What is the Difference Between Chrome Plating, Nickel Plating and Zinc Plating in Steel Structures?

Jun. 29, 2020

Avoid using galvanized sheets, nickel-plated sheets, etc. in the steel structure! Today China Modern Steel Structure Manufacturers try to explain what electroplating! How about galvanized sheet!

First, let's understand what electroplating is:

Electroplating is the process of plating a thin layer of other metals or alloys on the surface of certain metals using the principle of electrolysis. It is a process of using electrolysis to attach a metal film to the surface of metal or other materials to prevent metal oxidation. Improve wear resistance, electrical conductivity, reflective properties, corrosion resistance and enhance aesthetics.

Electroplating is divided into copper plating, gold plating, silver plating, chromium plating, nickel plating and zinc plating and other specific processes. In the field of industrial design, it is most widely used in zinc plating, nickel plating and chromium plating.

Let's take a look at the difference between the three.

1. Galvanized steel structure

Definition: Zinc plating refers to the surface treatment technology of plating a layer of zinc on the surface of metals, alloys or other materials for aesthetic and rust prevention.

Features: low cost, general anti-corrosion, silver-white color.

Application: all kinds of steel structures, screws, circuit breakers, industrial supplies, etc.

Appearance: galvanized appearance silver white.

The most basic difference: galvanizing is mainly beautiful and anti-rust. Zn is a reactive metal that can react with acids, so it has poor corrosion resistance and is the cheapest of the three.

2. Nickel plating in steel structure

Definition: The method of plating a layer of nickel on a metal or some non-metals by electrolytic or chemical methods is called nickel plating.

Features: beautiful, can be decorated, the price is high, the process is slightly complicated, the color is silver and yellow.

Applications: Energy-saving lamp holders, coins, etc.

Appearance: Nickel-plated appearance silvery white yellowish.

The most basic difference: Nickel plating is mainly wear-resistant, anti-corrosion, anti-rust, generally thin, the process is divided into electroplating and chemical.

3. Chrome plating in steel structure

Definition: Chromium is a slightly bluish silver-white metal. The method of plating a layer of chromium on metals or certain non-metals by electrolytic or chemical methods is called chromium plating.

Features: There are two kinds of chrome plating, the first one is for decoration, bright appearance, good abrasion resistance, rust resistance is not as good as galvanized, better than oxidation; the second is to increase the hardness and wear resistance of metal parts, etc. , This is the functionality of the part.

Application: Bright decorative parts on household appliances, electronics and other products, faucets, etc.

Appearance: Chrome plating is divided into decorative chromium and hard chromium.
