Description

Hot-dipped galvanized perforated square tube 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 perforated square tubes are hot rolled steel, or mild steel, tubes that have been punched and 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 shelving, brackets, outdoor signs, and adjustable posts due to its telescoping size options.  Please see the available sizes table below for additional information on telescoping options.
