Wide Range of Applications
It can be installed in a load-bearing capacity of the roof, ground or slopes.
The arrangement of equilateral triangle form and fixation of guyed strand,greatly reduce the weight of the tower; small wind load factor, simple foundation forms, small footprint (typically 0.25m × 0.25m), little damage for the load-bearing object, convenient construction of floor base, can be designed to multi-platform, high carrying capacity, can be mounted multiple antennas and microwave transmission equipment; when constructing in floor, the guyed fixation are made easily for many maintenances of the structures around the floor, greatly accelerate the speed of construction;when constructing in hillside,make the guyed fixation taking advantage of hillside, convenient to install, rapid construction progress, light component, small footprint, little damage for the load-bearing object.
Triangular telecom tower
Bespoke Telecom tower could be fabricated as per GB, EN or ASTM standard with high quality.
