GP Coil is a type of steel coil that is coated with a layer of zinc to protect it from corrosion. The galvanizing process involves immersing the steel coil in a bath of molten zinc, which reacts with the steel to form a layer of zinc coating. GP Coils are commonly used in various applications, including automotive, construction, and appliances. The primary advantage of the GP Coil is its superior resistance to corrosion.
