Features of Power Transmission Towers
Structural Design: Angle Steel Truss
The power transmission towers utilize a spatial truss structure; by distributing loads across multiple directions, they maintain overall structural stability even under conditions of high wind speeds and heavy loads.
Corrosion Protection: Hot-Dip Galvanizing
A protective zinc coating is formed on the surface, effectively isolating the structure from moisture and oxidative environments, thereby extending its service life to 30–50 years.
Assembly System: Bolted Connections
Featuring a fully bolted structural design, the towers boast a high degree of factory pre-assembly, enabling rapid on-site erection without the need for extensive field welding.

Quality Control

Incoming Raw Material Inspection
Power transmission towers utilize Q235B, Q355B, and Q420B steel grades. Prior to acceptance into the facility, every batch of steel undergoes testing for chemical composition and tensile strength to ensure full compliance with IEC and GB standard requirements.
Steel Dimensions and Thickness Verification
Before cutting operations begin, the thickness of steel plates and angle steels is precisely measured. Thickness tolerances are strictly controlled within ±0.3 mm to guarantee structural load-bearing consistency.
CNC Cutting and Punching Precision Inspection
Utilizing advanced CNC cutting and punching processes, the positional tolerance for every connection hole is controlled within ±0.5 mm, ensuring smooth and trouble-free bolt installation at the construction site.
Component Welding Quality Inspection
Welding joints are fabricated using CO₂gas-shielded welding. All weld seams undergo visual and penetrant testing to ensure they are free from cracks, porosity, and fusion defects.
Hot-Dip Galvanizing Coating Thickness Inspection
Component surfaces undergo hot-dip galvanizing treatment. The thickness of the zinc coating is controlled within the range of 80–100 μm to ensure stable, long-term corrosion resistance.
Component Trial Assembly Inspection
Sectional trial assemblies are conducted at the factory to verify the precision of structural connections within the tower body, ensuring that all bolt hole positions align perfectly for on-site installation.
Marking and Numbering Verification
All components are managed via a comprehensive coding system. Prior to shipment, each component's code is cross-referenced against the engineering drawings to prevent mix-ups during on-site assembly.
Final Structural Acceptance Inspection
A comprehensive quality review is conducted prior to shipment—covering dimensions, galvanizing quality, and structural consistency—to confirm full compliance with project delivery standards.
