Corten Sheet Metal
It is a type of weathering steel, or corten steel, that is specially designed to form a stable rust-like appearance when exposed to the weather. Corten Sheet Metal has a high-strength, low-alloy (HSLA) composition that makes it suitable for outdoor projects, such as landscaping, roofing, siding, and art.

Chemical Composition
Corten Sheet Metal has a complex chemical composition, which consists of iron, carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, copper, and vanadium. The addition of these elements enhances the corrosion resistance and mechanical properties. The following table shows the chemical composition, according to ASTM A606-4 standard.

Application Areas
Corten Sheet Metal is widely used for various outdoor projects, such as landscaping, roofing, siding, and art. It can withstand harsh weather conditions, such as rain, snow, wind, and sun, and form a beautiful and natural rust-like appearance that blends with the environment. It can also reduce the maintenance and repair costs, compared to other conventional metals. Some examples of projects that use are:
- Landscaping: Be used for making the edging, fencing, retaining walls, planters, and sculptures for your garden, patio, or lawn. Corten Steel Sheets can create a unique and artistic look for your landscaping, by forming a natural patina over time.
- Roofing: Be used for making the roofing panels, flashing, and trim for your house, barn, or shed. Corten Steel Sheets can provide a durable and weather-resistant roof, that can also add a rustic and natural charm to your building.
- Siding: Be used for making the siding panels, cladding, and fascia for your house, garage, or workshop. Corten Steel Sheets can provide a strong and corrosion-resistant siding, that can also create a distinctive and attractive look for your building.

Selling Points
Corten Sheet Metal has many advantages and benefits that make it an attractive choice for customers. Some of the selling points are:
- High strength and low alloy: It has a high strength-to-weight ratio, which means it can provide more strength with less weight. This can reduce the material and fabrication costs, as well as the transportation and installation costs. Plate A516 Gr 70 also has a low alloy content, which means it has less impurities and better weldability and machinability.
- Weathering and corrosion resistance: It has a special weathering ability, which means it can form a protective layer of rust on its surface when exposed to the weather. This can enhance its corrosion resistance and durability, as well as its aesthetic value. Plate A516 Gr 70 also has a high resistance to atmospheric corrosion, which means it can withstand the effects of rain, snow, wind, and sun, and maintain its appearance and performance for a long time.
- Versatility and compatibility: It can be used for various outdoor projects, and can be compatible with other materials, such as wood, stone, and metal. Corten Steel Sheets can be fabricated into different shapes and sizes, according to the design and specification of the customers. Plate A516 Gr 70 can also be coated or painted, to change its color or appearance, according to the customer's preference.
