Galvanized square & rectangular tubes are made of high-quality carbon steel coil, formed by cold bending, welded and then hot-dip galvanized.
The galvanized layer features strong adhesion, corrosion resistance, rustproof and long service life. With smooth surface, uniform zinc coating and good mechanical performance, they are widely used in construction framework, guardrail, engineering structure, pipeline support, warehouse shelf and steel structure projects.
We supply high-quality galvanized square and rectangular steel tubes with consistent galvanizing thickness and stable mechanical properties. Strict quality control ensures precise dimension tolerance and uniform surface quality. With abundant stock, customizable processing services and fast shipment, our galvanized hollow sections are highly recognized by clients from Europe, Southeast Asia, Middle East and other global markets.
