Industry Overview
Iron tower is an important infrastructure used to support power transmission lines and communication network. It is mainly applied to placing operators’ antennas and related communication equipment to improve signal transmission efficiency and network coverage area. The iron tower industry has emerged as a complementary industry to the power and communication sectors. Due to large load, iron tower is demanding on the stability of its base and overall structure. Additionally, connecting members of iron tower are fastened with rough bolts, which are fixed by shear force applied to the bolts. Therefore, there are extremely high demands for the processing precision, accuracy and quality of these components.

Fabrication Process
The iron tower sector is affiliated to metal manufacturing industry, primarily using metals such as iron, steel or aluminum to produce metal components, metal parts, steel products for construction, and similar items. Various metal fabrication processes are required during its production.
- Laser Cutting
- Laser Welding
- Bending
- Laser cleaning
SENFENG's Advantages
Iron tower provides an indispensable support for electric power and communication industries. SENFENG’s full industry chain will give huge impetus to the industry with its significant advantages in high efficiency, precision and quality.
Cut Ultra-long Workpieces
According to actual needs, iron tower is generally trapezoidal or triangular in shape, with a height of 25-40m. This task is quite challenging for traditional metalworking equipment. However, SENFENG has developed laser cutting machines and tandem CNC press brakes capable of dealing with ultra-long workpieces, meeting the practical needs of iron tower users.
Align with Tower Production Needs
During production, iron tower is consist of angle steel, round steel, steel pipe, lightweight aluminum alloy, decorative stainless steel plate or various profiles. All these metal materials fall within the processing range of our sheet and tube laser cutting machines, which can meet the vast majority of tower manufacturing requirements.
Keep Iron Tower Stable
Tower body has several sections and they are connected with each other by using bolts or welding. After welding with SENFENG laser welding machines, weld seams are aesthetically pleasing, and the workpieces are less prone to deformation. Sometimes, the welding strength even exceeds that of its base metal. When iron tower is exposed to outdoor conditions for extended periods, they can resist the erosion from direct sunlight, strong winds and heavy rain, preventing accidental breakage and extending its service life.
Achieve Intelligent Production
Tower manufacturers face diverse specifications of raw materials and numerous components throughout the production, necessitating effective management methods to standardize the entire workflow. SENFENG has introduced the concept of intelligent manufacturing to link information management system with production machines in order to facilitate communication. When production plans change, adjustment can be made swiftly, so that a fully information-based and intelligent process will run through raw material supply to shipment.
Relevant Customer Case
A leading Chinese power infrastructure company specializes in manufacturing power transmission towers and photovoltaic brackets. Before adopting SENFENG laser cutting systems, the company relied on traditional methods such as plasma cutting, drilling machines, punching presses, and manual operations, which were inefficient and limited in precision.
The introduction of SENFENG laser equipment has significantly improved both accuracy and productivity, while dramatically reducing labor and workflow transition costs. This upgrade has played a crucial role in the company’s overall effort to lower costs and enhance efficiency.
Key advantages include:
- Precision processing for angle steel, channel steel, steel tubes, and other materials used in power tower construction.
- Integrated bevel cutting (0–45°) in a single operation using a bevel laser cutting head.
- Fully enclosed gear-driven chucks with stronger clamping force, improving the overall accuracy of tower components.
- High-precision cutting and hole-making for critical parts like tower connectors, flange reinforcements, and base plates.
- Multi-functional integration—cutting, hole drilling, and marking are completed in one setup, boosting efficiency and saving labor.
- SENFENG’s proprietary control system optimizes material utilization, reducing raw material costs from the source.
By switching to SENFENG laser technology, the company now achieves faster, more precise, and cost-effective production of essential power infrastructure components.
