A fiber reinforced plastics material pole for electricity power lines comprises a frusto-conical pole structure of tapering diameter and optionally tapering wall thickness from the lower end to the upper end. The structure is formed in three separate layers (37, 38, 39) all of which may vary in thickness including an inner filament wound layer (37), an intermediate layer (38) of directly longitudinal fibers (44, 45, 46) and an outer filament wound layer (39). The longitudinal fibers (44, 45, 46) extend from the lower end and terminate at certain positions (45A, 46A) along the length of the pole to gradually reduce the numbers of fibers so that only some extend along the full length of the pole. The pole is buried and has a filler material (30) to a position above the ground surface to prevent water entry. An outer layer (36) of a fire retardant resin contains a particulate erosion resisting material to protect the pole from soil erosion. The longitudinal fibers can be provided in pre-formed tapered elements (60, 70) arranged to extend longitudinally at spaced positions around the circumference of the pole with the space therebetween decreasing from the bottom toward the top.
