Key Features
High Strength Steel
Q235B or Q345B angle steel carries heavy conductors and long-span tension without deformation.
Galvanized Surface
Hot-dip galvanizing ≥86μm prevents rust and reduces maintenance in outdoor conditions.
Wind Resistance
Designed for wind speeds above 50 m/s, suitable for open terrain and high-wind regions.
Lightweight Structure
Lattice design reduces self-weight, making transport and site lifting easier.
Customization Services
Height and Load Design
Tower height and structure designed based on span, conductor load, wind and ice conditions.
Material Selection
Q235B or Q345B steel selected according to strength and cost requirements.
Crossarm Layout
Crossarm size and spacing adjusted to match conductor type and voltage level.
Surface Treatment
Galvanizing thickness adjusted for outdoor environment and service life requirements.
Factory Advantages
Automated Production Lines -12 CNC angle steel lines support stable output for large-volume orders.
Precision Manufacturing -Accurate hole alignment ensures smooth on-site assembly and reduces installation time.
In-house Galvanizing -Integrated galvanizing process keeps coating quality consistent and delivery under control.
Engineering Support -Design team adjusts tower parameters based on project wind and load data.
Direct Factory Supply -Factory pricing helps reduce total procurement cost for bulk projects.
