What is Corten Steel?
Corten steel, often referred to as weathering steel, is a group of steel alloys designed to form a stable rust-like appearance after exposure to weather. The name “Corten” is derived from its two primary properties: corrosion resistance and tensile strength. This unique material eliminates the need for painting, making it a low-maintenance option for a variety of architectural applications.
What is Corten Steel Cladding?
Corten steel, or weathering steel, forms a protective rust-like patina on its surface, which resists atmospheric corrosion, making it durable and long-lasting. When used as cladding, corten steel covers building exteriors, offering several benefits. Its weather-resistant patina protects against further rusting, making it ideal for outdoor use. It requires minimal maintenance, perfect for hard-to-reach areas, and withstands harsh weather, ensuring long-term protection. Additionally, the rustic, industrial look of corten steel adds a distinctive, modern aesthetic to any structure. In summary, corten steel cladding is a durable, low-maintenance, and visually appealing choice for protecting buildings.
Advantages of Corten Steel Cladding
- Aesthetic Appeal: Corten steel’s rustic look adds a modern, industrial touch with an evolving color palette from orange to deep brown.
- Cost-Effective: Higher initial cost is offset by minimal maintenance and long-term durability.
- Versatility: Suitable for building facades, landscaping, public art, and interior design, offering a cohesive, striking appearance.
- Strength and Stability: High tensile strength supports significant loads, making it ideal for both structural and decorative uses.
Is Corten Steel Cladding Expensive?
Weathering steel cladding, also known as corten steel, can be three times more expensive than regular mild steel. This means that the initial cost for purchase and installation is quite high. However, because it requires less maintenance and is highly durable, the overall cost of corten steel cladding becomes more affordable over time. We offer corten steel cladding with thicknesses ranging from 1.0 to 1.5 mm, ideal for roofing and siding applications.
