Yoane Steel is a reputable manufacturer and supplier located in Kinshasa, Democratic Republic of Congo, with a focus on producing top-notch Shipbuilding Steel Sheets and Plates. We pride ourselves on our dedication to precision engineering and adherence to international quality standards. Serving shipyards, marine contractors, and industrial fabricators throughout Africa, Yoane Steel delivers products that are built to withstand the tough demands of marine environments, ensuring they offer strength, durability, and resistance to corrosion. With cutting-edge manufacturing technology and a talented workforce, we provide dependable steel solutions that aid in the construction, repair, and maintenance of ships, offshore structures, and various heavy-duty maritime applications.
Our Shipbuilding Steel Sheets and Plates are primarily made from iron, blended with carefully controlled amounts of carbon, manganese, silicon, and trace elements like phosphorus and sulfur. Depending on the specific grade (such as AH36, DH36, EH36), these steels boast excellent weldability, impressive tensile strength (ranging from 400 to 550 MPa), and outstanding impact resistance. Their well-balanced chemical composition enhances toughness and helps prevent brittle fractures, even in colder temperatures. Through heat treatment and controlled rolling, we achieve a uniform grain structure that boosts overall mechanical performance for the rigorous demands of shipbuilding and offshore applications.
