Standard Coating Booth Overview

• Modular, Easy-to-Assemble Design – Simplifies installation and maintenance.

• Cleanable Interior & Exterior – Smooth surfaces allow for quick and efficient cleaning.

• Automatic Spraying System – Two sets of automatic spray guns positioned on each side.

• Manual Spraying Support – Two manual spray gun groups per side for touch-up or precision work.

• Air Supply Connections – Compressed air fittings provided on both sides of the booth.

• Powder Containment Shields – Protective barriers at the entry and exit minimize powder escape.

• Optimized Lighting – Six explosion-proof “three-protection” lighting fixtures installed on the ceiling; illumination ≥300 lux.

• Emergency Stop Control – A main emergency stop button located at the operator’s control point allows for immediate conveyor shutdown in urgent situations.

• Optional Custom Designs – Nonstandard booths available upon request.

• Exterior Construction Flexibility – The outer enclosure may be built by the end user based on site conditions.

Coating Booth Material Options

The performance and durability of a coating booth depend greatly on the construction material. Each material—PVC, PP, carbon steel, and stainless steel—offers unique advantages suited for different coating environments.

1. Polyvinyl Chloride (PVC) Booths

Pros:

• Economical and budget-friendly

• Self-extinguishing for improved fire safety

• Resistant to many common coating chemicals

Cons:

• Temperature limit below ~60°C

• Moderate chemical resistance range

• Lower impact strength than metal booths

Best for: Cost-sensitive operations with light-to-moderate chemical exposure

2. Carbon Steel Booths

Pros:

• Excellent structural strength for industrial loads

• 30–50% lower cost than stainless steel

• Compatible with a broad range of coating materials

Maintenance:

• Regular repainting or corrosion protection required

• Humidity control recommended

Applications: Automotive, machinery, general manufacturing, heavy equipment

3. Stainless Steel Booths

Advantages:

• High corrosion resistance due to chromium content

• Heat-resistant above 200°C

• Hygienic, smooth surface compliant with sanitary standards

Considerations:

• Higher initial cost (2–3 times that of carbon steel)

• Longer return-on-investment cycle

Ideal for: Food and pharmaceutical equipment, marine use, premium automotive finishes

4. Polypropylene (PP) Booths

Benefits:

• Outstanding chemical resistance to acids and solvents

• Non-corrosive—ideal for high-humidity conditions

• Lightweight structure for easy installation and relocation

Limitations:

• Maximum operating temperature around 90°C

• Less impact resistance compared to metals

Best suited for: Electronics, chemical processing, and specialty coatings

Choosing the Right Material

Selecting the right coating booth material depends on several factors: coating type, environmental exposure, chemical compatibility, operating temperature, cost considerations, and applicable safety or environmental regulations. Consulting with specialists ensures that your coating booth achieves the best balance of performance, durability, and value.
