Electrolytic and electroless nickel plating from a Zhongshan plating factory
Guoshuo provides electrolytic and electroless 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 more than twenty years of team 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.
Process Highlights
- Corrosion and wear resistant, protective and decorative
- Strong adhesion with a uniform, dense deposit

- Meets a 72-hour neutral salt spray standard
Materials & Applications
Base materials: Carbon steel, copper and copper alloys, zinc alloy (Zamak), stainless steel
Typical applications: Appliance components, automotive parts, bath hardware, lighting fittings, wire products, casters
Process Flow
- Incoming inspection and requirement review
- Pretreatment: degreasing, pickling, activation
- Electrolytic or electroless nickel plating

Quality & Certification
Salt spray testing (up to 72 hours) and coating-thickness measurement can be arranged on request. We can plate to US FDA and German LFGB food-contact standards and meet RoHS hazardous-substance requirements. Exact process parameters, such as thickness range and salt spray duration, are confirmed at the quotation and sampling stage.
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.
