Hot-dip galvanized pipe is the best choice for most processing techniques. Welding, torching, or abrasive sawing of galvanized steel is not recommended without proper protection and adequate ventilation. Galvanized pipe is A36 hot rolled steel or mild steel pipe that has been dipped in a molten zinc coating process (ASTM A123). Hot-dip galvanizing (HDG) can be identified by its crystalline pattern, also known as the “spangle” of the surface of the material. Excellent corrosion resistance, ideal for outdoor use or exposed environments. Common applications include potable water and drainage, fencing, posts, railing systems, and low-pressure piping.
