1. High-Yield Polygonal Cross-Section
Manufactured via heavy-duty press-braking, the multi-faceted polygonal geometry significantly increases the structural moment of inertia compared to cylindrical alternatives. Fabricated from Q235B carbon steel, this folding technique maximizes longitudinal yield strength, preventing critical deflection under aerodynamic drag at the 9-meter elevation.
2. Ø188mm Base & 14mm Thick Flange Plate
To safely handle elevated dynamic wind loads, the structural profile is widened to a Ø188mm base diameter, tapering to a Ø80mm top. Shear forces are transferred to the foundation through an upgraded 350x350mm square flange plate with a solid 14mm thickness. The wall thickness is engineered at 3.5mm, with an optional 4.5mm upgrade available for extreme wind zones.
3. Service Door & Grounding System
The lighting column is equipped with a flush-mounted service door to house standard municipal electrical control gear. Precision laser-cut to maintain shaft integrity, the internal cavity includes a welded grounding lug, ensuring strict compliance with public earth bonding codes to eliminate electrical fault risks.
4. IEC Compliant Galvanizing & Coating
The raw steel structure is fully submerged in molten zinc (Hot-Dip Galvanizing), depositing a metallurgical barrier with a minimum thickness of ≥85μm (IEC/IECEE compliant). A secondary architectural powder coating (≥60μm) is subsequently applied, chemically isolating the pole from road salts, industrial pollutants, and UV radiation for a 25+ year lifespan.

Urban Infrastructure Applications for 9M Polygonal Poles
Reaching 9 meters (30ft), this polygonal lighting column is specifically engineered for multi-lane traffic environments and large-scale commercial intersections requiring extended photometric reach.
Multi-Lane Urban Arterial Roads
Illumination Strategy: For 4-to-6 lane city carriageways, a 9-meter elevation is required to push the light distribution deep into the center lanes, ensuring optimal horizontal illuminance for high-speed transit.
Structural Benefit: The widened Ø188mm base diameter provides the torsional rigidity needed to support heavy double-arm outreach brackets, positioning high-wattage LED cobra heads directly over the right-of-way without wind-induced swaying.
Major Highway On-Ramps & Intersections
Illumination Strategy: Wide intersections demand high vertical illuminance and overlapping beam patterns to ensure drivers can identify traffic signals and merging lanes from extended distances.
Structural Benefit: The heavy-duty 350x350x14mm flange plate secures the system firmly against both severe dynamic wind loads and continuous harmonic vibrations generated by heavy freight traffic.
Industrial Park Perimeters
Illumination Strategy: Logistics hubs and factory perimeters require robust, maintenance-free boundary lighting capable of withstanding industrial emissions and severe weather.
Structural Benefit: The dual-layer HDG (≥85μm) and powder-coated surface completely seals the Q235B carbon steel from oxidation. This ensures structural integrity for over 25 years, drastically reducing lifecycle operational costs for facility management.
