Talk to Our Engineer Now 1. Heavy-Duty 3.0mm Wall & Expanded Base
At a 7-meter (23ft) elevation, lighting poles act as massive levers against wind shear. This Q235B steel mast is structurally upgraded with a heavy-duty 3.0mm wall thickness. The stepped tubular geometry features a significantly widened Ø165mm lower shaft and an expanded Ø114mm upper section, providing the extreme bending stiffness required to support heavy multi-arm LED roadway fixtures without deflection.
2. Enlarged 320mm Flange & M18 Anchor Bolts
To safely transfer elevated overturning moments into the concrete footing, the foundation connection has been radically reinforced. The structure utilizes an oversized 320x320mm square flange plate (10mm thick). The anchoring system is upgraded to four heavy-duty M18 foundation bolts with an extreme 700mm embedment depth, locking the mast permanently against dynamic wind gusts in open parking lots.
3. Secure Electrical Access Compartment
Designed for immediate integration into municipal grids, the lower Ø165mm steel shaft incorporates a precision laser-cut flush access door. This weatherproof compartment provides spacious and secure housing for DIN rails, breakers, and terminal blocks. An internal M8/M10 grounding lug is welded directly inside the cavity, ensuring strict compliance with local earth bonding protocols.
4. HDG (≥85μm) & Architectural Powder Coating
Tubular steel deployed in commercial zones requires uncompromising rust prevention. The entire assembled column is fully submerged in molten zinc (Hot Dipped Galvanizing), creating a metallurgical barrier of ≥85μm. A secondary heat-cured architectural powder coating (≥60μm) is applied, chemically sealing the steel to prevent corrosive bleed onto concrete bases for over 25 years.
Commercial & Municipal Roadway Applications for 7M Poles
Operating at the highly sought-after 7-meter (23ft) elevation, this heavy-duty stepped tubular column is the absolute gold standard for expansive area lighting and primary municipal routes. It is specifically engineered to safely carry multi-head fixture arrays.
Mega-Retail Parking Lots & Auto Dealerships
Illumination Strategy: Vast commercial parking facilities require 7M poles to elevate high-wattage LED shoebox fixtures, casting massive pools of overlapping light to ensure pedestrian safety and security camera clarity.
Structural Benefit: The upgraded 3.0mm wall thickness and expanded Ø114mm top tenon effortlessly support the heavy weight and wind drag of triple or quad-arm luminaire brackets. The deep M18 foundation anchors keep the mast rock-solid in completely unsheltered, windy lots.
Primary Municipal Roadways & Intersections
Illumination Strategy: A 7-meter height provides excellent downward lux and longitudinal uniformity across wider 3-to-4 lane urban avenues and complex traffic intersections.
Structural Benefit: The heavy-duty 320x320x10mm flange plate prevents structural fatigue caused by continuous vibration from passing heavy-duty trucks. The internal grounding lug and flush door ensure strict compliance with municipal electrical safety codes.
Industrial Complexes & Port Terminals
Illumination Strategy: Logistics hubs and industrial access roads require intense, reliable area lighting to guide 24/7 freight operations safely.
Structural Benefit: The Q235B steel structure is incredibly resilient. Crucially, the rigorous ≥85μm Hot Dipped Galvanizing guarantees that exposure to harsh industrial emissions or coastal salinity will not compromise the column’s structural integrity.
