Galvanization
The galvanization of the steel pole are under strict control. Galvanization is achieved by immersion in a molten
zinc bath(450̊) after pre-treated (dipping).
Mechanical Property
The metal supports are designed to withstand the nominal force F and the pressure of the wind V applied at 0.25m
from the top. Under these loads, the safety factor with respect to the elastic limit of the steel is larger than 1.8.
The post also resists a torque equal to (F+V) ×1m. Tests shows the load intervened when breaking is around 2
times of design load.
