ASTM A242 A588 A606 09cupcrni-a Corten a Steel Sheet Durable

Corten steel, also called Weather Resistant steel or Atmospheric Corrosion Resistant steel, it is known as a low cost and highly effective material.

Corten steel is classed as being a "self -protecting "steel for its "patina "which results from protective surface oxidation and develops during exposure to the atmosphere; The oxide layer that gives the steel its distinctive appearance and enhances weather resistant capabilities compared to standard steels, also the improved corrosion performance can lead to improved service life.

The charcteristic for this steel: The surface will be rusted after somedays, but need to take some time around 3 Month; Also if you want it to be rusted very fast based on building requirement, we can do the rust processing too in our workshop,very good finish and the color can keep 3-5 years;

FAQ

01.What is special about Corten steel?

Corten Steel encompasses a group of steels which possess exceptional corrosion resistance and tensile strength. Corten Steel is also known as a 'weathering' steel; as the steel forms a protective layer on its surface under the influence of the weather, and it does not need to be painted.

02.Who invented Corten steel?

In the 1930's, U.S. Steel developed a commodity that they named Corten Steel. The product was originally designed to help build railroad coal wagons. The success of the coal wagons led to it being a prominent material for outdoor art projects during the 1960's.

03.How long will Corten steel last?

Generally, Corten steel will patina or rust within six months of atmospheric exposure. Most weathering steel types need wet/dry weather cycles to develop and oxidize. With the protective rust that provides corrosion resistance, Corten steel can last upwards of a few decades to over 100 years.

04.What is Corten steel made of?

Corten steel, often known as weathering steel, is a steel alloy recognised for its distinctive worn look and high durability. It is mostly made of iron, with trace quantities of copper, chromium, and nickel added to improve its weathering qualities.

05.Why is corten steel so expensive?

Corten steel is more expensive due to the materials used and the specialized production process. Traditional steel rusts and is therefore a less suitable choice for outdoor applications. Polyester is cheaper than corten steel, but does not withstand temperature changes as well and can become porous over time.
