Operating from the heart of Kinshasa, Yoane Steel has established itself as a trusted partner for industry, specializing in the supply of high-grade S355J2+N steel. We understand that the backbone of any major project is reliable materials, which is why we are committed to providing sheets and plates that meet rigorous international standards. Our focus is on supporting the growth of Congo’s infrastructure and manufacturing sectors with quality steel you can count on, delivered with the local expertise and service our clients deserve.
The S355J2+N grade is a high-strength, low-alloy steel known for its excellent balance of durability and formability. Its chemical composition includes carefully controlled levels of carbon, manganese, and other elements, which contribute to its robust nature. After a normalization rolling process, it achieves impressive mechanical properties, including a minimum yield strength of 355 MPa. This ensures it can handle significant stress and impact, making it a tough and reliable choice for demanding structural work where safety is paramount.
