Hot-dipped galvanized round bar 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 round bars are A36 hot rolled steel, or mild steel, round bars that have been dipped into a molten zinc coating process (ASTM A123). Hot-dipped galvanize (HDG) can be identified by its crystallization pattern, also known as “spangle” on the surface of the material. Galvanized round bars are semi-rough with dull edges, and are inexact dimensions throughout length. Great corrosion resistance, excellent candidate for outdoor use or exposed environments. Common applications include hinges, railing systems, and ground stakes.
Most common type. Good welding, forming, & strength. Low cost structural steel.
