Weathering steel is just like Corten steel, with all the same qualities, but cheaper. This is because Corten is a brand name. Weathering steel sheets offer you the same great properties but at a lower price.

Please note: These sheets will come in their natural form and will weather over a period of 2 months – 3 years

If you’re looking for a cheaper alternative to Corten steel, weathering steel could be perfect for your project. Weathering steel possesses the same great properties as Corten steel, but as it doesn’t carry the brand name, it costs less. Just like Corten, weathering steel starts out blue-grey in colour and weathers to a rust-coloured finish. The orange patina protects the metal from corrosion and takes 6-9 months to develop.

Please note: these sheets will arrive in their natural form, ready to weather over a period of 6-9 months. If you need your steel to arrive with the orange coating already in place, see our pre-weathered Corten steel.

When weathering steel is exposed to the elements, it reacts with oxygen and moisture in the atmosphere, a process called oxidisation. When oxidisation occurs, the metal develops a distinctive orange coating, known as a patina. This exterior coating protects the internal steel. While the auburn-hue might look like rust, it doesn’t penetrate the steel, meaning the metal does not weaken or depreciate. With its good looks and lasting durability, weathering steel is a big hit with designers.

Weathering steel is a more affordable choice than Corten steel for a broad range of projects, including landscaping, art and architecture

We supply weathering steel panels in a huge variety of thicknesses and sizes and we can cut it to custom sizes, so you can just order what you need.

How it’s made:

Weathering steel is an alloy; the addition of nickel, copper and chromium at production means that as the steel is exposed to the elements it develops its protective patina.

Good for: External cladding, marine projects, architecture, water features, outdoor planters, sculptures, design features, signage.
