Flanged Polygonal Monopole Tower
MF-Series
IEC 60652 Certified · Wind Speed Rated 45m/s · Hot-Dip Galvanized 80μm+
Engineered for Southeast Asian Infrastructure
The MF-Series Flanged Polygonal Monopole Tower represents Xytower's advanced engineering solution for high-voltage transmission and heavy telecommunications loads in challenging tropical environments. Our proprietary 8-to-12-sided polygonal geometry reduces aerodynamic drag by 15% compared to conventional cylindrical poles, critical for installations in typhoon-prone regions of Malaysia, Thailand, and the Philippines.
Designed for 66kV through 220kV transmission lines, the MF-Series features precision CNC-machined flanges with high-strength friction grip bolted connections (Grade 8.8/10.9), enabling rapid field assembly without specialized welding equipment. The slip-joint or flanged connection options accommodate varying site constraints and foundation specifications, while the tapered steel shaft optimizes material utilization and bending moment distribution.

Engineering Design Features
Advanced structural solutions for demanding environments
Polygonal Geometry
Our 8-to-12 sided polygonal cross-section reduces wind load coefficient by 15% compared to conventional round poles. The faceted design disrupts vortex shedding patterns, minimizing oscillation during high-wind events common in Southeast Asian monsoon conditions.
Flange Connection System
High-precision CNC-drilled flanges with serrated washers ensure uniform load distribution and prevent bolt loosening under cyclic loading. Each flange undergoes 100% dimensional inspection with CMM verification to ±0.5mm tolerance.
Anti-Corrosion System
Double-layer hot-dip galvanizing with optional polyurethane coating provides superior protection in coastal Thailand and Malaysia environments. Zinc coating exceeds ASTM A123 requirements with 610g/m² minimum mass per surface area.
