We take pride in offering top-notch structural steel products that cater to a variety of applications. Our S355JO+N steel is crafted in line with international standards, recognized for its impressive strength, excellent weldability, and long-lasting durability. The “+N” signifies that the steel has undergone normalized rolling, which boosts its toughness and uniformity, ensuring it performs consistently. At Yousef Steel, we prioritize quality, dependability, and prompt delivery, making our S355JO+N sheets and plates the go-to choice for construction, infrastructure, heavy engineering, and industrial projects both in Saudi Arabia and beyond.
S355JO+N Steel Sheets and Plates are low-carbon, high-strength structural steels that contain controlled amounts of carbon, manganese, silicon, phosphorus, and sulfur. They offer a minimum yield strength of 355 MPa and tensile strength that ranges from 470 to 630 MPa. The “JO” designation signifies an impact energy of 27J at 0°C, ensuring toughness even in freezing conditions. The normalized (+N) state enhances uniformity and mechanical stability. With outstanding weldability, machinability, and formability, S355JO+N plates provide reliable performance in demanding structural applications where durability and safety are paramount.
