High Strength Steel Plate

High strength steels combine high yield strength, good ductility, and excellent weldability in one material.

Through TMCP (Thermo-Mechanically Controlled Process) or Q&T (Quenched & Tempered) treatment, these plates achieve optimized strength and impact resistance while enabling lighter structures and higher load-bearing capacity.

They are widely used in bridges, cranes, truck chassis, wind towers, offshore platforms, and heavy construction equipment, where both high strength and reliability are essential.

All high-strength steel plates are supplied with original Mill Test Certificates (MTCs) for full traceability by heat and batch number.

A. For ex-stock plates (especially heavy thicknesses), we can provide the MTC in advance so you can review chemical composition, mechanical properties, and Charpy impact values before confirming your order;

B. For cut-to-size orders, we will first send the MTC corresponding to the exact mother plate / heat number for your confirmation, and only proceed with cutting once verified. This ensures full transparency and customer satisfaction;

C. Every MTC is carefully verified against the markings on the original plate to ensure complete data accuracy and authenticity.

You are welcome to contact us to review sample MTCs of different grades and thicknesses before purchase, ensuring confidence and technical assurance in your selection.
