Conventional electrolytic nickel plating from a Zhongshan plating factory
Guoshuo provides conventional electrolytic nickel plating. Nickel deposits are hard-wearing, corrosion resistant, and bond tightly to the base metal, which makes nickel one of the most widely specified finishes for hardware, appliance components, and automotive parts. It works as a protective finish in its own right and as the undercoat beneath decorative chrome.
Backed by 33 years of plating experience and multiple automated plating lines, we run nickel plating at volume with stable, repeatable results. Salt spray and coating-thickness testing are available on request.

Quality & Testing
Salt spray testing and coating-thickness measurement can be arranged to agreed specifications. Existing food-contact reports apply only within the product and process scope stated in each report; they do not establish compliance for a different substrate, coating stack, production process or intended use. For other products, project-specific third-party testing and reports can be arranged according to customer and target-market requirements. RoHS and other material requirements are likewise confirmed against the applicable product and report scope.
Frequently Asked Questions
What is the difference between nickel and chrome plating?
Nickel gives a softer, silver-white finish and carries most of the corrosion protection. Chrome is harder, brighter, and more wear resistant, but the decorative chrome layer is thin and porous. In practice, decorative parts are nickel plated first and chrome plated on top, so you get both properties.
What coating thickness can you achieve?
Thickness is specified to the application and to your drawing. We confirm the exact range during sampling, and we can verify it by X-ray or cross-section measurement.
Can nickel plated parts pass a salt spray test?
Yes. Salt spray testing can be arranged on request, and our parts meet a 72-hour neutral salt spray (NSS) standard.
