Detection and lofting apparatus 

1000KN mechanical universal testing machine ( tensile strength, yield strength, elongation, bending, shear and etc.) 

Five elements of carbon and sulfur analyzer 

The welding quality of ultrasonic flaw detector 

Hot dip galvanizing thickness measuring instrument  

Theodolite ( 5 ) -- installation verticality measuring tower with 

Rebound tester ( measurement of concrete strength) 

HP wide-format printers (1.2 meters ) - model, map use 

Load test stand 20 meters (for portable base station tower, the cable tower and some non-standard products test) 

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.
