Zinc plating is a subcategory of electroplating, which refers to the use of an electric current to dissolve a metal, in this case zinc, in a solution bath for the purpose of forming a metal coating on a part.
The solution in the baths may vary, but at Paulo this process is normally used for small parts rather than sheets of metal. These could include screws, fasteners, nut, bolts or other small hardware pieces. Zinc plating may be conducted to enhance a product’s corrosion control characteristics, or as an aesthetic finish for small parts that may be visible on a fully assembled product.
Since zinc plating is traditionally performed on large batches of small parts, manufacturers looking to contract out this important service will want to make sure they’re working with a partner that has the capacity to handle large volumes of parts.
