What is CorTen steel sheet and what is it used for?
We offer CorTen sheet metal in 1.5mm, 2mm, and 3mm thicknesses and in standard sheet sizes up to 2500mm x 1250mm. We also supply pieces cut to your required dimensions; simply enter your measurements into the custom size box on the product page when ordering online and we will do the hard work for you. All our CorTen plate stock is cut square on our fully automated guillotine.
CorTen is a general name for 'Weathering steel'; a material which forms a stable rust-like appearance after exposure to weather that was developed to be resistant to corrosion and to not need regular maintenance or painting.
Cor Ten is a mixture of different kinds of steel (alloy) and has mechanical properties that are both resistant to corrosion and very strong. The name, CorTen, is a portmanteau of "Corrosion" and "Tensile" indicating a material that is resistant to corrosion and which has a high tensile strength (resistance to breaking under tension). CorTen has excellent machinability and good weldability and formability.
During the weathering process, CorTen's appearance changes until the surface eventually evolves into an orange, or brown, oxidised, rust-like appearance which is unique and distinctive; this stable surface eliminates the need for painting or weatherproofing so is perfect for low-maintenance applications.
CorTen is used in architectural applications and external cladding for buildings and is also popular with artists and sculptors and has been featured in many popular works of art, for example,it was used to create Antony Gormley's 'The Angel of the North' in Gateshead.
CorTen steel sheet is supplied 'un-weathered' and will take several months to reach its stable orange brown finish, therefore, the metal you buy may well differ at first from the image shown. The weathering process is accelerated by atmospheric pollutants so weathering of CorTen will be faster in cities, urban areas, and coastal locations than out in the countryside.

FAQs
-
Is Corten steel expensive?
Corten steel, also known as ‘weathering steel’, tends to be more expensive than other types of steel. However, its unique properties and long-term benefits often make it a cost-effective choice. The durability and minimal maintenance required can reduce overall expenses over time, making it a wise investment for projects where weather resistance and aesthetic appeal are essential.
-
What are the advantages of Corten steel?
Corten steel is widely appreciated for its range of benefits:
- Weather resistant: Corten steel forms a stable rust-like appearance when exposed to general weather conditions, moisture, sunlight, and air pollution, which acts as a protective layer and prevents further corrosion.
- Low maintenance: Once the protective oxide layer or ‘patina’ has formed, Corten steel requires minimal upkeep, making it an excellent choice for outdoor applications.
- Environmentally Friendly: Corten steel is fully recyclable, and its long lifespan reduces the need to replace it, contributing to sustainable practices.
- Longevity: Corten steel is designed to withstand harsh environments, ensuring that structures and designs maintain their structural and aesthetic integrity for decades.
-
Does corten steel need to be sealed?
Corten steel does not require sealing because it naturally develops a protective rust patina that safeguards it from further corrosion. However, in some situations, sealing can be beneficial. For example, if you want to prevent staining or ensure additional protection in particularly harsh or marine environments; products such as polyurethane or other coatings that contain antioxidants to prevent tarnish, oxidation, and corrosion can seal the surface
