Products Description
S690QL high-yield structural steel plate is a high-yield structural steel grade produced in compliance with EN 10025-6:2004. The material undergoes quenching and tempering heat treatment, providing excellent bending and welding properties.
Due to its high strength, using S690QL allows for leaner, lighter structures while maintaining or improving load-bearing capacity. This is particularly beneficial for mobile applications, where it increases payload capacity and operational efficiency, as well as for fixed steel structures.
The designation S690QL refers to a minimum yield strength of 690 MPa. Its combination of high strength, good availability, reasonable pricing, and ease of fabrication has made it a popular choice for a wide range of applications, including cranes, lifting equipment, and other structural components.
