What is Corten Steel?
Corten Steel (also known as weathered steel) is a category of steel alloys that are commonly used in outdoor construction. Corten Steel was designed to eliminate the need for painting, and if left outside and exposed to the elements, it will rust in a matter of months.
Cor-ten Steel Features
Weather Resistance : COR-TEN doesn't rust easily, so it doesn't need to be painted. Unpainted applications not only provide the economic benefit of lowering repainting costs, but they also provide aesthetic benefits due to the relaxing tone of the protective rust. While weather resistance varies depending on the product grade and application environment, COR-TEN has roughly 4-8 times the weather resistance of ordinary steel.
Paint Durability : COR-TEN can be painted just like regular steel. Also, even if there is a problem with the paint, COR-TEN stops the rust from spreading, which makes the paint last longer and saves money on repainting.
Weldability : Trace amounts of alloying elements like copper (Cu) and chromate (Cr) are added to COR-TEN to make it resistant to the weather, but the carbon content is lowered to make it easy to weld. So, COR-TEN can be welded by hand, with a gas shield, or with an arc that is submerged in a liquid. Thin-gauge COR-TEN can also be joined with spot welding.
Workability : COR-TEN is just as easy to work with as regular steels of the same strength. It can be bent, shaped, and cut with gas.
Reliability : Since "COR-TEN" started being sold in 1959, more than 2.6 million tonnes of it have been made.
