Qingdao Altai Tower Co., Ltd. has successfully completed the factory trial assembly of a 30-meter, 4-legged radar support tower. Executed for a major North African telecommunications infrastructure project, this pre-shipment fit check verified the structural integrity, bolt alignment, and critical dimensional tolerances of a 54.5-ton prototype tower before hot-dip galvanizing and final dispatch. H2-1: What the Trial Assembly Covers: 2mm Leveling and Zero Site Modification For this specific radar support tower project, the trial assembly was not merely a visual check. It was a stringent dimensional verification aligned with the client's approved Inspection and Test Plan (ITP). The assembly verified the following critical metrics: · Overall Leveling Tolerance: The fully assembled 30m prototype tower was verified strictly within a maximum leveling tolerance of 2mm, ensuring structural plumbness. · Bolt Alignment and Fit-up: All tower members, connection nodes, and accessory bolts were fitted without interference or distortion. · Zero Site Modification Rule: The contract strictly prohibits any cutting, drilling, reaming, or grinding to correct fabrication errors during assembly. This trial successfully validated that all parts fit perfectly without the need for field modification. H2-2: 30m 4-Legged Radar Tower: Key Design Parameters The radar support towers under production are designed for severe environmental conditions and heavy payloads. Key parameters verified during the trial assembly include: · Tower Type: 30m 4-legged self-supporting lattice structure. · Unit Weight: A minimum of 54,500 kg per tower, reflecting the heavy-duty steel required for radar stability. · Galvanization & Anti-Corrosion: Components are thoroughly prepared before assembly. Post-assembly, the steel will undergo hot-dip galvanizing with a minimum coating thickness of 85 μm at any measurement point. · Accessories Integration: The assembly included the fit-check of anti-falling devices, copper earthing tapes, lightning rods, and aviation tower lights. H2-3: Why Factory Trial Assembly Matters for Radar Installations Radar towers are often installed in remote or critical infrastructure sites where on-site adjustments are costly and compromise structural integrity. Conducting a full trial assembly at our manufacturing facility in Qingdao mitigates these risks:   · Risk Transfer: Identifies fabrication or hole-alignment issues at the factory stage, rather than on the construction site in Libya. · Zinc Coating Protection: By validating the fit-up before galvanizing, we ensure that no post-galvanizing cutting or drilling (which exposes raw steel and causes rust) is required on-site. · Third-Party Verification: The entire trial assembly was witnessed and approved by an independent third-party inspection company, ensuring objective compliance with international standards. Q & A Q: What is the acc...

A customer from Burkina Faso visited our factory for the factory acceptance inspection of the 12M light-duty Cellular on Wheels (COW). This COW is designed to achieve a lightweight design while meeting structural strength requirements. Its chassis platform is equipped with an equipment compartment, a battery/power compartment, and a solar photovoltaic (PV) power system, together with a small generator as backup power. The lifting mast and telescopic outriggers are controlled by a hydraulic system and support three control options: wired control, wireless remote control, and hydraulic joystick control. The PV panel brackets are designed to be rotatable and adjustable to meet power-generation requirements at different times of day. The small backup generator can independently supply power to the full equipment set and is equipped with a 15 L fuel tank. The customer was satisfied, confirmed that the acceptance inspection was passed, and the unit is ready for shipment.  

A new shipment of telecom tower components has been loaded and is ready for transport to the United States. This consignment includes galvanized accessories—such as cable trays, fastening kits, and antenna mounting kits—as well as non-galvanized steel components (including stamped identification plates and access ports for monopoles). To ensure structural integrity and prevent damage during transit, all items are packed using steel frames reinforced with wire mesh. The hot-dip galvanizing process strictly adheres to the ASTM A123 standard, with a coating thickness exceeding 100 microns for all materials with a thickness of 6 mm or greater.  

This week, Mr. Oscar from Venezuela visited our company, touring our angle-steel towers, tubular towers, monopoles, laboratory, and hot-dip galvanizing workshop. As his primary procurement interest lies in angle-steel towers, he conducted a detailed inspection of the raw materials, auxiliary materials, punching processes, and plasma-cutting operations used for these structures. Mr. Oscar also thoroughly examined our quality control procedures—including the testing of incoming raw materials (such as tensile and impact tests) and the measurement of coating thickness following the hot-dip galvanizing process—and expressed his satisfaction with what he observed.

Installation has begun on a 25-meter Radar Support Tower destined for the Solomon Islands. Following the completion and curing of the concrete foundation, the client promptly commenced the installation process; our company is providing remote guidance for the assembly of certain complex components. The radar tower is expected to be fully assembled this month and put into service within the year.  

Our factory has completed the production, hot-dip galvanizing, inspection, and export packing of a 30m self-support lattice communication tower for a client in Djibouti. The tower is fabricated from Q355B steel, hot-dip galvanized to ASTM A123, and packed with non-woven fabric and steel strapping to ensure safe delivery by sea. This project further demonstrates our capability to manufacture and export custom lattice communication towers for African and coastal markets.  

This week, our Moroccan client visited the site to inspect the hot-dip galvanized integrated communication shelter. They conducted a detailed examination of the surface finish, weld seams, hydraulic system, lifting mechanism, and other components; all passed inspection. Additionally, due to changing requirements, the client requested some further modifications, such as adjustments to the cable routing and extensions for the mounting poles. The client also toured a large-scale mobile telecom base station, showing great interest in the product and gathering information for future procurement.

Several custom-made Integrated Communication Shelters for a Moroccan client have completed hot-dip galvanizing and surface grinding, and have undergone trial operations. During testing, the power supply, electrical, and hydraulic systems all functioned correctly; the units will be painted following the client's personal inspection and acceptance in China.  

Our company has completed the packaging and shipment of the foundation components for 18 radar support towers destined for a client in Libya. Production of the 18 towers is scheduled for completion by the end of the year. In accordance with the client's requirements, the foundation sections were manufactured and shipped first to allow for the completion of foundation construction at the project site, ensuring that installation of the radar support structures can commence immediately upon their arrival.  

Recently, based on feedback from our Solomon customers, the radar support towers we manufactured have been delivered to the construction site and unloaded. The foundation is now nearing completion. Next month, our company will send technical personnel to the site to guide the installation.  

A new batch of telecom tower components has been packaged and boxed for shipment to the United States. Some high-precision products are packaged in wooden boxes for differentiation. The remaining products are packaged in sea freight-appropriate packaging.  

Today we completed the trial assembly of a 500kV power transmission tower before hot-dip galvanizing. Trial assembly has verified that all components are within the minimum tolerance range. This type of tower is supplied to the State Grid Corporation of China, and the raw material testing, trial assembly, and hot-dip galvanizing all meet national standards.
