High Strength Steel

Hot Rolled – High Strength Low Alloy (HSLA) steel grades are a micro-alloy steel engineered to provide higher strength, good formability, weldability and durability. These products are extensively used in the manufacture of automotive parts by reducing steel thickness and weight whilst increasing the strength making them ideal for the most demanding applications.

These high-performance grades enhance productivity by increasing yield and streamlining processing, providing a material solution that supports innovation and efficiency in your projects.
