Polygonal Tapered Steel Monopole – High-Voltage Power Transmission Solutions
Space-efficient urban distribution infrastructure engineered for 10kV-220kV transmission lines. Hot-dip galvanized Q345B/Q460 steel construction with 50-year design life.
Engineered for Southeast Asian Urban Infrastructure
The Xytower Polygonal Tapered Steel Monopole represents the optimal solution for high-density urban power distribution across Malaysia, Myanmar, and Thailand. Our 12-sided polygonal design maximizes structural efficiency while minimizing land footprint—a critical advantage in Southeast Asian metropolitan areas where land acquisition costs continue to rise.
Built at our ISO 9001:2015 certified facility with 1,000+ skilled technicians, each monopole undergoes rigorous quality control including 100% ultrasonic weld testing and dimensional verification to ±2mm tolerance. Our China Southern Power Grid partnership validates our engineering standards for the most demanding transmission applications.
Minimal Land Acquisition
Single-point foundation reduces land requirement by 80% vs lattice towers—critical for Myanmar/Thailand urban corridors
Anti-Corrosion Protection
Hot-dip galvanization ≥86μm (ASTM A123) or ≥100μm (ISO 1461) with optional polyurethane coating for coastal Malaysia environments
Flexible Connection Options
Slip-joint (inner sleeve) or flange plate connections—field-proven across 150+km of Malaysian transmission corridors
Seismic Zone Engineering
Designed for Zone 2-4 earthquake regions per UBC/IBC standards—essential for Myanmar and Thailand geological conditions
