CONCRETE POLES

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

How to Specify a Spun Concrete Pole | StressCrete Utility Poles

The NESC has determined the strength factor for concrete as 1.0 compared to 0.65 and 0.85 for wood in Grade B and Grade C construction, respectively. This strength factor is especially important when converting wood poles to spun concrete poles so that the wood pole is replaced with a concrete pole that is designed to the appropriate strength.

PRECAST CONCRETE PROCESS – theconstructor

PRECAST CONCRETE PROCESS. A large number of concrete structures (about 6% of the building frame market) are precast.

a testament to the value of spun concrete. But the power of spun concrete poles isn't just in their ability to resist extreme elements. Lower prices, simple installation, virtually no maintenance concerns and line sizes up to 345 kV (single or double circuit) make spun concrete a nearly perfect pole material. Backed by decades of

DIRECT BURIAL Spun Concrete Poles

Spun Concrete Poles Spun concrete poles are generally direct buried eliminating the need for expensive anchor base footings.
