Hot dip galvanized (GI) steel is a two-side, zinc-coated product produced through a continuous process comprised of cleaning, annealing and coating. GI steels are available in a wide range of qualities, including specifications with good forming characteristics and high strengths, and with a variety of coating weights. Spangle is minimized through alloy additions in the zinc bath, thus providing a uniform looking surface. Temper rolling further improves the surface along with locking in mechanical properties and desired surface roughness. The zinc surface is temporarily protected from oxidation or white rust by applying an oil or chemical treatment. GI product has a somewhat shiny "zinc color" appearance.
Galvanized products provide overall corrosion resistance and superior non-flaking properties. The tightly adhering zinc coating will take the most severe forming operations without flaking or peeling, thereby reducing maintenance and die wear. It is readily welded using conventional techniques. Uniform coating weight control and distribution also allows for good spot weldability. It is among the most cost effective, corrosion resistant steel sheet products on the market today.
