Custom Split Solar Street Light Factories & Exporter Engineering Resilience

Yangzhou Xintong Traffic Equipment Group is a direct OEM/ODM manufacturer established in 1999. We own and operate a 100,000 m² industrial production campus in Gaoyou, Jiangsu Province, China. Our facilities house 7 fully mechanized production lines covering raw steel CNC plasma shearing, 14m tandem hydraulic bending, submerged automatic arc welding, dedicated hot-dip galvanizing baths, automated electrostatic powder coating lines, and cleanroom SMT/solar assembly workshops. Buyers and third-party inspection firms (SGS, TÜV, Bureau Veritas) are welcomed for physical or live video factory audits.

Our products are engineered to comply with EN 40-5 (lighting columns), ASTM A123 / ISO 1461 (hot-dip galvanization specifications), and AASHTO Standard Specifications for Structural Supports for Highway Signs, Luminaires, and Traffic Signals. Structural calculations take into account local basic wind speeds (up to 160 km/h or gusts up to 60 m/s), dead loads, and soil anchor shear. We furnish comprehensive mill test certificates (EN 10204 3.1), galvanizing thickness inspection reports, and full DIALux lighting photometric studies with each tender submission.

Highway bids mandate high mounting heights (8m to 12m) and wide optical throws delivering 20 to 50 Lux with strict uniformity (U0 > 0.4). This requires luminaire outputs between 9,000 and 22,000 lumens. Integrated all-in-one lights cannot house the large photovoltaic area (300W–550W) or the battery capacity needed to sustain that wattage through 3–5 cloudy days. Furthermore, split lights allow the PV array to tilt independently toward the true solar meridian while pointing the luminaire directly across the traffic lanes, maximizing energy harvest by up to 40%.

We utilize high-grade Q235B and Q355B low-silicon structural steel that responds optimally to hot-dip galvanizing. Following acid pickling and fluxing, the poles are completely immersed in molten zinc at 450°C, forming an iron-zinc alloy layer chemically bonded to the steel with a minimum thickness of 86 microns (up to 120 microns upon request). For harsh coastal environments (ISO 12944 C5-M marine rating), we apply a duplex protective system combining hot-dip galvanizing with an electrostatically applied, thermoset architectural-grade polyester powder coating cured at 200°C.

To prepare a turnkey tender submission, please specify: 1) Roadway cross-section (lane count, width, median presence); 2) Illumination target (CIE lighting class or lux target); 3) Installation pole height or distance spacing; 4) Local design wind velocity (m/s or km/h); 5) Autonomous backup days required (e.g., 3 to 7 overcast days); 6) Project site location or GPS coordinates for solar radiation modeling; and 7) Order quantity along with designated destination port. Our engineering department returns turnkey CAD drawings and DIALux simulations within 24 working hours.
