Steel mold for precast concrete pole

The manufacturing process involves spinning the moulds at high speed while pouring concrete into them. The centrifugal force generated by the spinning process compacts the concrete and removes any air bubbles, resulting in a dense and strong pole. The poles are then cured under controlled conditions to ensure their strength and durability.

Prestressed concrete poles are preferred over traditional concrete poles because they have higher strength-to-weight ratio, longer lifespan, and require less maintenance. They are also more resistant to weathering, corrosion, and fire. The use of prestressed concrete poles also reduces the carbon footprint of the manufacturing process, making it an environmentally friendly option.

Prestressed circle spun concrete pole moulds come in various sizes and shapes to accommodate different pole dimensions and designs. They can be customized to meet specific requirements.

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.
