Located in the vibrant industrial heart of Manama, Ahmer Steel has built a reputation as a trusted partner for high-strength steel solutions. We take pride in supplying top-tier S690 QL sheets and plates, materials engineered to meet the most stringent demands. Our commitment is to provide not just a product, but a reliable foundation for ambitious projects across the region, offering the exceptional durability and performance that modern construction and manufacturing require. You can count on us for quality that stands up to the toughest challenges.
The composition of S690 QL steel is carefully balanced with elements like carbon, manganese, and micro-alloys, which work in concert to deliver its remarkable strength. Following a precise Quenched and Tempered heat treatment, these sheets and plates achieve a minimum yield strength of 690 MPa, ensuring exceptional resistance to heavy loads and impacts. This high strength is coupled with good toughness, even in challenging environments, making it a robust and dependable choice where structural integrity is absolutely non-negotiable.
