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 galvanize (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.
