Weathering steel, that is, atmospheric corrosion resistant steel, is a low alloy steel series between ordinary steel and stainless steel. Weathering steel is made of ordinary carbon steel with a small amount of copper, nickel and other corrosion resistant elements. It has the characteristics of high quality steel, such as strength, plastic casting, forming, welding, abrasion, high temperature and fatigue resistance.The weatherability is 2~8 times that of normal carbon steel, and the coating ability is 1.5~10 times that of normal carbon steel.At the same time, it has the characteristics of rust resistance, corrosion resistance, life extension, thinning and energy saving.
Corten Steel, which originated in North America, is widely used in the manufacture of railway carriages, containers and Bridges.Corten steel has a history of being used for building facades in North America, Western Europe, Australia and Asia, including Japan and South Korea.By adding weather resistant elements such as copper, chromium, nickel, etc., weatherproof steel can form a compact oxide layer with a thickness of about 50 ~ 100 m between rust layer and matrix and a good adhesion to matrix metal.This special dense oxide layer has a stable and uniform natural rust red color.
1.Unique performance characteristics: First, it has outstanding visual expression.Corroded steel plates will change over time.Its color lightness and saturation is higher than that of ordinary construction materials, so it is easy to stand out in the background of garden plants.In addition, the rough surface caused by the corrosion of steel plate makes the structure more volume and quality.
2.It has a strong body shaping ability.Like other metals, corroded steel is easier to shape into a rich variety of shapes and retains an excellent integrity that is difficult to achieve with wood, stone or concrete.
3. It also has a distinct ability to define space.Due to the great strength and toughness of steel plates, the thickness limit caused by structure is not as great as that of masonry materials.Therefore, very thin steel plates can be used to separate the space very clearly and accurately, so that the site becomes concise and lively, and full of power.
