Operating from the heart of Kinshasa, Yoane Steel has established itself as a trusted partner for the nation’s most demanding industrial projects. As a leading manufacturer and supplier, we specialize in providing high-strength S890QL steel sheets and plates, materials engineered to meet the rigorous challenges of the modern construction and engineering landscape. We understand that the strength of your project begins with the quality of its core materials, which is why we are committed to delivering superior products that form the resilient backbone of Congo’s growing infrastructure.
The exceptional strength of S890QL steel comes from a carefully balanced composition that includes elements like carbon, manganese, and chromium, enhanced by a specialized Quenched and Laminated heat treatment. This process gives the material a remarkable minimum yield strength of 890 MPa, along with impressive toughness and good weldability. Essentially, this means the steel offers an outstanding strength-to-weight ratio, allowing for the creation of lighter, yet far more robust and durable structures that can withstand significant stress and impact.
