Galvanized Steel Pipe Transmission Tower

Qingdao Anbang New Energy's Galvanized Steel Pipe Transmission Towers use Q355B/Q420 high-strength steel pipes as the base material, processed through an overall hot-dip galvanizing process, and designed with conical/multi-sided tubular structures.

They offer advantages such as excellent corrosion resistance, structural stability, efficient installation, and compact land use. The products are widely used in urban power grids, mountain transmission, coastal, and industrial pollution areas, capable of long-term stable service in extreme environments, and are core supporting equipment for modern transmission projects.

Product Advantages

High Durability

Galvanized steel pipe transmission towers adopt overall hot-dip galvanizing, with a zinc layer thickness ≥85μm, forming both physical isolation and electrochemical protection.

Outdoor service life exceeds 30 years, suitable for harsh environments such as coastal areas, high salt fog, and industrial pollution.

Stable structure

Tubular sections have uniform stress distribution and high bending stiffness. Wind resistance coefficient is 20%-40% lower than angle steel towers.

Can withstand level 11 strong winds, magnitude 8 earthquakes, and heavy ice loads, with excellent stability under extreme conditions.

Efficient construction

Factory-prefabricated segmented structure with flange bolt connections allows rapid assembly on-site without large-scale lifting equipment.

Construction time is reduced by 50%, significantly lowering project costs.

Wide adaptability

Galvanized steel pipe transmission towers have a compact structure, saving about 50% of land compared to traditional angle steel towers.

Suitable for narrow urban plots, mountains, coastal areas, and other complex terrains, customizable in heights from 5 to 150 meters.

Reliable quality

Made from high-strength steel, production meets national standards such as GB 50545 and DL/T 5154, with full-process quality control including weld inspection and zinc layer testing. Fully qualified, stable performance.

How to Choose the Model

Select by Voltage Level

10kV–35kV: Use single-circuit galvanized steel transmission towers, height 15–30m, wall thickness 6–10mm, suitable for urban and park low-voltage lines.

110kV–220kV: Use double-circuit / multi-circuit galvanized steel transmission towers, height 30–60m, wall thickness 10–16mm, meeting medium- and high-voltage transmission needs.

500kV and above: Use special ultra-high voltage galvanized steel transmission towers, height 60–150m, wall thickness 16–20mm, suitable for long-span, ultra-long distance transmission.

Selection according to environmental conditions

Coastal / High Corrosion Areas: Choose high-corrosion-resistant galvanized steel transmission towers with a zinc coating ≥100μm to enhance salt spray resistance.

Strong Wind / Seismic Areas: Select reinforced structures, optimize cross-section and wall thickness to improve wind and earthquake resistance.

Mountainous / Complex Terrain: Choose lightweight, narrow-base galvanized steel transmission towers to accommodate transportation and installation conditions.

Selection according to functional purposes

Straight Towers: Used for straight sections of the line, bearing vertical and horizontal wind loads.

Tension / Angle Towers: Used for line direction changes and tension conversion, bearing unbalanced tension.

Terminal / Crossing Towers: Used for the start/end of the line and for crossing rivers or roads, requiring higher load-bearing capacity.

Precautions for Use

Before installation, check that the nameplate of the galvanized steel transmission tower matches the drawing parameters, and inspect that the tower body, flanges, and bolts are free of deformation or damage, ensuring all accessories are complete.

Use nylon ropes for lifting to avoid scratching the galvanized coating; the vertical deviation during installation should be ≤1/1000, and flange bolts should be tightened according to torque to ensure a reliable connection.

The tower foundation should use a C30 concrete independent footing with embedded anchor bolts, and grounding resistance should be ≤10Ω. Regularly test the effectiveness of the grounding system.

Welding or cutting on the surface of the galvanized steel transmission tower is strictly prohibited. If modification is required, it must be reapplied with hot-dip galvanizing for corrosion protection.

Regularly check the integrity of the zinc coating, bolt tightness, and structural deformation; in coastal/high-corrosion areas, inspect every six months and promptly repair any damaged zinc coating.

Non-professional personnel are strictly prohibited from climbing the galvanized steel transmission tower. Warning signs such as "High Voltage Danger, Keep Away" should be placed around the tower, maintaining a safe distance.
