132kV Galvanized Angle Steel Transmission Tower

With the rapid development of industrialization and urbanization, the demand for stable and efficient medium-high voltage power transmission is increasing, and 132kV power grids have become the backbone of regional power supply due to their balanced transmission capacity and cost. Anbang is a manufacturer in China that can cooperate with you for your new project.

As the key carrier of 132kV power transmission, 132kV Galvanized Angle Steel Transmission Towers directly determine the safety and reliability of the power grid. Among various types of transmission towers, galvanized angle steel towers are widely adopted for their standardized production, low cost, and strong adaptability to complex terrains such as mountains and coasts.

The hot-dip galvanizing process effectively solves the corrosion problem of steel structures in harsh environments, extending the service life. 

Product advantage

1. Structural Strength & Stability

Our 132kV Galvanized Angle Steel Transmission Tower is made of high-quality angle steel such as Q235, Q345, Q425, with outstanding tensile, compressive and bending resistance.

Lattice truss structure is lightweight yet highly rigid, effectively resisting strong winds, ice coating, earthquakes and other extreme loads.

Designed in accordance with international and national standards, providing high safety redundancy and long-term operational reliability.

2. Hot-Dip Galvanizing Anti-Corrosion Performance

Adopts hot-dip galvanizing process, forming a dense zinc-iron alloy layer with strong adhesion for all-round corrosion protection.

Outstanding weather resistance ensures a service life of 30–50 years even in harsh environments like coastal salt spray, industrial pollution, acid rain and plateau areas.

Low maintenance cost, almost no need for repainting during operation, greatly reducing later maintenance expenses.

3. Economical & Convenient Construction

Factory prefabrication and on-site bolt assembly enable fast construction, short project period and low labor cost.

Standardized components are easy to transport, process and replace; damaged parts can be repaired individually.

Optimized overall cost with moderate initial investment and ultra-long service life.

4. Environmentally Friendly & Reliable Quality

Steel material is 100% recyclable, green and environmentally friendly.Complete quality certificates, in line with ISO 9001 and international power transmission standards.

Stable performance, suitable for long-distance and high-reliability power grid projects.
