15M High Mast Light Pole Q235B Carbon Steel HDG Manufacturer

Model: DL01-A01F03-001 This 15-meter (50ft) high mast light pole is engineered for stadiums, airports, and large intersections. Fabricated from Q235B carbon steel, it features a base diameter of Ø350mm, a top diameter of Ø150mm, and a structural wall thickness of 5.0mm or 6.0mm. The mounting base utilizes a Ø560mm circular flange plate with a thickness of 20mm to secure the high-mass structure. For long-term environmental protection, the steel undergoes Hot Dipped Galvanizing (HDG) with a zinc coating ≥85μm, followed by a powder coating ≥60μm, ensuring structural integrity for over 25 years.

Features

1. Q235B Carbon Steel Construction (15M)

The 15-meter mast is constructed from high-tensile Q235B carbon steel. It is formed into a conical structure tapering from Ø350mm at the base to Ø150mm at the top. Depending on the project’s specific dynamic wind load analysis, clients can select between 5.0mm and 6.0mm wall thickness options to support multiple heavy stadium floodlights.

2. Hot Dipped Galvanized (HDG) Protection

To meet IEC/IECEE standards, the steel shaft undergoes a complete Hot Dipped Galvanizing process, achieving a zinc coating thickness of ≥85μm. This is followed by a surface powder coating of ≥60μm, preventing internal and external steel oxidation and guaranteeing >25 years of corrosion resistance.

3. Ø560mm x 20mm Base Flange

Foundation anchoring is managed by a heavy-duty circular flange plate measuring Ø560mm in diameter and 20mm in thickness. This thick base plate is fully welded to the shaft, distributing extreme bending moments and wind sheer forces into the concrete footing.

Applications

Infrastructure Applications for 15M High Masts

Engineered from Q235B carbon steel, this 15-meter structure is deployed in locations requiring broad area illumination and high equipment load capacities.

Sports Stadiums & Arenas

The 5.0/6.0mm wall thickness allows the mast to support circular or rectangular headframes carrying multiple 1000W+ LED floodlights, providing shadow-free lighting for football and cricket fields.

Airport Aprons & Seaports

Marine and aviation environments require strict corrosion control. The ≥85μm HDG zinc coating ensures structural integrity against salt spray and jet exhaust over a >25-year lifecycle.

Highway Interchanges

The 20mm thick flange plate secures the 15M mast firmly at complex highway interchanges, maximizing ground lux levels while minimizing the number of poles required near traffic zones.
