We provide lifecycle, one-stop customization services:
We specialize in the design, fabrication and supply of high-strength, highly reliable full-range steel transmission towers (electricity pylons), providing standardized and customized tower solutions for global transmission and distribution networks, renewable energy projects and grid upgrades. Our towers strictly comply with international design codes, adopt advanced manufacturing processes and long-term anti-corrosion technologies, and ensure safe, stable and durable support structures for power lines in various complex environments and harsh climate conditions, serving as the cornerstone for building modern smart grids.
Features & Core Advantages
Superior Structural Safety & Reliability
Designed using Limit State Design and validated by full-scale tests, our towers have ample safety margins under extreme loads. Refined FEA optimizes load paths, eliminating stress concentrations for whole-life service safety and minimized operational risk.
High Degree of Standardization & Modularity
Our extensive standard tower type database quickly matches most line projects, shortening design time. Modular component design maximizes fabrication, packing, shipping, and erection efficiency, reducing overall cost and schedule.
Strong Environmental Adaptability & Customization
We provide enhanced designs for heavy icing, high wind, seismic, coastal corrosion, and high-altitude areas. Customize multi-circuit, compact, strain, angle, dead-end, and long-span towers for complex terrain and narrow corridors.
Full-Process Quality Control & Traceability
Strict QC at each stage: material inspection, CNC cutting, auto-welding (tubular), HDG, trial assembly. Unique ID codes on main members enable full traceability, supporting grid asset management.
Rapid Delivery & Global Project Support
Modern production lines and supply chains ensure on-time delivery for large orders. We offer EXW, FOB, CIF, DAP terms, assist with logistics, and provide erection manuals, bolt-tightening diagrams, and field technical support.

Core Specifications & Technical Parameters
|
Parameter |
Specification Range / Standards |
Technical Notes & Considerations |
|
Design Codes |
IEC 60826, ASCE 10, BS EN 50341, GB 50061, Local Standards |
Perform load combination, limit state, and fatigue design per local codes for structural safety. |
|
Voltage Level |
10kV to 1000kV+ AC, ±800kV HVDC |
Covers full spectrum from distribution to UHV AC/DC transmission. Tower type varies with voltage and circuit number. |
|
Structure Type |
Lattice Angle Tower, Tubular Tower, Hybrid Tower, Monopole (Polygon Steel Pole) |
Lattice towers are economical; Tubular towers have lower wind drag for long spans/heavy icing; Poles suit urban corridors. |
|
Main Steel |
Q235B, Q345B, Q420B, Q460C; ASTM A36, A572 Gr.50; EN 10025 S355, S460 |
Select based on stress. High-strength steel reduces weight. Strict control of impact toughness (cold regions). |
|
Corrosion Protection |
Hot-Dip Galvanizing (Avg. zinc ≥86μm), Thermal Spray Zn/Al, Heavy-duty Coatings |
HDG is the most cost-effective long-term solution (30+ years). Enhanced protection for coastal/industrial areas. |
|
Connection |
High-Strength Bolting (GB/T 1231, ASTM A325/A490) |
All-bolted for fast field erection and quality control. Anti-loosening measures provided. |
|
Design Loads |
Wind, Ice, Broken Wire, Erection, Seismic |
Precise load calculation based on local weather/geology. Special attention to differential ice loading and galloping. |
|
Tower Height |
15m - 100m+ (Self-supporting) |
