What Is Powder Coating RAL7035 In Telecommunication Enclosure Field?


What is Powder Coating?

Powder coating is an advanced dry-finishing process that applies a protective layer to metal surfaces. Unlike traditional liquid paint, it uses an electrostatically charged powder that bonds to the metal and is then heat-cured for maximum durability.

What is RAL7035?


RAL 7035 (Light Grey)is a color code from the RAL Classic color system, which is widely used in Europe for industrial and architectural applications.


Common Uses:

-Industrial coatings

-Machinery and equipment

-Architectural facades

-Military and aviation applications (often as a camouflage or neutral base color)


But what does powder coating do exactly? For outdoor communication cabinets and battery enclosures, it provides critical protection against weather, corrosion, and wear—ensuring long-lasting performance in harsh environments.

What Does Powder Coating Do For Telecom Enclosures? Key Benefits Explained


1. Creates a Durable, Weatherproof Shield


Powder coating forms a thick, uniform layer that protects against:

✔ UV rays (prevents fading & material breakdown)

✔ Rain, snow, and humidity (no peeling or rust)

✔ Extreme heat & cold (withstands -30°C to +70°C)


2. Prevents Corrosion & Chemical Damage


telecom enclosures face rust, salt spray, and chemical exposure. Powder coating:

✔ Blocks moisture & oxygen (stops rust before it starts)

✔ Resists battery acids & industrial pollutants (ideal for energy storage)

✔ Performs well in coastal & high-pollution areas


3. Enhances Longevity & Reduces Maintenance


✔ Lasts 2-3x longer than paint (fewer replacements needed)

✔ Scratch & chip-resistant (maintains appearance for years)

✔ Minimal upkeep (no frequent repainting)


4. Offers Eco-Friendly & Safe Protection


✔ Zero VOC emissions (no toxic fumes)

✔ No hazardous solvents (safe for workers & the environment)

✔ Excess powder can be recycled (reduces waste)




How Powder Coating Works for telecom enclosures?


Step 1: Surface Preparation


Metal is cleaned & treated (removes oils, rust, and debris)

Ensures strong adhesion for the powder


Step 2: Electrostatic Application


Powder is sprayed with an electrostatic charge

Evenly sticks to the metal surface


Step 3: Heat Curing


Cabinet is baked at high temperatures (~200°C)

Powder melts into a smooth, hard finish


Step 4: Final Inspection


Coating is checked for thickness, adhesion, and defects

Ensures maximum protection before shipping




Why Outdoor Communication & Battery Cabinets Need Powder Coating?


  • For Communication Cabinets (5G, Telecom, Fiber Optic)


✔ Prevents signal interference (non-conductive coatings)

✔ Resists vandalism & graffiti (tough, smooth surface)

✔ Withstands decades of sun & rain exposure


  • For Battery Enclosures (Energy Storage, EV, Solar)


✔ Protects against battery acid leaks

✔ Improves heat dissipation (some coatings aid cooling)

✔ Fire-retardant options available (safety for lithium-ion batteries)



Technical Selection Guide


Choosing the Right Powder Coating Type

  • Polyester vs Epoxy-Polyester Hybrids

1.Polyester Powder Coatings

Best for: UV resistance & outdoor durability

Key Attributes:

✓ Superior Weather Resistance

2000+ hours QUV accelerated weathering test

Less than 5% chalking after 5 years (Florida exposure test)

✓ Color Retention

ΔE<2 after 3000 hours xenon arc testing

Preferred for RAL 7035/9005 Standard colors for the telecommunications industry


2.Epoxy-Polyester Hybrids


Best for: Chemical resistance & mechanical strength

Key Advantages:

✓ Enhanced Corrosion Protection

1500+ hours salt spray (ASTM B117)

Excellent acid rain resistance (simulated pH 2.5 environment test)

✓ Mechanical Performance

Impact resistance increased by 20% (ASTM D2794 160 in-lb

Edge coverage outperforms pure polyester (minimum 20μm at sharp edges)

Common Uses:

  • Battery cabinet internal frame

H6 Example : CATL energy storage cabinet internal bracket coating solution)

  • Hinges and other key components of communication cabinets in coastal areas


Color & Finish Considerations


  • RAL Color Matching for Corporate Identity,for example RAL7035 OR RAL9006

  • Texture Options (Matte/Glossy/Textured)



Conclusion: Is Powder Coating Worth It for telecom enclosures? -Absolutely!


Powder coating does more than just paint—it provides:

✅ Superior weather resistance

✅ Long-term corrosion protection

✅ Lower lifetime costs (less maintenance & replacements)

✅ Aesthetic flexibility (colors, textures, finishes)




FAQs About Powder Coated telecom enclosures


Ask:How long does powder coating last on outdoor telecom cabinets?

Answer:Industry-Standard Lifespan:7-15 years for communication/energy storage cabinets/telecom enclosures


Ask:Can powder coating be applied to existing cabinets?

Answer:Yes, but with critical preparatory steps


Ask:What warranties are typical for industrial powder coating?

Answer:Typical industrial powder coating warranties range from 5-15 years, depending on the coating type,substrate preparation quality, and environmental exposure (ISO 12944 C1-C5 classifications).
