Lattice Steel Tower
Galvanised Steel Lattice Telecom Antenna Surveillance Camera Pull Rope Wind Tower Guyed Wire Mast Tower
1. Using seamless steel tube as tower material, the wind load coefficient is small and the wind resistance is strong.
2. The tower column is connected by outer flange, and the bolt is tensioned, which is not easy to be damaged and reduces the maintenance cost.
3. The tower column is arranged in triangle shape to save steel.
4. Small root opening, small floor area, saving land resources and convenient site selection.
5. The weight of the tower body is light, and the new type of trefoil cutting board foundation can reduce the foundation cost.
6. Truss structure design, convenient transportation and installation, short construction period.
7. The tower type is designed according to the wind load curve, with smooth lines. It is not easy to collapse in case of rare wind disaster, reducing casualties of people and animals.
8. The design conforms to the national steel structure design code and tower and mast design specification, and the structure is safe and reliable
