Method of modular pole construction and modular pole assembly
A method of modular pole construction an elongate modular pole structure is disclosed. A first step of the method involves providing hollow pole section modules, each module having an elongated structure with a base end and an opposed tip end. The modules are stacked to form an elongated modular pole structure of a selected length by mating the tip end of a base module with the base end of an additional module. One or more than one of the modules forming the elongated modular pole structure comprise a composite material having fire resistant properties.
