Galvanized Tubular Steel Tower

Qingdao Anbang New Energy's galvanized tubular steel towers use high-quality steel as the base material, processed through an overall hot-dip galvanizing process, and designed with a modular tubular structure. Choose us as your manufacturer and supplier, get technical support and full customization services.

Our products feature excellent corrosion resistance, structural stability, and easy installation, making them widely used in transmission lines, substations, photovoltaic power stations, communication base stations, and other scenarios.

They can operate stably for long periods in various complex environments, serving as core support equipment in industrial infrastructure.

Core Advantages

Long-lasting corrosion resistance

Using an overall hot-dip galvanizing process with a zinc layer thickness ≥85μm, it forms both physical isolation and electrochemical protection. Even if the zinc layer is damaged, sacrificial anode protection continues to protect the steel, with an outdoor service life exceeding 30 years, suitable for coastal, industrial pollution areas, and other high-corrosion environments.

Strong load-bearing capacity

The galvanized tubular steel tower adopts ring/conical tubular structures, ensuring uniform stress, high sectional bending stiffness, and outstanding resistance to wind, earthquakes, and icing.

It can withstand level 11 winds and magnitude 8 earthquakes, with stability far surpassing traditional angle steel towers under extreme conditions.

Easy installation

Factory prefabricated segmented structure with flange bolt connections allows rapid assembly on-site without large lifting equipment, shortening construction time by 50% and significantly reducing project costs.

Wide adaptability

The compact structure of the towers saves approximately 50% of the area compared to angle steel towers, suitable for urban, mountainous, coastal, and various terrains. Heights from 5 to 150 meters can be customized to meet diverse engineering requirements.

Complete qualifications

Made with high-strength steel such as Q235B and Q355B, production meets international standards including ISO and AWS. Through strict weld inspection and zinc layer testing, the towers possess core steel structure manufacturing qualifications with stable and controllable product quality.

Product Working Principle

The core function of the galvanized tubular steel tower is to provide stable high-altitude support and protection for power lines, communication equipment, photovoltaic modules, and other components. Its working principle is divided into two parts:

Structural Support Principle

Through reasonable mechanical design, the tubular structure evenly transfers the top loads (weight of wires and equipment, wind loads, ice loads, etc.) to the tower foundation.

By utilizing the large radius of rotation characteristic of steel pipes, the structure's stiffness and stability are enhanced, ensuring the safety of the support system.

Corrosion Protection Principle

The hot-dip galvanized layer forms a dense zinc-iron alloy layer on the steel surface.

On one hand, it physically isolates corrosive mediums such as water, oxygen, and salt spray; on the other hand, zinc, as a more active metal, forms a galvanic cell with the steel, preferentially oxidizing to protect the steel.

Meanwhile, the corrosion products of zinc form a passivation film, further blocking corrosion and achieving long-term protection.

Precautions for Use

Before installation, check that the nameplate on the galvanized tubular steel tower matches the design drawings, and inspect the tower body, flanges, bolts, and other components for completeness to ensure there is no deformation or damage.

Use high-strength nylon ropes during hoisting to avoid damaging the galvanized coating with steel wires. The vertical deviation during installation should be ≤1/1000 to ensure structural stability.

The tower foundation should use a C30 concrete independent foundation with embedded anchor bolts to ensure reliable connection with the tower body. The grounding resistance should be ≤10Ω, and the effectiveness of the grounding system should be regularly checked.

Avoid welding, cutting, or other operations on the surface. If modifications are required, the galvanized corrosion protection must be reapplied.

Regularly check the integrity of the zinc coating, bolt tightness, and structural deformation. In coastal and high-corrosion areas, inspections are recommended every six months, and any damaged zinc coating should be repaired promptly.
