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 connection
2. Slower efficiency in production
