Self Supporting Galvanized 4 Legs Angle Steel Tower Telecommunication Lattice Tower
The angle steel or steel pipe is used as the tower column material, which has small wind load coefficient and strong wind resistance. The tower column is connected by outer flange plate, and the bolt is tensioned, which is not easy to damage, and reduces the maintenance cost. The triangular layout of the tower column saves steel, follows small, covers small area, saves land resources, and has convenient site selection, light weight of the tower body, convenient transportation and installation, short construction period, and the tower type changes with the wind load curve, Smooth lines, not easy to collapse in case of rare wind disaster, reduce human and animal casualties. The design conforms to the steel structure design specification and tower and mast design specification, and the structure. Effective service life: more than 50 years.
Performance characteristics: 1. Tower verticality: 1% ‰
2. Design wind speed: 25m / s-35m / S
3. Grounding resistance: ≤ 4 Ω
4. Permitted ice binding of Tower: 5-6mm
5. Anti damage ability: wind level 10
6. Anticorrosion treatment: hot zinc anticorrosion treatment / cold zinc anticorrosion treatment / paint painting
