Ductile and High-Strength Low Alloy (HSLA) Steel Plates

High-Strength Low Alloy (HSLA) steel plates offer better environmental corrosion resistance and are more robust than convention carbon steel. HSLA is also extremely ductile, easy to weld, and highly formable. HSLA steels are not usually made to meet a specific chemical composition instead they are known to meet precise mechanical properties. The HSLA specification is meant primarily for use in structural members, where savings in weight and added durability are crucial.

Leeco Steel stocks a wide-ranging supply of HSLA steel plates in different grades that match both Canadian and the US standards. HSLA can be used in brackets, rail cars, truck frames, crane booms, and other comparable applications.
