S235 Weathering Steel is a structural steel under the EN 10025-5 standard, known for its resistance to atmospheric corrosion. The “S” stands for structural, “235” is the minimum yield strength in MPa. It has good weldability, toughness, and durability in different climates, making it ideal for building facades, bridges, and outdoor structures. Similar grades are Q235C, SM400B, A283C.
Описание
What is S235？
S235 is a structural steel made of carbon and manganese, usually in solid, flat sheets or profiles. It offers good weldability, moderate strength, and toughness, ideal for construction, bridges, and engineering. Produced through hot rolling, it is available in untreated, normalized, or drawn forms, with variants like S235J0W and S235J2W. S235 classifications include JR, J0, and J2, indicating different levels of toughness and impact resistance.Why Choose S235 Weathering Steel?
For outdoor structures, reliable weathering steel is key. We recommend S235 Weathering Steel for its strong corrosion resistance and dependable performance. This steel naturally forms a rust layer, lowering maintenance needs and extending structure life. It’s easy to weld, with a balance of strength and flexibility, ideal for bridges, facades, and more. Choosing S235 helps you save on long-term costs, as it reduces repainting and repairs. Its moderate strength makes it versatile for various projects, and as a hot-rolled steel, it’s easy to handle in different forms. Plus, with options like S235J0W and S235J2W, you have choices to match different needs. S235 offers a great balance of weldability, toughness, and cost compared to other weathering steels. For tougher climates or high-load structures, consider alternatives like Corten A, Corten B, or A588 for higher corrosion resistance.Спецификация продукта
