corten Steel. Stage 2 - The oily residue is beginning to break down, as the Corten Steel begins to weather. Stage 3 & 4 - The "Run-Off" stage - This can take around 3-9 months depending on weather and positioning. Stage 5 & 6 - The final stages of the weathering process. Some "Run-Off" may still occur as the Corten Steels patina develops to a striking more consistent appearance.
Corten steel is widely used in garden screens, bridges, containers, facades, fire pit, BBQ, roadblock and sculptures with its long service, low maintenance cost and artistical patina.
Corten steel is between the ordinary steel and stainless steel cheap alloy steel series; outdoor corten steel decoration adopts new technology to sustainable development and innovation, and is becoming the world's top steel technology.
Corten steel tends to rust in the presence of humidity and air. Its rate depends on the speed at which oxygen, humidity and atmospheric pollutants enter the metal surface. As the process progresses, the rust layer forms a barrier for oxygen, water and pollutants to enter, and the rusting rate slows down. The rust layer formed on most common structural steels is porous. This kind of pore causes rust to fall off the metal surface after a certain period of time, which causes the corrosion cycle to start again.

As a low carbon steel, corten steel usually has less than 0.3% carbon by weight. This small amount of carbon keeps it tough and tough. Weatherproof steel also includes other alloying elements, which help to improve strength, but more importantly, corrosion resistance. Many different alloying elements are used, but the three key elements in weathering steel are nickel, copper and chromium.
