GI HIGH MAST
POLES.
Heavy-duty high mast lighting structures engineered for expansive wide-area illumination across expressways, transport interchanges, airports, shipping ports, and industrial logistics yards.
Manufactured from high-tensile hot-dip galvanized steel with motorized winch lowering mechanisms for effortless ground-level maintenance and long-term structural reliability.
Engineered to withstand extreme wind-load forces and harsh environmental conditions, combining multi-luminaire headframe capacity with precision civil foundation anchorage.
WIDE-AREA ILLUMINATION.
BUILT FOR SCALE.
Dev Shakti India Limited (DSIL) manufactures heavy-duty Hot-Dip Galvanized High Mast Lighting Towers engineered for expansive area coverage, superior structural stability, and extreme environmental resilience.
Our high mast systems are custom-engineered for complex highway interchanges, commercial shipping docks, railway freight corridors, container terminals, airports, toll plazas, industrial refineries, and sporting arenas where high-lux uniform distribution and continuous operation are paramount.
Equipped with precision-engineered motorized winch lowering mechanisms, DSIL High Mast towers allow lighting fixtures and electrical accessories to be safely lowered to ground level for rapid, zero-risk maintenance without requiring specialized boom lifts or cranes.
HIGH MAST POLE TECHNICAL SPECIFICATIONS.
Comprehensive technical parameters across DSIL's modular High Mast tower portfolio ranging from 12 Meters to 40 Meters in height. Fabricated with high-grade steel and hot-dip galvanized in-house for long-term structural dependability.
