Maintenance

The hot dip galvanization treatment can increase the service life of the steel pole without the environmental 

pollution and no need for other daily maintenance. The following described types are specially designed for Africa

 Market which can meet the regulated height and load standard of France electricity power company.

 

Production

Our steel pole is bent to form to the polygonal (conical) section firstly. Then it is welded by the automatic 

submerged-arc. Then it is welded by the automatic submerged-arc welding machine.

 

Thirdly the top cap, strip and base plate will be welded to the pole. And finally other accessories (support brackets,

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
