Gunmetal
Gunmetal is our standard finish, and is mild steel, dark anthracite in colour. Before it leaves our factory, we oil treat it to protect it. Treat it like a wok, and if any surface rusts appears, rub it down and apply any vegetable oil to protect as and when is needed. If kept under cover, should be trouble free.
Can my Gunmetal be left outside year-round?
Yes, our grills are designed to be outside all year round, with autumn and winter being our favourite times of year for wood-fire cooking. When not in use, put the cover on.
How does my Gunmetal grill weather?
Your Gunmetal Grill base is raw steel, so if left untreated it will gain a rusty patina over time. For this reason, we pre-oil your Gunmetal Grill with rapeseed oil for protection so you just need to add fire to finish the seasoning process off - just like seasoning a wok or cast-iron pan.
Long-term you have two options:
Option 1: Keep seasoning your Gunmetal grill and keep covered when not in use. The ember maker will need a quick coating of rapeseed oil after each cook due to the heat in this area, whereas the rest of the grill will just need doing when needed.
Option 2: Let it weather naturally and develop its own patina over time. The thickness of the raw steel base means it will last 10 years without any issues.
Cor-Ten
Put simply, Cor-Ten steel (also written as corten or COR-TEN®) is a type of high-strength, low-alloy structural steel renowned for its resistance to abrasion and corrosion. Originally developed by United States Steel in the 1930s, it was initially used in the shipping industry for constructing durable shipping containers.
What sets Cor-Ten steel apart is its unique weathering properties. When exposed to the elements, it forms a protective rust-like patina on its surface. This distinctive layer not only gives the material its striking, industrial appearance but also prevents further corrosion, making it incredibly durable and long-lasting.
Why Choose Cor-Ten Steel?
- Durability: Cor-Ten steel is built to last, with a lifespan of 25+ years. The weathered surface protects the steel beneath, ensuring structural integrity over decades.
- Low Maintenance: Unlike traditional steel, the rust patina eliminates the need for painting or additional treatments, offering a truly maintenance-free solution.
- Aesthetic Appeal: Its evolving patina creates a rustic, industrial look that enhances outdoor spaces.
- Weather Resistance: Designed for outdoor use, Cor-Ten steel can withstand year-round exposure to the elements without compromising performance.
Fun Fact: The UK’s most notable Cor-Ten structure is the iconic Angel of the North, which beautifully showcases the material's strength and aesthetic qualities.
