Galvannealed or galvanneal is the result from the combined process of galvanizing and annealing to produce specialized sheets of steel. The galvanization is made through the hot-dipping (Hot-dip galvanizing) process and an immediate in-line annealing and gives a very fine greyish matte finish. Galvanneal does not flake off its galvanized coating when formed, stamped, and bent. The very fine matte finish acts like a primer, allowing paint to adhere easily, and is very rust proof; only white to dark grey marks appear if it comes in contact with water. Galvanneal sheets offer good paintability, weldability, corrosion resistance, and formability. It is extensively used in the automotive, signage, electric equipment, and other industries requiring a metal with good paintability and long reliable service life. This steel process is produced by many steel mills and it is commonly referred by its trade name of Jet-Kote.
