Custom Light Pole Contractors Manufacturers & Factory

Yangzhou Xintong Traffic Equipment Group is a verified direct manufacturer founded in 1999. We own and operate a 100,000 m² heavy manufacturing facility in Gaoyou, Jiangsu, China. Every phase—from raw sheet laser cutting, CNC bending, and automatic seam welding to full-immersion hot-dip galvanizing, electrostatic powder coating, and LED fixture assembly—is conducted in-house across our 7 dedicated production lines. EPC buyers and third-party inspectors (e.g., SGS, Bureau Veritas) are welcomed for on-site or live video facility audits.

We fabricate primarily from high-grade structural steels Q235B and Q355B, which cross-reference directly to international grades: ASTM A36, ASTM A572 Grade 50, and European EN 10025 S235JR and S355JR. With every export shipment, we supply certified EN 10204 Type 3.1 Material Test Reports (MTRs) documenting accurate carbon equivalents, tensile strength, yield points, and elongation percentages traceable back to the raw casting heat number.

Our structural design calculations follow the AASHTO Standard Specifications for Structural Supports for Highway Signs, Luminaires, and Traffic Signals and EN 40-3-1/3-3. Our engineers simulate total Effective Projected Area (EPA), dynamic vortex shedding, and gust factors up to wind speeds of 210 km/h (58.3 m/s). Finite element analysis verifies that the base-plate thickness, anchor bolt diameter, and circumferential weld joints remain well below structural yield limits under full mechanical deflection.

Poles are completely degreased, acid-pickled, fluxed, and fully submerged in a molten zinc bath maintained at 440°C–460°C per ASTM A123 and ISO 1461. This forms metallurgical intermetallic zinc-iron alloy layers providing both external and internal protection. Minimum coating thickness exceeds 86 μm (610 g/m²), and can be customized over 120 μm for aggressive marine environments (ISO 12944 C5-M). For architectural color matching, we apply electrostatic TGIC polyester powder coatings cured at 200°C for exceptional UV and salt-spray durability.

Yes. Our in-house engineering team provides end-to-end lighting calculations. When supplied with your road cross-section, lane count, pavement classification (e.g., CIE R1–R4), and target lux or luminance class (M1 to M6, P1 to P6), we build full 3D DIALux evo simulations. The generated report includes isolux contours, overall uniformity ($U_0$), longitudinal uniformity ($U_l$), and glare limitation ratings ($TI$), ensuring approval by municipal road authorities.

To produce an exact bid-ready submittal and quotation, please share: 1) Mounting height and arm outreach length; 2) Design wind speed or regional project location; 3) Number and weight of luminaires, fixtures, or auxiliary equipment (EPA calculation); 4) Pole shape preference (octagonal, round conical, square); 5) Power supply scheme (grid AC vs standalone solar PV autonomy days); and 6) Target delivery seaport and required Incoterms (FOB, CIF, DDP).
