Galvanized Rectangular Tube
Galvanized Rectangular Tube is a versatile anti-corrosion structural steel tube, made of high-quality low-carbon steel with a hot-dip zinc coating and a precise rectangular cross-section. Its oblong profile fits diverse load-bearing scenarios, offering excellent bending and torsion resistance as well as stable structural performance for lightweight fabrication. The dense zinc coating provides reliable atmospheric corrosion and rust protection with strong adhesion, paired with good weldability, formability and easy on-site installation. With complete specifications for customized cutting, it’s a cost-effective, durable mainstream anti-corrosion structural tube for industrial, civil and municipal engineering.
