Galvanized Square Tube is a high-performance anti-corrosion structural steel tube, made of premium low-carbon steel with a hot-dip zinc coating and a regular square cross-section. Its square profile delivers exceptional structural stability, bending and torsion resistance for lightweight load-bearing applications, while the dense zinc coating provides reliable atmospheric corrosion and rust protection with strong adhesion. It features good weldability, formability and easy on-site installation, with complete specifications for customized cutting and processing. Cost-effective and durable, it’s a mainstream anti-corrosion structural tube for industrial, civil and municipal engineering projects.
