Anti-Corrosion Technology of Zinc Steel Fence
Our core anti-corrosion technology goes beyond surface treatment. Our promise of a 15+ year service life is built on a rigorous, multi-layer protective process.
- High-Zinc Content Steel Base
We start with premium steel plates containing ≥60% zinc content . This provides robust “sacrificial” protectionat the material’s core. Even if the surface coating is damaged, the zinc layer continuously inhibits rust formation. - Nano-Phosphating Enhancement Layer
Prior to coating, the base material undergoes a phosphating treatment , creating a micro-crystalline protective layer. This significantly enhances coating adhesion , effectively preventing peeling or flaking . - High-Strength Electrostatic Spray Coating
We use top-grade polyester resin powderfrom internationally renowned brands. The resulting coating offers exceptional UV stability , corrosion resistance , and a wide selection of colors. - High-Temperature Curing
Curing at 220°C (220°C) fuses the coating and base material into one. Achieving a hardness of over 2H, the finish is highly wear and scratch-resistant , maintaining its integrity over time.Performance Verified for Your EnvironmentExceptional Weather Resistance: Tested to withstand ≥1000 hours of neutral salt spray , far exceeding local standards. It performs perfectly in environments ranging from Hanoi’s humidity to Da Nang’s coastal salt spray。
Long-Lasting Appearance: We guarantee no significant coating fade within 10 years, drastically reducing long-term maintenance costs.
- Robust & Durable: With an overall designed service life exceeding 15 years, it provides reliable protection for your residential communities, industrial parks, roads , or coastal projects
