Abstract
An elongated, substantially rigid member suitable for use as a marine piling is formed by feeding a substantially solid plastic core into a die and continuously extruding a molten plastic into the die so that the molten plastic surrounds and bonds to the plastic core and to reinforcing bars fed into the die at positions surrounding the plastic core. The plastic core acts as a heat sink to facilitate cooling of the molten plastic and deters bending of the member while cooling.
