Most fencing and gate manufacturers face a critical challenge when trying to scale up their surface finishing process: how to achieve a strong, weather-resistant, and attractive coating while controlling production cost. Powder coating has become the preferred solution for this industry—but setting up the right powder coating line is key.
Yantai Clear brings you practical guidance on how to build a high-performance powder coating line tailored for fencing and gate production.
Why Powder Coating Is Ideal for Fences and Gates
Metal fences and gates are constantly exposed to outdoor environments—UV rays, rain, humidity, corrosion, and even physical impact. Powder coating creates a hard, durable, and beautiful finish that can last for over 10 years without fading or rusting.
Compared with traditional wet painting, powder coating offers:
Better corrosion resistance
Uniform film thickness and coverage
No dripping or sagging
Environmentally friendly process with no solvents
That’s why top fencing manufacturers are shifting to full or semi-automatic powder coating lines.
Key Components of a Powder Coating Line for Fencing
Metal fences and gates come in different shapes, materials, and sizes. Whether you’re coating flat panels, decorative iron gates, or galvanized steel mesh, your powder coating line must be flexible yet efficient.
A typical powder coating line includes:
Pre-treatment Tunnel or Spray Booth
To remove oil, rust, or zinc ash from galvanized surfaces.
Multi-stage options (degreasing → rinsing → phosphating → drying) for strong adhesion.
Drying Oven
Evaporates all moisture before powder application.
Automatic or Manual Powder Spray Booth
Manual booth preferred for complex or limited batches.
Automatic reciprocators recommended for large batch runs.
Powder Coating Curing Oven
Ensures powder flows, melts, and bonds to the surface at 180–200°C.
Tunnel-type ovens ideal for longer fencing products.
Overhead Conveyor System
Adjustable speed and load-bearing for fence frames or gate panels.
Powder Recovery System
Cyclone and filter units to save powder and reduce waste.
Common Sizes & Layout Recommendations
Workpiece Length: up to 3–6 meters
Weight Capacity: 50–200 kg per hanging frame
Line Type Options:
U-shape or L-shape for compact factory spaces
Linear flow line for higher daily output
Batch-type line for small workshops or customized orders
We always suggest customizing the line based on your product dimensions and daily production capacity.
What You Need to Consider Before Investing
Before you build your powder coating line for fencing and gates, think through:
How many square meters of product do you coat per day?
Are your fences made of black steel, aluminum, or galvanized metal?
Do you require color changes? If yes, how frequent?
What’s your available factory space?
Do you plan to expand capacity in the next 2–3 years?
