Key Features
High Strength Steel: Q345B steel resists heavy conductor loads and strong lateral wind forces for reliable tower performance.
Protected Against Rust: Hot-dip galvanizing ≥86μm ensures over 50 years of corrosion-free outdoor use.
Concrete Savings: Optimized lattice cuts foundation concrete by ~15%, lowering project costs.
Compact Top Design: Narrow upper structure limits conductor swing, suitable for tight corridors, agricultural land, and cross-terrain lines.
