G.J. Lighting Tower Co. offers precision-engineered high mast poles designed to provide powerful and uniform lighting over large areas. Manufactured using hot-dip galvanized steel, these poles are built for durability, corrosion resistance, and high performance in demanding outdoor environments.
High mast lighting systems are an ideal solution for projects that require elevated and wide-area illumination, such as highways, industrial zones, stadiums, and large public spaces.
Technical Specifications – High Mast Pole
- Pole Shaft Material: Hot rolled MS plate/strip as per IS 5986 or BSEN 10025, with minimum yield strength of 355 MPa and ultimate strength of 510 MPa. Sulphur and phosphorus content ≤ 0.05%.
- Base Plate: Hot rolled MS plate as per IS 2062, Grade Fe-410.
- Foundation Bolts: High tensile steel with minimum UTS of 415 MPa.
- Wire Rope: Stainless steel, 7/19 construction, AISI 316 grade.
- Surface Protection: Hot dip galvanized (internal and external) as per IS 4759 / BSEN-1461 using seven-tank process.
Applications and Usability
High mast poles are widely used in projects where powerful and high-level lighting is essential. These poles are suitable for:
- Highway and expressway intersections
- Large industrial areas, ports, and logistics parks
- Airport perimeters and railway yards
- Stadiums, sports complexes, and large event grounds
- Public parks, town squares, and commercial complexes
- Remote or rural areas requiring large-area lighting coverage
Designed for ease of maintenance, reliable operation, and long service life, high mast poles offer exceptional lighting reach and distribution. They are particularly effective in minimizing the number of poles required in vast spaces, reducing installation costs and clutter.
