Talk to Our Engineer Now 1. Enhanced Structural Rigidity (2.5mm Wall & Ø140mm Base)
As mounting heights reach 5 meters, lighting columns are exposed to greater wind shear and frequently carry heavier single or double-arm luminaire brackets. This Q235B steel pole features a stepped multi-diameter configuration, expanding to a robust Ø140mm lower shaft. Combined with an upgraded 2.5mm structural wall thickness, it provides a significantly higher bending moment of inertia compared to lighter pedestrian poles.
2. Heavy-Duty 10mm Flange & Deep M16 Anchors
To safely transfer elevated dynamic wind loads into the foundation, the base connection is substantially reinforced. The structure utilizes a widened 280x280mm square flange plate with an upgraded 10mm thickness, preventing base cupping or weld fatigue. The anchoring kit includes four heavy-duty M16 foundation bolts with a 500mm embedment depth, ensuring absolute plumbness.
3. Code-Compliant Electrical Access Door
Designed for seamless integration into municipal street lighting grids, the lower Ø140mm steel shaft incorporates a precision laser-cut flush access door. This weatherproof compartment provides secure housing for DIN rails, MCBs, and terminal blocks. An internal M8/M10 grounding lug is welded directly inside the cavity, ensuring compliance with strict earth bonding protocols for public safety.
4. Dual-Layer Corrosion Protection (≥85μm HDG)
Tubular steel requires rigorous rust prevention, especially in humid or coastal areas. The entire column is fully submerged in molten zinc (Hot Dipped Galvanizing), creating a metallurgical barrier of ≥85μm (IEC/IECEE compliant). A secondary architectural powder coating (≥60μm) is applied, chemically isolating the steel to guarantee a maintenance-free lifecycle exceeding 25 years.

Urban Infrastructure Applications for 5M Stepped Poles
Operating at a 5-meter (16.4ft) elevation, this stepped tubular column bridges the gap between pedestrian lighting and roadway illumination. It provides broad photometric distribution suitable for low-speed vehicular traffic while maintaining a visually appealing human-scale presence.
Residential Avenues & Subdivisions
Illumination Strategy: A 5-meter height pushes the light source high enough to illuminate 2-lane neighborhood roads evenly, ensuring vehicular safety while preventing severe upward glare and light trespass into adjacent homes.
Structural Benefit: The upgraded Ø140mm base and 2.5mm wall thickness allow the pole to safely support modern LED cobra-head fixtures or dual decorative lanterns. The 500mm deep M16 foundation bolts keep the mast perfectly plumb in landscaped parkways.
Commercial Parking & Retail Plazas
Illumination Strategy: Retail centers and office parking lots require durable, mid-height area lighting to provide excellent security camera visibility without washing out building facades.
Structural Benefit: The heavy-duty 280x280x10mm flange plate provides substantial resistance against wind shear. The flush access door protects critical electrical breakers from tampering, and the dual-layer HDG/powder-coated finish prevents rust stains on commercial concrete bases.
University Campuses & City Parks
Illumination Strategy: Large public spaces require infrastructure that effectively illuminates wide pedestrian boulevards while blending seamlessly with tree canopies and landscaping.
Structural Benefit: The classic stepped round aesthetic is universally recognized and unobtrusive. The strictly enforced ≥85μm zinc coating guarantees the pole will endure decades of exposure to lawn sprinklers, rain, and soil moisture without structural oxidation.
