SS400/SS490/SS540 Galvanized square pipe
SS400: This is a common structural steel with good weldability and formability. Its yield strength and tensile strength are moderate and suitable for general structural purposes. SS490: This steel is stronger than SS400 and is suitable for structures that require higher strength and durability. It also has good weldability and formability. SS540: This is a high-strength structural steel with higher yield strength and tensile strength and is suitable for structures that require extremely high strength and durability.
