Galvannealed coils are the result of combining hot dip galvanizing and annealing in one line. After galvanizing the product is being annealed to give its typical characteristics. Galvannealed coils do not give off their coating when formed, stamped, and bent. They have a grey finish which acts as a primer allowing paint to adhere easily. Galvannealed coils are very rust proof and offer good weldability.
