Pultrusion is the process by which BRP manufacturers its composite profiles.

Pultrusion is a continuous process used to manufacture structural shapes with a constant cross section. The process starts with creels of fiberglass unidirectional roving and continuous filament mat are pulled first through performing guides, this is the first step in shaping the reinforcements. During the second step the roving and mat are drawn through a resin bath where the reinforcements are saturated or “wet out” with a thermoset resin typically polyester or vinyl ester. Polyester surfacing veil is now added to the combination of glass and resin just before it enters the heated steel die for final shaping and curing. BRP uses caterpillar style “pullers” to pull the finished part to the cutoff saw where it will be cut to the desired length. The end result is a high-strength profile ready for use when it leaves the pultrusion machine. Pultruded products provide designers and engineers with the benefits of high strength-to-weight ratios, corrosion resistance, excellent dielectric properties, and dimensional stability.

Woven roving, stitched fabrics or other types of reinforcements such as carbon and aramid fibers may be used to enhance physical properties of the composite profile

Pigments, fillers, and other special ingredients may also be added to the resin to give the profile color, fire resistance, and increased weatherability.

Besides pultrusion BRP offers secondary fabrication of our pultruded products. We have a full service fabrication center outfitted with the latest in CNC equipment. We also offer design and assembly support.
