Carbon & High Strength Low Alloy (HSLA) Structural Steel Plate

Carbon & High Strength Low Alloy (HSLA) Structural Steel Plate

Leeco® Steel carries a deep inventory of carbon - or mild - steel plate as well as High Strength Low Alloy - or HSLA - steel plate. HSLA boasts a higher strength, lower weight and good machinability and ductility compared to conventional mild carbon steel grades.

HSLA structural steels are manufactured to meet specific mechanical properties, such as hardness, strength, corrosion resistance and environmental durability, making HSLA steels the ideal choice for structural construction including truck frames, brackets, crane booms, rail cars and other comparable applications. While certified HSLA steel grades have specific chemical compositions, engineers refer to HSLA mechanical properties over chemical composition when selecting material for a specific project.
