Hot-dipped galvanized steel sheets are excellent candidate for most processing techniques. Welding, torching, or abrasive sawing galvanized steel is not recommended without proper protection and adequate ventilation. Galvanized hot rolled steel, or mild steel, sheets have been dipped into a molten zinc coating, or zinc-iron alloy-coated (galvannealed) by the hot-dipped process (ASTM A653). 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 HVAC, flashing, freezers, commercial and architectural uses, electrical boxes, enclosures and housings.
