Zinc Blue Plating Services in Nashik
Zinc blue plating is the workhorse finish for steel components: a bright electrodeposited zinc layer that corrodes sacrificially to protect the base metal, sealed with a blue passivation for a clean, uniform silver-blue appearance. At KVEE METALS we process zinc blue in barrel and rack lines for high-volume automotive fasteners and engineering hardware, with every lot tracked against your delivery challan.
Why choose this finish
Benefits of Zinc Blue Plating
Sacrificial corrosion protection
Zinc corrodes in preference to steel, protecting the part even at scratches and cut edges.
Uniform bright finish
Consistent silver-blue appearance across the batch for visible and assembly-line parts.
Barrel or rack processing
Small fasteners run in barrels; larger brackets and stampings are racked to protect geometry.
Cost-effective at volume
The most economical electroplated finish for large monthly volumes.

FAQ
Zinc Blue Plating questions
What is zinc blue plating used for?
Zinc blue plating gives steel parts sacrificial corrosion protection with a bright, uniform silver-blue finish. It is widely used on automotive fasteners, brackets, clamps and general hardware where cost-effective corrosion resistance and a clean appearance are needed.
How thick is the zinc layer?
Typical deposits are 5 to 12 microns. Thickness is set to your drawing or standard (for example ASTM B633 or ISO 2081 service condition classes) and can be increased for more demanding environments.
Do you plate small fasteners in bulk?
Yes. Small fasteners and hardware are processed in barrel lines, which is efficient for large volumes. Larger or delicate parts are racked to protect threads and geometry.
