1. Q235B Steel with 8.0mm Wall Option
To safely operate at a 20-meter height, the shaft is constructed from high-yield Q235B carbon steel, tapering from a broad Ø480mm base to a Ø220mm top. Based on specific dynamic wind load requirements, engineers can specify either a 6.0mm or an extreme 8.0mm wall thickness to support high-mass LED floodlight arrays without critical deflection.
2. Ø780mm Flange & M30 Anchor Bolts
The immense bending moments generated at the top of the 20M mast are transferred to the ground via a massive Ø780mm circular flange plate (25mm thickness). The foundation anchoring system utilizes 12 pieces of heavy-duty M30 bolts, embedded to a depth of 1800mm, guaranteeing absolute stability in typhoon-prone coastal regions.
3. HDG (≥85μm) + Powder Coating
The entire steel structure is immersed in molten zinc (Hot Dipped Galvanizing) to achieve a protective layer of ≥85μm, conforming to IEC/IECEE standards. A secondary powder coating (≥60μm) is applied to create an impenetrable barrier against saltwater spray, industrial chemicals, and UV radiation, ensuring a service life exceeding 25 years.

Critical Infrastructure Applications (20M Mast)
A 20-meter (65ft) high mast is not a standard municipal pole. With its 8.0mm maximum wall thickness and M30 anchor bolt system, it is designed strictly for high-risk, mega-infrastructure environments where failure is not an option.
Seaports & Deep-Water Container Terminals
Engineering Need: Container yards require massive vertical clearance for gantry cranes and reach stackers. They are also subject to continuous heavy salt spray and typhoon-level winds.
The Solution: The 20M height prevents operational interference. The 12x M30 anchor bolts secure the mast against hurricane-force coastal winds, while the strictly enforced ≥85μm Hot Dipped Galvanizing (HDG) coating chemically protects the Q235B steel from rapid oxidization in marine environments.
Highway Toll Plazas & Border Checkpoints
Engineering Need: Toll plazas and border crossings require exceptionally bright, shadow-free illumination across 10 to 20 wide lanes to ensure the accuracy of surveillance cameras and the safety of personnel.
The Solution: The 6.0/8.0mm wall thickness allows the mast to safely support large crown headframes equipped with dozen of 1000W+ LED projectors. This provides a daylight-equivalent lux level across the entire checkpoint without creating obstructive glare for approaching drivers.
Heavy Rail Freight Yards & Mining Sites
Engineering Need: Industrial rail yards and mining operations operate 24/7. Ground-level lighting is easily damaged by heavy machinery, and maintenance downtime halts logistics operations.
The Solution: Elevating the light source to 20 meters removes the infrastructure from the active working zone. The massive 780x25mm base flange absorbs the continuous ground vibrations generated by heavy freight trains, preventing micro-fractures in the foundation over decades of use.
