ASTM A588 is a high-strength, low-alloy (HSLA) weathering steel specification known for its enhanced atmospheric corrosion resistance and high strength (minimum 50ksi yield strength). It naturally develops a protective, rust-colored patina over time, eliminating the need for painting and making it a cost-effective choice for structures like bridges, buildings, and outdoor art installations. This durable steel is suitable for various structural applications where strength, durability, and a maintenance-free finish are desired.

FAQ
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.
What kind of steel is Corten?
Corten or Weathering Steel is a version of low carbon steel that forms a thin layer of rust on the outside of the metal, thus preventing further corrosion. It is used for both its appearance and its corrosion protection.
What are the disadvantages of corten steel?
Another disadvantage of Corten steel is its susceptibility to rusting. Corten steel is designed to form a protective layer of rust on its surface, but it can break down over time, leaving the steel vulnerable to corrosion.
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.
How can you tell if steel is Corten?
Corten Steel undergoes a gradual weathering process so that you may notice signs of ageing, such as rust accumulation and colour changes over time. These visual cues indicate that the steel is indeed Corten and not a standard steel with surface rust.
