What's The Pultrusion Process?

High strength, nevertheless light-weight and straightforward to put in, Fastec International’s pultruded fiber bolstered compound (FRP) shapes are a low-maintenance, attractive, and sturdy solution to applications wherever traditional building materials cannot meet the stress of the operation.
A manufacturing method that produces continuous lengths of Fiberglass Reinforced Plastic (FRP) shapes with constant cross-sections, pultrusion pulls raw materials – a liquid rosin compound (a mixture of rosin, fillers, and special additives) and versatile textile reinforcing fibers (typically glass) – through a heated steel die with never-ending pull device so as to create a final form.
The process begins with long doffs of fibreglass roving, for longitudinal strength and improved tensile properties, that area unit then coated with fibreglass chopped strand mat to enhance transversal properties. the various rovings and fiberglass mats used within the method area unit chosen uniquely for every project so as to enhance the properties needed for the ultimate application. These reinforcements are force next through a rosin bath, that saturates them with the rosin mixture, then force through the heated die to create the ultimate, immutable  form.
