Corrosion remains one of the most persistent and costly challenges in industrial and construction environments. Over time, exposure to moisture, chemicals, and oxygen can compromise the structural integrity of metallic components. The result? Increased maintenance costs, unscheduled downtime, and in some cases, serious safety risks.
To maintain long-term performance and operational reliability, it’s essential to address corrosion early — and effectively. That’s where Zinga comes in.
What is Zinga?
Zinga is an advanced cold galvanizing system that delivers the same cathodic protection offered by traditional hot-dip galvanizing — but with greater flexibility and convenience. It consists of high-purity zinc dust suspended in a binder that forms a protective, sacrificial zinc layer when applied to steel.
This means that even if the coating is scratched or damaged, the zinc continues to protect the underlying metal by corroding first — ensuring long-lasting durability and protection.
Where Zinga Works Best
Zinga is ideal for a wide range of industrial and structural applications, including:
- Structural steel frameworks
- Factory supports and platforms
- Storage tanks and silos
- Marine and coastal installations
- Bridges and towers
- Maintenance and repair of previously galvanized surfaces
Whether it’s a new installation or the refurbishment of corroded steel, Zinga offers a cost-effective, long-term protection solution.
Application and Solvent Use
One of Zinga’s biggest advantages is its ease of application. It can be applied using a brush, roller, or spray, depending on the nature of the surface and the project scale.

The solvent used is Zingasolv, a specially formulated thinner that ensures smooth application and proper film formation. Depending on the surface profile and film thickness, 1kg of Zinga covers approximately 1.5 to 2.5 square metres.
Surface Preparation: The Key to Performance
As with any coating, surface preparation is critical. Proper cleaning ensures maximum adhesion and longevity of the Zinga coating.
Recommended preparation steps include:
- Degreasing to remove oil, dirt, or contaminants.
- Abrasive cleaning or sandblasting (ideally to Sa 2½) to eliminate rust, scale, and old paint.
- Brushing or grinding in areas where blasting is not practical.
- Ensuring the surface is clean, dry, and free of dust before application.
Why Choose Zinga?
Zinga combines the benefits of galvanizing and paint systems in one solution. It:
- Provides true galvanic (cathodic) protection
- Can be applied on-site — no dismantling required
- Is ideal for touch-up and repair of existing galvanized structures
- Offers a long service life, reducing maintenance frequency
- Is environmentally friendly and can be recoated or overpainted if required
Final Thoughts
Corrosion control doesn’t have to mean costly replacements or disruptive repairs. With Zinga, industries can extend the lifespan of their steel assets while minimizing downtime and long-term costs. It’s a reliable, efficient, and proven solution for safeguarding metal structures — one layer at a time.
