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.
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.
-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.
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)
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
✔ Lasts 2-3x longer than paint (fewer replacements needed)
✔ Scratch & chip-resistant (maintains appearance for years)
✔ Minimal upkeep (no frequent repainting)
✔ Zero VOC emissions (no toxic fumes)
✔ No hazardous solvents (safe for workers & the environment)
✔ Excess powder can be recycled (reduces waste)
Metal is cleaned & treated (removes oils, rust, and debris)
Ensures strong adhesion for the powder
Powder is sprayed with an electrostatic charge
Evenly sticks to the metal surface
Cabinet is baked at high temperatures (~200°C)
Powder melts into a smooth, hard finish
Coating is checked for thickness, adhesion, and defects
Ensures maximum protection before shipping
✔ Prevents signal interference (non-conductive coatings)
✔ Resists vandalism & graffiti (tough, smooth surface)
✔ Withstands decades of sun & rain exposure
✔ Protects against battery acid leaks
✔ Improves heat dissipation (some coatings aid cooling)
✔ Fire-retardant options available (safety for lithium-ion batteries)

Hinges and other key components of communication cabinets in coastal areas
RAL Color Matching for Corporate Identity,for example RAL7035 OR RAL9006
Texture Options (Matte/Glossy/Textured)
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)
Answer:Industry-Standard Lifespan:7-15 years for communication/energy storage cabinets/telecom enclosures
Answer:Yes, but with critical preparatory steps
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).
