Corten steel plate is a steel that Weather resistant structural steel. The anti-corrosive properties of weather resistant steel are better than those of other structural steels in many applications. The steel is self-protecting: the rust layer on the surface becomes a tight oxide layer that slows down the progress of corrosion.
Weathering steel is a copper chromium alloy which is 'self-healing'. The untreated steel reacts to
chemicals in the atmosphere as part of the oxidation process and generates its own protective
layer of rust. This layer (or patina) prevents the steel from further deterioration and replenishes itself over time.
The plate is used in truck frames, brackets, crane booms, rail cars, and other comparable applications.
Application
Construction, building, outside wall, railway, containers, etc.
