Why polygonal construction is preferred
The polygonal profile provides a practical combination of structural strength, tapered geometry and a clean appearance. The larger lower section provides the required support, while the upper portion is reduced to accommodate the lighting head. For large-area lighting projects, this arrangement can reduce the need for numerous conventional poles and can provide illumination from a strategically elevated position.

Published manufacturer and tender specifications show high-mast ranges extending from approximately 10–60 m, with continuously tapered polygonal construction and project-specific section dimensions.

Published specifications illustrate configurations such as 12.5–30 m masts with different section thicknesses, base plates, pitch-circle diameters and lifting capacities, demonstrating why these dimensions should be selected according to the specific mast design rather than treated as one universal standard.
Structural Design & Engineering
A high mast is a structural system, not simply a tall lighting pole. Its design needs to account for the combined effect of self-weight, lighting equipment, headframe, wind pressure, cable arrangement and site conditions.
For this reason, the following factors can be considered before manufacturing:
- Overall mast height
- Number and weight of luminaires
- Luminaire projected area
- Headframe configuration
- Design wind speed
- Terrain and installation location
- Pole natural frequency considerations
- Section thickness
- Base plate dimensions
- Anchor-bolt arrangement
- Foundation loading
- Deflection requirements
- Access and maintenance arrangement
High Mast Section Configuration
The mast can be manufactured in multiple sections depending on its overall height and transportation requirements. These sections can be designed for telescopic or slip-fit assembly at the installation site. For example, published technical data for a 16 m high mast shows a two-section configuration with 360 mm bottom OAF, 150 mm top OAF, 4/3 mm section thicknesses, a 32 mm base plate and eight M30 foundation bolts. These values are illustrative of one manufacturer’s design and should not be copied as a universal specification. This project-specific approach allows the mast to be engineered according to actual loading and site requirements.
Raising & Lowering System
One of the major advantages of a high mast lighting system is the possibility of bringing the lighting assembly down to ground level for maintenance.
A typical system may include:
- Motorised winch
- Stainless-steel wire rope
- Pulley arrangement
- Headframe / lantern carriage
- Cable management arrangement
- Locking mechanism
- Electrical control arrangement
The raising and lowering mechanism allows maintenance personnel to access lighting equipment without requiring the same type of elevated access equipment normally needed for permanently fixed high-level fixtures. Manufacturer specifications commonly include motorised winches, stainless-steel wire ropes and defined lifting capacities.
Manufacturing Process
The required height, lighting load, wind conditions and installation details are considered before preparing the pole design.
Suitable steel plates are cut according to the approved manufacturing dimensions.
The plates are accurately formed to achieve the required multi-sided tapered profile.
The formed plates are joined using controlled welding procedures. High-mast specifications commonly avoid circumferential joints in the mast sections.
Where required, individual sections are prepared for telescopic or slip-fit joining.
The bottom section is fitted with the required base plate, stiffeners and associated structural components.
The completed structure can undergo suitable surface preparation followed by hot-dip galvanizing or another specified protective finish.
Dimensional accuracy, welding, surface condition, components and assembly details are checked before dispatch.
Corrosion Protection
Because Polygonal High Mast Poles are normally installed outdoors, protection against atmospheric exposure is important. Hot-dip galvanizing is a widely specified finishing method for steel lighting structures.
The process provides a protective zinc coating over the steel surface. Depending on the project specification, both external and internal surfaces may be galvanized. Published high-mast specifications cite hot-dip galvanizing to applicable standards such as IS 4759 or ISO 1461.
Quality Inspection Points
Before dispatch, important inspection areas can include:
Inspection Area | Purpose |
Steel Material | Verify specified material grade |
Plate Thickness | Confirm manufacturing dimensions |
Pole Height | Check overall dimensions |
Polygonal Profile | Maintain required geometry |
Weld Quality | Verify fabrication integrity |
Base Plate | Check dimensions and alignment |
Anchor-Bolt Arrangement | Match approved foundation drawing |
Galvanizing | Check coating quality and uniformity |
Access Door | Verify fit and locking arrangement |
Winch Assembly | Check operational movement |
Wire Rope | Verify size and condition |
Headframe | Check fixture mounting arrangement |
