Galvanizing
Galvanizing is a process in which a zinc coating is applied to the surface of steel or iron. This coating prevents corrosion and wear, and can also add to the aesthetic of the metal. Galvanizing is often used on steel components that will come into contact with moisture, such as nails and fasteners.
Anodizing
Anodizing is a process in which an oxide layer is applied to the surface of aluminum. This layer provides protection against corrosion and wear, and also increases the surface hardness of the metal. Anodizing can also improve the appearance of the metal, as it can be dyed in a variety of colors.
Electroplating
Electroplating is a process in which a metal coating is applied to the surface of a metal substrate. This coating can improve the appearance of the metal, as well as providing protection against corrosion and wear. Common metals used in electroplating include nickel, copper, and chromium.
