Zinc Plating

Keep rust and corrosion away.

Your steel and iron parts need to last, even in mildly corrosive environments. Zinc plating prevents rust, corrosion, and moisture damage with a bright, attractive, durable coating trusted by the automotive industry for over 100 years.

Pitfalls of Corrosion

Steel and iron surfaces rust easily, even in mildly corrosive environments. Rust leaves ugly surface stains on parts and components. It also weakens structures and reduces mechanical performance. In addition to protecting against rust, zinc can be cast into a wide range of precision parts for automobiles, airplanes, appliance manufacturing, construction materials, and electronics.

Durable Parts Increase Customer Satisfaction

Ensure your parts live up to customer standards, and apply zinc plating for:

  • Rust protection
  • Long-lasting finish
  • Bright jewel-like appearance
  • Increased solderability
  • A lower corrosion rate than steel (in most atmospheres, when in contact with water)

Choose from the Full Range of Trivalent Passivation Options

Trivalent passitives are the first line of defense against corrosive attacks on plated coatings. The thin, protective film on chromate finishes makes coatings more durable and increases the overall value of metal coatings. KC Jones provides the full range of chromate conversion coatings.

KC Jones Offers Acid & Alkaline Zinc Processes

Alkaline Zinc

  • Ductile coating, with excellent post plate forming capability
