Zinc Plating
Zinc plating is an electrolytic treatment used to protect metals from corrosion. This process is essential to ensure the durability and resistance of materials, especially in environments exposed to moisture and atmospheric agents.
Thanks to its anodic properties, zinc provides galvanic protection even on exposed areas due to porosity, imperfections, and surface damage. This happens because the corrosion products generated by zinc help preserve it from new corrosive attacks.
Technical Characteristics
An alkaline bath without cyanide is used with high thickness uniformity. The surface appearance after treatment can be semi-glossy or glossy depending on the base material, while the color varies according to the passivation requested by the client.
The available passivations are:
- White
- Black
- Iridescent High Resistance
Materials Treated
- Aluminum
- Copper
- Brass
- Iron
Allowed Dimensions
Frame processing up to 4 meters in length.
Types of Treatment
- Frame
Frequently Asked Questions
5Electrolytic zinc plating is a treatment that deposits a zinc layer on metal surfaces to protect them from corrosion. Thanks to its anodic properties, zinc provides active galvanic protection: even in the presence of scratches or imperfections, the zinc sacrifices itself to protect the underlying base metal.
White passivation offers a light appearance and is suitable for aesthetic applications and indoor environments. Black passivation provides a dark decorative finish. High-resistance iridescent passivation offers maximum corrosion protection and is recommended for components exposed to aggressive or outdoor environments.
Yes, electrolytic zinc plating is particularly suitable for components exposed to humidity and atmospheric agents. High-resistance iridescent passivation offers the best protection for aggressive environments. To determine the most suitable treatment for your specific needs, we recommend contacting us for a technical consultation.
Yes, the process uses a cyanide-free alkaline bath with high thickness uniformity, ensuring even coverage on parts with complex geometries. Supergalvanica can process components on frames up to 4 metres in length.
Zinc plating adds a thin layer to the component surface. Thickness is precisely controlled according to specific client requirements and applicable standards. For applications with tight tolerances, we recommend consulting our technicians to determine the optimal thickness.
