GAOERJI STEEL
Search
GAOERJI offer customized steel tower solutions that meet international standards and ensure structural stability in extreme environments through the hot-dip galvanizing process and precise geometric design. GAOERJI as a vertically integrated source manufacturing plant, skip intermediate trade links, provide you with highly competitive direct sales prices and faster flexible production lead times.
Steel tower for sale is mainly used for long-distance power transmission, 5G signal base station construction, meteorological observation monitoring and super high-rise radio and television signal transmission.
The surface of the steel tower is treated by a fully automated hot-dip zinc pool, and the thickness of the zinc layer is stably maintained above 85 microns. This ensures that the structure will not rust for 50 years in harsh outdoor environments such as salt spray and acid rain, reducing later operation and maintenance costs by about 60%.
all the nodes of the tower body are locked by grade 10.9 friction type high-strength bolts, with strong shear resistance. This 1 configuration solves the pain point of fatigue cracking of traditional welding points and ensures that the steel tower still maintains geometric accuracy under strong wind vibration environment.
through CNC hydraulic punching and plasma cutting technology, to ensure that the tower section connection hole position error control within 0.5mm. After installation, the overall verticality tolerance is better than 1/1000, which ensures the accurate pointing of the high-frequency antenna transmitting signal.
scientific lattice fluid dynamics shape is adopted, and the wind load resistance coefficient is 35% lower than that of solid structure. This lightweight design reduces the load on the tower foundation without sacrificing strength, saving about 15% of the foundation civil construction budget.
all components are trial assembled and coded before leaving the factory. The optimized sub-size fits perfectly into standard containers, not only reducing cross-border transportation losses to zero, but also increasing the efficiency of on-site installation by about 40%.
the tower body integrates built-in safety ladder and multi-layer high-load working platform, each layer can bear more than 500kg. This not only facilitates the mounting and installation of multi-band devices, but also ensures the security of core assets through the physical anti-theft structure.

For telecommunications giants responsible for 5G/6G base station distribution, mobile network coverage and signal expansion in remote areas. The large-capacity mounting capacity of the GAOERJI steel tower can effectively support the multi-band equipment tower and reduce the single-point construction cost.
engineering units that undertake the construction of national power grids and trans-regional high-voltage transmission lines. Our high-strength transmission towers pass rigorous mechanical load tests to ensure the safe operation of the line under extreme freezing and wind loads.
For procurement departments that need to mount high-definition cameras, weather monitoring sensors or forest fire monitoring equipment. Light and flexible single tube tower or landscape tower can be perfectly integrated into the city and natural environment.
for airports, ports and highway construction parties that need to erect high-pole lights and navigation signal towers. Rugged and durable corrosion-resistant properties ensure that these core transportation hubs do not require frequent downtime for maintenance during long-term service.
provide free CAD structure deepening and wind load simulation calculation before sales; Provide detailed 3D installation instruction manual after sales. If the project needs, the GAOERJI can send senior engineers to the site for guidance and promise to provide 10-year special quality assurance for structural quality defects.
The expected service life of this steel tower product is 50 years. The main maintenance work focuses on the regular inspection of the preload of the connecting bolts and the settlement of the foundation. Due to the use of deep anti-corrosion process, the tower body does not need to be painted twice in most natural environments.
