Thabiso Steel is a reputable manufacturer and supplier located in Cape Town, South Africa, with a focus on high-performance S1100QL steel sheets and plates. These plates are engineered to provide exceptional strength and durability, making them perfect for demanding structural and load-bearing applications. Thabiso Steel is committed to delivering consistent product quality, precise cutting, and a superior surface finish that meets international standards. With state-of-the-art manufacturing facilities and a customer-centric approach, the company supplies S1100QL plates to a variety of industries, including construction, mining, heavy machinery, and transportation, offering both standard and customized specifications to fit specific project needs.
S1100QL steel plates and sheets are ultra-high-strength quenched and tempered structural steels with superior mechanical properties. They contain low carbon, high manganese, chromium, nickel, molybdenum, and vanadium to improve strength and toughness. With a minimum yield point of 1100 MPa and tensile strength of 1250-1400 MPa, S1100QL has superior durability and impact resistance. It has good weldability and formability while providing high wear and fatigue resistance. Suitable for heavy-duty use, S1100QL steel is extensively applied in construction, mining, and machinery that demands high strength and performance.

S1100QL steel plates and sheets are extensively applied in ultra-high strength, toughness, and durability demanding industries. Typical applications are in construction, heavy equipment, mining machinery, cranes, bridges, and structural parts subject to harsh loads. Their excellent yield strength (1100 MPa) and impact toughness make them suitable for the production of load-carrying structures, pressure vessels, and offshore platforms. Furthermore, S1100QL steel is applied in defense and military use for armored vehicles and protective buildings. With good weldability and formability, it provides reliability in severe conditions, and hence it is a choice for industries requiring high performance and long-lasting durability.
