What Are ZENOME's Anti-Corrosion Standards for Street Light Poles?
What Are ZENOME's Anti-Corrosion Standards for Street Light Poles?
ZENOME street light poles utilize a dual-layer anti-corrosion system (Hot-Dip Galvanizing + Electrostatic Powder Coating) , designed to ensure a 20 to 30-year service life even in extreme environments such as coastal areas, deserts, and industrial zones.
Below are the specific anti-corrosion technical standards:
1. Hot-Dip Galvanizing Standard
This is the most core anti-corrosion process for street light poles, covering both the inner and outer walls of the pole body.
|
Parameter |
Specification |
|
Compliant Standards |
Strictly complies with GB/T 13912-92, ISO 1461, and ASTM A123 (for North America and specific projects). |
|
Zinc Layer Thickness |
– Standard poles (6-12m): ≥ 85 μm |
|
Quality Performance |
Smooth surface with consistent color. Passes the maul test (hammer test), verifying that the galvanized layer does not peel or flake. |
2. Electrostatic Powder Coating Standard
This secondary protection layer is applied over the galvanized layer, primarily to enhance aesthetics and UV resistance.
|
Parameter |
Specification |
|
Material |
Pure polyester powder, offering strong adhesion and excellent resistance to UV degradation. |
|
Coating Thickness |
Powder coating film thickness ≥ 100 μm. |
|
Adhesion Test |
Passes the cross-cut test (scribing a 15mm × 6mm grid on the surface), ensuring the coating does not peel or flake off. |
|
Color Durability |
Supports RAL or Pantone color customization, with color retention lasting up to 15 years. |
3. Enhanced Standards for Special Environments
|
Environment |
Enhanced Protection |
|
Coastal & High Salt-Spray Areas |
An additional epoxy primer coating can be applied, combined with specialized protection (thickness < 1.0 mm) to resist salt-spray corrosion. |
|
Underground / Buried Sections |
For the buried portion, bituminous painting is typically applied to the bottom 1.5 meters for extra protection. |
|
Fasteners |
All bolts, nuts, and anchor bolts are made of stainless steel to prevent rust and ensure long-term structural stability. |
4. Performance Certifications & Warranty Commitment
