The Ultimate Guide to Street Light Pole Specifications: From Q235 Steel to ISO 1461 Galvanization
The Ultimate Guide to Street Light Pole Specifications: From Q235 Steel to ISO 1461 Galvanization
In modern urban infrastructure, a street light pole is more than just a support for a luminaire; it is a critical structural component that ensures road safety and long-term durability. As a leading manufacturer, Zenome (Yangzhou Zenome Electric Co., Ltd.) is committed to providing high-quality pole solutions through precise material selection and rigorous industrial standards.
This guide provides a technical breakdown of the specifications that define a premium street light pole.
1. Core Material: Why Q235 Steel?
Street light poles are constantly exposed to environmental stressors and wind loads. Zenome utilizes Q235 Carbon Structural Steel as the primary material for several key reasons:
Balance of Strength and Ductility: Q235 offers an ideal carbon content, providing excellent tensile strength while remaining highly weldable and suitable for cold-bending into conical, octagonal, or polygonal shapes.
Load-Bearing Capacity: For a 10-meter pole with a 3.5mm wall thickness, the structural weight is approximately 171kg. This ensures the pole remains stable under high wind pressure, safeguarding traffic and pedestrians.
Stainless Steel Hardware: To prevent localized rusting at connection points, all bolts and nuts used in Zenome poles are made of stainless steel, ensuring the structure remains easy to maintain after decades of service.
2. Hot-Dip Galvanization: The ISO 1461 Shield
Corrosion is the greatest threat to steel structures, particularly in coastal or high-humidity regions. Zenome strictly adheres to the ISO 1461 (and GB/T 13912-2002) standards for hot-dip galvanization.
Pre-Treatment: Before galvanizing, the internal and external surfaces of the pole undergo rigorous acid pickling to remove all mill scale and oxidation.
Zinc Coating Thickness: We guarantee a zinc coating thickness of ≥ 85 μm. This coating forms a metallurgical bond with the steel, providing a sacrificial barrier that offers a service life of 20 to 30 years even in harsh environments.
Quality Assurance: The finished surface is smooth and uniform in color, and is tested via the "Mule Test" to ensure there is no flaking or peeling of the zinc layer.
3. Surface Treatment: Pure Polyester Powder Coating
For enhanced aesthetics and a secondary layer of environmental protection, Zenome applies an advanced electrostatic powder coating.
UV Resistance: We use high-grade pure polyester powder, which features exceptional resistance to ultraviolet (UV) rays, preventing fading or chalking after years of sun exposure.
Coating Specs: The film thickness exceeds 80 μm, providing a robust outer shell.
Adhesion Performance: Our coating undergoes a 15mm × 6mm square grid scratch test. The high adhesion strength ensures the finish will not peel or crack, even if the pole sustains minor physical impact.
Customization: We support the full spectrum of RAL and Pantone color systems, allowing poles to blend seamlessly into urban landscapes or corporate identities.
4. Structural Design & Safety Parameters
Zenome offers standardized configurations ranging from 6m to 12m to suit various road requirements:
6m Pole: Top diameter 75mm, base diameter 152mm, wall thickness 2.75mm. Ideal for residential streets and pathways.
10m Pole: Top diameter 75mm, base diameter 190mm, wall thickness 3.5mm. Designed for main highways and industrial zones.
Welding Quality: We utilize automatic submerged arc welding to ensure seams are level and smooth, free from cracks, undercut, or porosity, maintaining the mechanical integrity of the entire shaft.
5. Logistics and Global Reach
Understanding the importance of shipping efficiency, Zenome has optimized pole designs for international transport. For instance, a 40HQ container can accommodate approximately 160 sets of 6m poles or 120 sets of 10m poles, significantly reducing the landed cost per unit for our global partners.
Conclusion
From the structural stability of Q235 steel to the extreme corrosion resistance of ISO 1461 galvanization, every Zenome pole is engineered to withstand the test of time. We don't just provide lighting supports; we build the durable, safe, and aesthetic backbone of modern cities.
