Corten steel, also known as COR-TEN steel, has revolutionized outdoor grill design in recent years with its unique corrosion resistance and naturally rusted aesthetic. Due to its alloying properties (including copper, chromium, and nickel), this steel forms a stable rust layer in the natural environment. This steel requires no additional coating and, over time, develops a distinctive russet-brown texture, creating an artistic installation in any outdoor space.

Material Properties and Industry Trends
The core advantage of GNEE Corten Steel Grill Barbecue lies in their ability to resist rust. When exposed to wind and rain, a dense oxide layer (γ-FeOOH) gradually forms on the steel surface. This rust film prevents further corrosion of the underlying metal, extending its service life in outdoor environments by three to five times that of ordinary steel. Compared to traditional stainless steel grills, corten steel requires less maintenance; regular cleaning with a wire brush is all that's needed to maintain its performance.

Combining Aesthetics and Practicality
The ever-changing rust color of corten steel offers endless possibilities for outdoor design. By controlling the rust rate and surface treatment, the designers achieved a gradient effect from orange-red to dark brown, blending seamlessly with the natural landscape. This effect is fully reflected in the GNEE series of grills.

In addition, the GNEE team supports the application of different exterior paint colors on the GNEE Corten Steel Grill Barbecue to meet the aesthetic needs of different customers.

Environmental Protection and Sustainability
The production process of corten steel reduces the chemical pollution caused by traditional painting processes. It is 100% recyclable and complies with the EU RoHS Directive and China's Green Manufacturing Standards. Due to their low maintenance cost, corten steel grills are becoming the preferred choice for equipment upgrades in the catering industry.
