DIN 17100 ST37/ST12/ST14/ST52 Carbon Steel Coil

ST37 steel coils are known for their excellent weldability and formability, making them ideal for structural applications. With a low carbon content, ST37 offers good tensile strength and is commonly used in the construction of buildings, bridges, and other infrastructure projects.
ST12 steel coils, on the other hand, are characterized by their exceptional ductility and malleability. This makes them perfect for deep drawing applications, such as automotive parts and household appliances. The smooth surface finish of ST12 steel coils also allows for easy painting and coating, enhancing their aesthetic appeal.
For applications requiring higher strength, our ST14 steel coils are an excellent choice. With improved mechanical properties, ST14 is suitable for manufacturing components that demand higher load-bearing capabilities. This steel grade is often utilized in the production of machinery, equipment, and structural components.
