Manufacturing Process

Manufactured to surpass industry specifications

USI Vibra-spun™ concrete poles provide superior strength

Unlike conventional cast poles, prestressed spun concrete poles are centrifugally cast. This process involves spinning the poles at a very high rpm, which produces poles with the highest density and strength to weight ratio of any concrete available. As a result they are more durable, longer lasting and resistant to freeze/thaw cycles and chemical agents.

USI concrete poles are centrifugally cast using our patented Vibra-spun process.
