Cold-rolled - Structural steel
Our structural steel is suitable for a wide range of applications.
It has a guaranteed minimum strength and offers good weldability for ease of processing.
Our advanced and ultra high-strength cold-rolled steels DP600, DP800, DP1000 and HQ1500 are lightweight and enable design freedom for complex parts.
Their high yield and ductility ensure shape accuracy and tolerancing, which enable thickness reduction and maintained in-service performance for difficult-to-form parts.
Cold-rolled structural steel has the following mechanical properties (skin-passed) - these are measured transverse to the rolling direction:
