Product Details
What is weathering steel plate?
Weathering steel plate, also known as corten steel or COR-TEN steel, is a type of alloy steel that naturally develops a rust-like coating when exposed to various atmospheric conditions. This rust-like coating protects the steel from further corrosion and serves as a protective barrier. Weathering steel is commonly used for outdoor structures such as bridges and buildings.
Corten steel, also known as weathering steel, is a special steel originally developed for bridge building and skyscraper construction due to its incredible strength. It develops a protective rust-like coating when exposed to the elements, protecting the steel beneath. It has since been used for a variety of applications, from fencing to garden furniture.
What’s the application of weathering steel plates?
Weathering steel plates are used in a wide variety of applications, including bridges, railcars, buildings, transmission towers, sculptures, and industrial and agricultural equipment. The unique properties of weathering steel make it an ideal material for many outdoor applications, especially in areas with high humidity, salt spray, and other corrosive elements. Weathering steel is also used for facades, roofing, and siding in both residential and commercial buildings.
What’s the Advantages of weathering steel plates?
1. Weathering steel is highly corrosion resistant, making it an ideal choice for outdoor structures.
2. It is extremely durable, withstanding years of exposure to the elements without requiring additional protection.
3. Weathering steel has a unique aesthetic, creating a beautiful patina that can add character and charm to any outdoor space.
4. It is low maintenance, requiring little to no upkeep.
5. Weathering steel is an environmentally friendly option, as it is made from recycled materials and can be recycled again at the end of its life.
Corten steel avoids the volatile organic compounds from painting and the disposal of blast-cleaning debris from maintenance work in the future.
