The main difference between ordinary zinc plating and yellow chromate zinc plating is the treatment method and corrosion resistance.
Treatment method
ordinary zinc plating : ordinary zinc plating is to achieve rust prevention and beautiful effect by covering the metal surface with a layer of zinc. The specific methods include hot dip plating and electroplating. Hot-dip plating involves dipping a metal work piece into a molten zinc solution, while electroplating involves depositing a layer of zinc on a metal surface by electrolysis.
yellow chromate zinc plating : yellow chromate zinc plating is on the basis of ordinary zinc plating, and then chromate treatment. This treatment will form a chromate film on the surface of the zinc coating, resulting in a yellow surface.
Corrosion resistance
ordinary zinc plating : ordinary zinc layer has good anti-corrosion performance, can protect the metal from the erosion of atmosphere, water and chemicals. The standard electrode potential of zinc is -0.76V. For steel matrix, zinc coating is anodic coating, which can effectively prevent steel corrosion.
yellow chromate zinc plating : The chromate treated zinc layer has stronger corrosion resistance. Bichromate treated zinc plating is resistant to salt spray for a longer time and therefore exhibits better corrosion resistance in harsh environments such as Marine climates.
Superior Corrosion Resistance:Zinc plating with yellow chromate enhances rust protection, ideal for humid or harsh industrial environments.
High Precision & Durability:Cold-rolled steel ensures dimensional accuracy, rigidity, and long-term wear resistance.
Low-Profile Aesthetic:Concealed design maintains a clean, professional appearance while providing critical alignment or labeling functionality.
Enhanced Conductivity:Zinc chromate coating offers mild electrical conductivity, suitable for grounding or static-sensitive applications.
Cost-Effective Longevity:Combines industrial-grade materials and surface treatments to minimize maintenance and replacement costs over time.
Aesthetics : After yellow chromate on zinc plating, the appearance of the stamped parts is more beautiful and smooth, and it has properties such as oxidation resistance and wear resistance, which can improve the quality and quality of the product .
Environmental protection: the materials and liquids used in the zinc plating process are environmentally friendly materials, will not cause pollution and harm to the environment, in line with the national environmental protection requirements .
Industrial Machinery:Ideal for precision alignment markers in CNC machines, robotic arms, or assembly lines exposed to oils, coolants, or moisture.
Automotive Manufacturing:Used in engine components, sensor mounts, or chassis systems requiring corrosion resistance and electrical grounding.
Electronics & PCB Assembly:Provides durable labeling or alignment guides in static-sensitive environments, leveraging mild conductivity for safe handling.
Aerospace & Defense:Critical for equipment calibration plates or instrumentation panels in high-humidity or chemically aggressive settings.
Medical Equipment:Ensures long-lasting, contamination-resistant indexing in sterilized devices or diagnostic machinery.
1Q: How does the yellow chromate on zinc plating benefit the product?
1A: The zinc plating with yellow chromate provides robust corrosion resistance, enhances surface durability, and prevents oxidation in humid or chemically harsh environments.
2Q: Is this plate pre-drilled for easy installation?
2A: Yes, it features pre-fabricated mounting points for seamless integration into machinery, electronics, or automotive systems without additional modifications.
3Q: Are custom sizes or markings available?
3A: Standard sizing suits most applications, but custom dimensions or laser-etched markings can be requested for specialized alignment or labeling needs.
4Q: Can it withstand high-moisture or corrosive settings?
4A: Absolutely—the zinc-chromate coating protects against rust, chemicals, and humidity, ensuring reliability in demanding conditions like marine or industrial facilities.
5Q: Do you have any quality certificate ?
5A: We are ISO 9001 certified.
