What is a Cowden board

Cauden plate is made of ordinary steel by adding a little copper, chromium, phosphorus and other elements, and by special treatment. Its weather resistance and corrosion resistance is three to eight times higher than ordinary steel. According to different types and uses, CORTEN-A can be divided into four kinds: COR-TEN A (weather resistance and corrosion resistance performance is better than ordinary steel five to eight times), COR-TEN B (four times), COR-TEN C, COR-TEN B-Qt. Widely used in the production of train carriages, containers and Bridges; Weathering steel is used as building facade material, in North America, Western Europe, Australia and Asia in Japan, South Korea have a certain history. The earliest example is the Chicago Civic Center, completed in 1965. Different stages have different colors, if you need to buy, please pay attention to the authenticity.

features

• Weather resistant coating. Because cor-Ten is weather-resistant, it can be used without any coating. It not only reduces recoat cost and provides long film life, but also provides a stable color appearance with rust protection.

• Weldable. Welding can be easily done using any method such as manual or submerged arc welding, spot welding can also be used for thin materials.

• Can be processed. Can be cold working, hot working and gas cutting like Pugang, with the same strength grade.

• Rust aging in the early use of light yellow, slowly become reddish-brown. Then, when it's in the environment, the color changes to a steady dark brown in a year or two. Then again, the color changes very little, but only a dark brown.

The different stages

• Outdoor 1-3 months a stage, grow small rust, pugang rust point is loose, part of the rust treatment is poor and even rust skin;

• In the second stage of 4-8 months outdoors, the rust water is less, and the rust spots are smaller and thicker. Pugang rust water is more, the rust point is larger thin sparse; Ordinary steel plate rust column, tear marks are more serious, the bottom of the workpiece has black signs;

• In the third stage, there is a clear and dense rust core layer, which is closely adhered to form a protective layer, and it is almost impossible to remove rust by hand. Ordinary steel plate rust more, even the whole piece of rust peeling, rust red weathering board, rust wear. Cowden plate is inclined to reddish brown, ordinary steel plate is inclined to dark color.

Interesting use of the Cowden board

• Construction industry, building structures, Bridges, cranes for assembling items, freight industry (bulk cargo transport, tanks and containers), railway and road vehicles and exhaust systems.

• Art and architecture: Antony Gormley's Sculpture of the Angel of the North, familiar to Britons, continues to be beautiful but safe.

• 21㎡ micro-home in outdoor Lithuanian garage that retains strength and becomes more beautiful after use: garden sculpture and centerpiece.

• Long lasting, low maintenance functional outdoor products. Includes lighting and water features, indoor and outdoor wood storage and storage seating, weather-resistant steel flower basins, outdoor log burners and lawn edges, wall panels and partitions, garden stairs,

How to distinguish the true and false of cowden board?

• Naked eyes can not distinguish between the calden plate and ordinary hot rolled steel plate in the stage of immature rust. At this time the need for steel warranty, so as to avoid the business with bad filling, as far as possible to ask suppliers to provide steel red chapter of the original.

• At any stage, samples can be provided to a professional third party testing organization to test whether the metal composition matches the warranty.
