Corten Steel

Corten steel, also known as weathering steel, is a group of steel alloys that form a stable rust-like appearance after exposure to weather. This layer of rust acts as a protective barrier against further corrosion.

Corten steel works by developing a protective patina when exposed to the elements, via an oxidative process. This patina prevents further rusting and corrosion, making it ideal for outdoor use.

Yes, Corten steel is safe for garden use. It is commonly used for planters, garden sculptures, and other outdoor structures due to its durability and unique aesthetic.

The patina on Corten steel typically starts to develop within a few months of exposure to the elements and can take up to a few years to fully stabilise, depending on environmental conditions.

No special maintenance is required for Corten steel. The natural weathering process and patina formation protect the steel from further corrosion. However, occasional cleaning may be needed to remove debris or dirt.

During the initial weathering process, Corten steel can produce rust runoff, which may stain adjacent surfaces such as concrete or stone. This can be minimised by proper placement and using drainage solutions.

Yes, Corten steel is considered environmentally friendly because it does not require painting or other protective coatings, reducing the need for maintenance and chemical treatments.

Common uses include planters, garden edging, sculptures, fire pits, and water features. Its durability and aesthetic appeal make it a popular choice for outdoor garden products.

Corten steel is designed to withstand various weather conditions, including winter. However, ensuring proper drainage to prevent water accumulation is advisable to avoid potential rust runoff staining.
