Explore engineered solar street lighting poles, split & all-in-one solar structures, decorative municipal posts, and high-mast steel towers compliant with international standards.
The Evolution of Solar Lighting Pole Infrastructure
Transitioning from conventional steel poles to structural solar-integrated light poles requires an elevated approach to structural dynamics, material science, and renewable energy conversion.
Grid Parity & Off-Grid Independence
Global infrastructure spending is rapidly pivoting toward decentralized renewable lighting networks. Municipalities and industrial parks deploy solar lighting poles to eliminate trenching costs, transformer upgrades, and copper wiring theft. Modern high-efficiency monocrystalline solar panels combined with LiFePO4 energy storage guarantee continuous illumination even through extended weather disturbances.
Structural Wind Drag Engineering
Unlike standard street light poles that only support small LED luminaires, solar light poles carry heavy photovoltaic modules at elevated mounting positions. This dramatically increases the Effective Projected Area (EPA) and wind drag coefficient ($C_d$). Precision engineering of pole wall thickness, taper ratios, and foundation anchor bolt layouts is paramount to withstand typhoon-grade wind speeds up to 260 km/h.
Smart City & IoT Integration
Solar lighting poles have evolved into multifunctional utility hubs. Contemporary urban tenders demand integrated smart poles equipped with 5G micro-base stations, CCTV surveillance, environmental sensors, EV chargers, and IoT smart gateways. Owning robust steel structural capabilities allows manufacturers to customize internal cable routing, hatch doors, and flange plates seamlessly.
Structural Metallurgy, Steel Grades & Hot-Dip Galvanizing
To achieve a 25-year structural service life under extreme environmental stressors, manufacturing solar lighting poles requires strict adherence to international metallurgical and hot-dip coating specifications.
Steel Selection: Q235B vs. Q355B Structural Steel
The foundation of structural integrity begins with certified steel coils sourced from top-tier steel mills (e.g., Baosteel, Shougang Group). We engineer solar lighting poles using premium Q235B or high-tensile Q355B structural steel (equivalent to ASTM A36 and ASTM A572 Grade 50 / EN 10025 S355JR).
- Q235B Steel: Ideal for standard municipal poles (3m to 10m height) with moderate wind loads. Excellent weldability and formability. Yield strength $\ge 235 \text{ MPa}$.
- Q355B Steel: Mandatory for heavy-duty solar poles (8m to 15m), high-mast towers (15m to 40m), and coastal regions subjected to high dynamic wind loads. Yield strength $\ge 355 \text{ MPa}$, providing a 51% increase in structural yield capacity.
Hot-Dip Galvanizing (HDG) per ASTM A123 / ISO 1461
Corrosion protection is non-negotiable for solar lighting poles exposed to outdoor humidity, marine salt spray, and atmospheric pollution. Every fabricated steel shaft undergoes chemical pickling, degreasing, fluxing, and full immersion in a molten zinc kettle ($450^\circ\text{C}$).
- Internal & External Protection: Zinc coating forms metallurgical zinc-iron alloy layers on both inside and outside pole surfaces.
- Minimum Coating Thickness: Guaranteed zinc layer thickness of $86 \mu\text{m}$ to $110 \mu\text{m}$ ($610 \text{ g/m}^2$), extending maintenance-free operation beyond 25 years.
- Optional Powder Coating: Architectural-grade electrostatic polyester powder coating (80-120 $\mu\text{m}$) baked at $200^\circ\text{C}$ in custom RAL colors for superior UV resistance and aesthetic integration.
| Pole Height (m) | Recommended Steel Grade | Top / Bottom Dia. (mm) | Wall Thickness (mm) | HDG Coating Depth ($\mu\text{m}$) | Max Design Wind Load |
|---|---|---|---|---|---|
| 3m - 6m | Q235B / ASTM A36 | 60 / 140 mm | 2.75mm - 3.25mm | $\ge 75 \mu\text{m}$ | 140 km/h (38.8 m/s) |
| 7m - 9m | Q235B / Q355B | 70 / 180 mm | 3.50mm - 4.00mm | $\ge 86 \mu\text{m}$ | 160 km/h (44.4 m/s) |
| 10m - 12m | Q355B / S355JR | 80 / 220 mm | 4.00mm - 5.00mm | $\ge 86 \mu\text{m}$ | 180 km/h (50.0 m/s) |
| 15m - 20m (High Mast) | Q355B / ASTM A572 Gr 50 | 160 / 350 mm | 6.00mm - 8.00mm | $\ge 100 \mu\text{m}$ | 220 km/h (61.1 m/s) |
| 25m - 40m (High Mast) | Q355B Heavy Structural | 200 / 560 mm (Multi-section) | 8.00mm - 12.00mm | $\ge 110 \mu\text{m}$ | 260 km/h (72.2 m/s) |

Yangzhou Xintong Traffic Equipment Group is a direct manufacturer established in 1999. We operate a 100,000 m² state-of-the-art manufacturing facility in Gaoyou City, Jiangsu Province, China. Our plant houses 7 specialized production lines covering raw steel slitting, CNC press bending, automatic submerged arc welding, hot-dip galvanizing prep, electrostatic powder coating, LED packaging, and solar street light assembly. Procurement teams and third-party inspectors (e.g., SGS, Bureau Veritas) are always welcome to conduct on-site factory audits or live video walkthroughs.
To prepare an accurate engineering drawing, structural calculation, and price proposal, please provide: (1) Mounting height (e.g., 6m, 8m, 10m, 12m), (2) Target road geometry (road width, lane quantity, pole spacing, arrangement), (3) Local design wind speed (e.g., 35 m/s, 45 m/s, or hurricane zone specs), (4) System type (All-in-One Solar, Split-Type Solar, or Grid-Connected AC), (5) Required light level/lux target or EN/AASHTO lighting class, and (6) Delivery destination port.
All pole shafts are fabricated from high-grade Q235B or Q355B steel and undergo full immersion hot-dip galvanizing (HDG) after all cutting, bending, and welding operations are completed. This process coats both internal and external surfaces with a thick molten zinc alloy layer ($86 \mu\text{m}$ to $110 \mu\text{m}$ thickness per ASTM A123 / ISO 1461). For coastal or high-pollution installations, an optional thermosetting electrostatic polyester powder coating is applied, offering complete UV resistance, salt-spray resistance over 5,000 hours, and customized RAL color aesthetics.
All-In-One (Integrated) Solar Lights: Combine the PV panel, LiFePO4 battery pack, MPPT controller, and LED module into a single compact housing. They offer rapid installation, low shipping volume, and minimal wind drag, making them perfect for residential streets, park pathways, and 4m–8m poles.
Split-Type Solar Lighting Systems: Feature independently mounted PV modules (adjustable tilt angles for max sun exposure), larger external lithium battery boxes (underground or top-mounted), and separate LED luminaires. Split systems are recommended for high-wattage highway illumination (8m–12m+ poles), low-solar irradiance regions, or tenders demanding 5+ continuous rainy days autonomy.
Pole shafts are bubble-wrapped, wrapped in woven protective fabric, or bundled with soft timber spacers between layers to eliminate paint abrasion or zinc coating scratches. Tapered conical and octagonal poles are strategically nested inside one another when appropriate to maximize container space utilization without scratching surfaces. Luminaires, solar panels, controllers, and hardware are packed in reinforced, export-grade plywood crates or heavy-duty corrugated cartons with customized foam inserts.
We provide a structural warranty of up to 20 years on hot-dip galvanized steel pole shafts against corrosion structural failure. Complete solar lighting systems (solar panels, LED luminaires, MPPT controllers, LiFePO4 batteries) carry a standard 3-year to 5-year full replacement warranty depending on project specifications. Spare parts (e.g., replacement controllers, LED modules, anchor bolts) are included with bulk orders, and technical remote engineering assistance is provided throughout the warranty period.
