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.
