Galvanized square steel tube is easy to weld, cut, form and machine. The galvanized coating also allows for improved corrosion resistance over other types of carbon steels. In addition, galvanized tubes are a lower cost alternative to steel to achieve rust free protection for up to 30 years, while maintaining comparable strength with a durable surface coating.


Hot-dipped galvanized square tubing is an excellent candidate for most processing techniques. Welding, torching, or abrasive sawing galvanized steel is not recommended without proper protection and adequate ventilation. Galvanized square tubes are hot rolled steel, or mild steel, tubes that have dipped into a molten zinc coating process. Hot-dipped galvanized (HDG) can be identified by its crystallization pattern, also known as "spangle" on the surface of the material. Great corrosion resistance, excellent candidate for outdoor use or exposed environments. Common applications include structural support, outdoor signs, docks, trailers, sign posts and framing.
