Pultruded sheet piling is a section of piling that is manufactured by the continuous processing of raw materials by pulling resin-rich reinforcements through a heated steel die to form profiles of constant cross section of continuous length. The first reinforcement utilized in the profile arelong continuous glass fibres referred to as “roving”. Glass roving runs the length of the pultruded profile and gives the shape its “longitudinal strength”. To add multidirectional reinforcement, continuous glass “matting” is added. The roving and matting is now pulled through a resin bath where the glass fibres are saturated with a liquid thermosetting resin. This process is typically referred to as the “wet-out” process.
The coated fibres are now assembled to the proper shape by a forming guide and finally drawn through a heated (curing) die. Once exiting the die, the pultruded shape is cooled and the resulting high strength, reinforced composite sheet piling is cut to length.
Pultruded sheet piling is suitable for a wide variety of applications for light bulkheads. As is the case with vinyl sheeting, deflection is frequently the controlling factor in design, although the strength of the material is several times higher than vinyl.
