Operating out of the vibrant city of Kinshasa, Congo, Yoane Steel stands as a dependable partner for the nation’s construction and industrial growth. We specialize in supplying high-quality S355JR+N steel sheets and plates, essential materials known for their reliability and strength. Our presence in the heart of the region ensures that our clients receive the robust materials they need efficiently, supporting critical infrastructure projects and manufacturing ventures across the country with a commitment to quality and local service.
When you choose S355JR+N, you’re selecting a steel grade prized for its excellent balance of strength and workability. Its chemical composition includes controlled levels of carbon, manganese, and silicon, ensuring reliable performance. Mechanically, it offers a minimum yield strength of 355 MPa, providing substantial structural integrity. The “+N” designation signifies it has been normalized rolled, a process that enhances its toughness and makes it particularly well-suited for welding, a common requirement in demanding fabrication environments.
