Anti-Rust Barrier Gate: How ACCESS TECH’s Multi-Stage Coating System Ensures Maximum Durability

Since 1999, ACCESS TECH has specialized in manufacturing anti-rust barrier gate built to perform in the most demanding environments. Our multi-stage surface treatment process combines phosphating, electrophoretic coating, and electrostatic powder coating to deliver unmatched corrosion resistance, mechanical strength, and aesthetic longevity.

Stage 1: Phosphating – The Critical Foundation

The process begins with phosphating, a chemical surface treatment that serves two essential functions:

• Deep Cleaning: Removes all impurities, including oils, rust, mill scale, and other contaminants, from the metal cabinet surface.

• Surface Activation: Creates a microcrystalline phosphate layer that significantly enhances the adhesion of subsequent coatings and provides preliminary corrosion resistance.

Stage 2: Electrophoretic Coating – Total Coverage with Molecular Anchoring

Following phosphating, the cabinet undergoes electrophoretic coating (E-coating), which offers far more than just surface-level protection:

• Molecular Anchoring: The paint particles penetrate into microscopic pores on the metal surface during the electrochemical process, forming a powerful “anchor” effect that results in adhesion far superior to conventional spray painting.
• Exceptional Hardness: The cured e-coat layer is highly resistant to minor abrasion, impact, and handling scratches, maintaining integrity throughout the gate’s operational life.
• Uniform Protection: Ensures complete coverage—including edges, welds, and internal structures—leaving no room for corrosion to start.

Stage 3: Electrostatic Powder Coating + High-Temperature Curing – The Final Shield

After e-coating, a layer of resin-based powder is applied using electrostatic spraying. This stage offers several key advantages:

• Eco-Friendly & Efficient: The process is free of volatile organic compounds (VOCs), making it environmentally responsible.
• Excellent Adhesion & Uniform Color: Electrostatic attraction ensures the powder wraps the cabinet evenly, resulting in a consistent, high-quality finish available in custom colors.
• High-Temperature Curing: Once applied, the cabinet enters a high-temperature oven. The powder melts, flows, and chemically cross-links into a durable, smooth film. After cooling, the finish exhibits extreme adhesion and impact resistance—far outperforming conventional wet paints.

Why This Multi-Stage Coating System Is So Effective

Together, these stages form a synergistic defense:

• Phosphating cleans and prepares the surface.
• E-coating seals the metal with deep-binding, rust-inhibiting protection.
• Powder coating adds a tough, flexible, and colorful outer shell that withstands physical and environmental stress.
