A Corten steel outdoor barbecue will last for many years. Standard models, which are 2–3 mm thick, will typically last 25 years or more. If you want something very strong, choose units that are 4 mm or more, as these can last for 40 years, even a century if they are in perfect condition.

How long a Corten steel outdoor barbecue lasts depends on two things: how thick the steel is and how much it is exposed to the environment. Its natural protective layer stops it from getting any worse.

Factors Shaping Lifespan

Steel thickness: Thicker panels make them last longer. A 3 mm Corten steel outdoor barbecue will last for more than 25 years, and adding just 1 mm of thickness will reduce wear and extend the lifespan to over 40 years.

The things that affect it: The protective layer can be eroded by high salt levels, which can shorten the lifespan compared to mild, inland climates.

Maintenance: Corten steel doesn't need much looking after, but if you clean it once a year with a stiff brush to get rid of any dirt or debris, it'll help to keep the rust layer intact. This means your barbecue will stay strong for longer.

Key advantages of Corten steel for outdoor barbecues:

Unmatched durability: The surface is naturally resistant to corrosion, so it's perfect for outdoor use all year round.

Easy to look after: You don't need to repaint or use special coatings—the rust layer protects the surface by itself.

Timeless Aesthetics: The colour is a rich rust, which makes it look stylish and rustic. It will suit any garden or patio.
