For applications such as construction materials and bridge repairs! Not only thick plates but also shaped steel that is rich in weather resistance.

"COR-TEN" is a weather-resistant steel plate that protects the base material with its surface rust and suppresses the progression of rust. With excellent weather resistance, paintability, and weldability, it features a subdued color tone of rust that enhances its aesthetic effect. This steel material has the characteristic of preventing rust with rust itself. We offer a wide variety of shape steel, including channel steel, H-beams, flat steel, and angle steel. Please feel free to consult us when you need assistance. 【Features】 ■ Reduces the weight of steel material due to high strength at room and high temperatures ■ Can be used unpainted due to excellent weather resistance ■ Reduces repainting costs, lowering lifecycle costs and environmental impact ■ Enhances aesthetic effect with the subdued color tone of protective rust ■ Easily weldable by any method, including manual welding *For more details, please refer to the PDF document or feel free to contact us.
