Marzouk Steel is a dependable manufacturer and supplier of S1100QL steel sheets and plates, serving clients from its base in Tunis, Tunisia. The company provides advanced high-strength steel solutions designed for demanding engineering and industrial applications. With a strong emphasis on quality assurance, modern processing methods, and adherence to international standards, Marzouk Steel delivers products that combine strength, reliability, and precision. Its technical expertise and efficient logistics enable customers to source S1100QL steel suitable for heavy-duty structures and high-performance projects across regional and global markets.
S1100QL steel sheets and plates are quenched and tempered fine-grain structural steels known for their exceptionally high strength. The chemical composition includes controlled levels of carbon, manganese, chromium, molybdenum, nickel, and boron, ensuring strength, toughness, and weldability. Mechanically, S1100QL offers a minimum yield strength of approximately 1100 MPa and high tensile strength, along with good impact resistance at low temperatures. These properties make the steel suitable for applications requiring extreme load-bearing capacity with reduced material thickness.

S1100QL steel sheets and plates are widely used in heavy engineering and high-stress structural applications. They are commonly applied in cranes, lifting equipment, heavy-duty vehicles, mining machinery, offshore structures, and high-performance construction components. The high strength-to-weight ratio allows designers to reduce overall structure weight while maintaining safety and durability. Due to its excellent mechanical performance and toughness, S1100QL steel is preferred in projects where reliability, efficiency, and resistance to extreme working conditions are critical.
