Welcome to Yoane Steel, your trusted partner for high-strength steel right here in the heart of Kinshasa. We take pride in being a leading manufacturer and supplier, bringing world-class materials like the exceptional S1300ql steel sheets and plates directly to our local industries. We understand the demanding projects built across Congo, and we are committed to providing the robust materials needed to ensure their success and longevity, strengthening our nation’s infrastructure one project at a time.
S1300ql steel is defined by a carefully balanced composition, often featuring precise levels of carbon, manganese, and micro-alloys like niobium and vanadium. This specific recipe gives it outstanding mechanical properties, most notably a minimum yield strength of 1300 MPa. This means it offers incredible resistance to deformation under immense stress, combined with excellent toughness. It’s a material built to handle extreme forces where failure is simply not an option.
