Four Legged Angular Telecommunication Tower
Tubular tower appeared year 2001 in China. The main pier is made from tubular, auxiliary part made from pipe and angel steel.
The advantage of tubular tower:
1. Reduce the weight by 10%–20%
2. Reduce the wind press of the tower
3. Larger 20% rotation radius than angel tower.
4. Larger load capacity than angel tower.
5. Reduce 10%–20% material
6. Shorten preiod install
7. Structure diversification
The shortage:1. More complex structure connection2. Slower efficiency in production
