High Strength Prestressed Making Mould Concrete Electric Pole 100-390mm Amitycare 9 Years CN;JIA 20% More Than 10 Years1

Prestressed circle spun concrete pole moulds is used for concrete pole making. Its mainly manufacture technology is longitudinal tension by steel wires. Then it can squeeze out the excess water in the concrete under the centrifugal force. Thus, it can greatly improve the concrete density and strength.

 In order to form concrete more quickly to meet the design strength of more than 70%, steam curing can be carried out so as to shorten the mould-releasing cycle

1. Saving a great deal of steel, about 30~70% (employing cold drawn steel wire can save 30%~60%; employing high stress steel wire can save 40%~69%). 

2. Crack resistance can increase about 3~5 times. 

3. Rigidity increases 1~3 times.

4. Reducing the cost (using cold drawn steel wire can reduce 25%~40%; using high stress steel wire can reduce 12%~21%). 

5. Good durability, can delay the existence and expansion of cracks. 

6. Protect the environment on which human beings depend on for existence, and reduce the deforestation.
