High Quality Angle Steel Tower Manufacturer

Qingdao Anbang is a professional manufacturer of New Energy Angle Steel Tower, which is the core steel structure product of the company for overhead transmission lines ranging from 10kV to 750kV. As the most widely used and cost-effective transmission tower type in the current market, it features an angle steel truss assembly structure as its core design, capable of stably supporting several tons of conductor and ground wire weight.

It maintains structural stability under extreme conditions such as strong winds, heavy snow, severe cold, extreme heat, heavy ice, and long spans, serving as critical infrastructure for cross-regional energy transmission, power delivery from new energy bases, and the construction of the national backbone grid.

Relying on Qingdao Anbang's full-chain solution capability from design, manufacturing, inspection to delivery, the angle steel tower not only meets conventional transmission needs but also can be customized and optimized for new energy projects, special geographical environments, and overseas projects, balancing structural strength, installation efficiency, corrosion resistance, and full lifecycle cost, providing users with safe, reliable, and long-lasting transmission support.

Product Positioning and Core Value

Qingdao Anbang New Energy Angle Steel Tower is positioned as a main high-voltage / ultra-high-voltage transmission tower, covering core scenarios such as new energy grid connection, backbone grid construction, long-distance cross-regional transmission, and transmission in harsh environments.

Its core advantages are high strength, high stability, low cost, and easy installation, helping users reduce structural deformation and tipping risks, cut maintenance and replacement costs, and fully comply with national and international transmission equipment standards, making it a preferred product for both new energy power delivery and traditional grid upgrades.

Its core value lies in the use of high-strength steel and precision manufacturing processes to ensure long-term operational safety; combining standardization and customization to meet various project requirements; proprietary hot-dip galvanizing corrosion protection system greatly enhancing service life; and full-process quality control with authoritative certification, eliminating usage risks.

Product Structure and Technical Features

1. Structural Form

The angle steel tower adopts an angle steel segment assembled truss structure, assembled by standard angle steel components connected with bolts, eliminating the need for complex on-site welding. Its lightweight design ensures both structural rigidity and ease of transportation, suitable for long-distance transport and installation on complex terrain.

2. Material Selection

Strictly selected Q355B and Q420B high-strength structural steels, possessing excellent tensile, compressive, and impact resistance, capable of withstanding composite loads in large spans, heavy ice zones, and strong wind areas, meeting the stringent requirements of 750kV ultra-high-voltage transmission. All steel materials come with national-level inspection reports, ensuring quality traceability.

3. Processing Precision

Adopts CNC automated processing equipment, with hole positions and dimensional tolerances controlled at the millimeter level. The components fit highly accurately and align precisely, requiring no secondary corrections on-site, effectively shortening construction time, reducing labor costs, and minimizing rework.

4. Anti-Corrosion Technology

The company operates its own hot-dip galvanizing plant, with zinc layer thickness far exceeding national standards. Anti-corrosion performance leads the industry, able to withstand harsh environments such as coastal salt spray, desert wind and sand, high humidity, and chemical corrosion, significantly extending tower service life and reducing full-cycle maintenance costs.
