S690Q High Tensile Steel Sheet
S690Q high strength steel plate is a high yield structural steel produced in compliance with EN standards. The material is heat treated using a quenching and tempering process and has good bending and welding properties. Due to the material's high-strength properties, using S690Q high yield strength steel plate allows for a leaner design, improving payload capacity and energy efficiency.
Known for its high strength, S690Q structural seel plate is widely used in engineering fields with high strength requirements, including cranes, critical structural components in buildings and sports venues, and pipes and gates in hydropower projects.
