Zinc Plating (Electrogalvanizing)
Electro-deposition process delivering essential sacrificial corrosion protection for precision fasteners and hardware.
Process Overview
Zinc plating is identical to electro-galvanizing in principle because both are electro-deposition processes. However, zinc plating is optimized for small parts such as fasteners, crank handles, springs, and other hardware items rather than continuous sheet metal.
Zinc plating is typically used for screws, small fasteners, light switch plates, and various small parts that will be exposed in interior or mildly corrosive conditions. For use in moderate or severe environments, the materials are chromate-conversion coated to impart substantial additional corrosion protection.
Applications & Suitable Objects
- Industrial screws, bolts, nuts & precision fasteners
- Mechanical springs, levers & crank handles
- Electrical light switch plates & stamped brackets
- Automotive under-hood hardware components
Finishing Characteristics & Benefits
Sacrificial Galvanic Defense
Zinc corrodes preferentially to shield the underlying ferrous steel.
Precision Dimensional Tolerances
Micro-thin uniform deposit prevents thread interference.
Chromate Conversion Coating
Passivation options significantly enhance salt spray resistance.
Cost-Effective Industrial Protection
Economical high-volume coating for critical hardware.
