1. The appearance and color are different

The surface of galvanized parts is a little bluish white, shiny but not very shiny. After passivation treatment, it can be made into blue white zinc, colorful zinc, black zinc, army green and other colors.

The chrome-plated surface is bright white and bluish, and the other chrome-plated colors are black chrome.

2. The functions of chrome plating and zinc chrome plating are different

Galvanizing is just to coat a layer of zinc metal of several micrometers to ten micrometers on the surface of the electroplated parts. It is an anodic coating for the iron base, which has a certain degree of electrochemical protection, and the galvanized parts have good rust resistance.

Chrome plating is divided into decorative chrome plating and hard chrome plating. Chrome plating is to electroplate a single chrome metal layer of several microns or more than ten microns on the surface of electroplated parts. It has excellent wear resistance. Decorative chrome must be plated on the product first. After copper or nickel plating, there is a very thin chromium layer of chromium, which has beautiful and protective functions. It is mainly used for processing and using products with higher decorative requirements.


3. The cost of chrome plating and galvanizing is different

The cost price of galvanizing is low, while the cost of chromium plating is relatively high. In terms of the materials used in the electroplating process, the labor used in the electroplating process, and the maintenance of the electroplating process, the cost of chrome plating is higher than that of galvanizing.
