Galvannealed Steel Sheet

Galvannealed Steel Sheet

We are ranked amongst the key Manufacturers, Suppliers and Exporters of Galvannealed Steel Sheet. Our Galvannealed Steel Sheet are fabricated using supreme quality steel, to ensure their sturdiness and high durability.

Moreover, our Galvannealed is a form of hot-dipped galvanized sheet consisting of an iron-zinc alloy coating on both sides. It is produced from Cold Rolled coil (or Hot Rolled Pickled & Oiled typically thicker than 14-gauge) that has been passed continuously through a pot of molten zinc. The coating amount applied to the surface is controlled by wiping, rollers and/or air jets. When the coil exits the zinc bath, the molten zinc is subjected to inline annealing (thus the name �Galvannealed�) that forms the zinc-iron alloy layer. It is subsequently run through leveling rolls for shape correction. The coating is denoted by an �A� designation, i.e., A60 (as opposed to regular Galvanized denoted with a �G� prefix, i.e., G60). Galvannealed has a uniform light-medium gray color and a semi-porous finish. Galvannealed is especially intended for painting applications. Compared to regular hotdipped Galvanized, it has better corrosion resistance and a harder coating that is more resistant to scratching.

Generally, Galvannealed has become the preferred product of automobile, appliance and many other OEMs and fabricators, given the product�s excellent paintability, and lower cost compared to Electrogalvanized. Since the 1980s, it has almost completely supplanted Bonderized (phosphatized). Galvannealed (like hot-dipped Galvanized sheet) is typically produced in accordance with ASTM A653 standards and tolerances.
