FRP Pultrusion Process: Resin bathing, shaping, and final product

The Pultrusion Process

High strength, yet lightweight and easy to install, Fastec International’s pultruded fiber reinforced polymer (FRP) shapes are a low-maintenance, attractive, and durable solution to applications where traditional building materials cannot meet the demands of the operation.

A manufacturing process that produces continuous lengths of FRP shapes with constant cross-sections, pultrusion pulls raw materials – a liquid resin compound (a mixture of resin, fillers, and special additives) and flexible textile reinforcing fibers (typically glass) – through a heated steel die with a continuous pulling device in order to form a final shape.

The process begins with long doffs of fiberglass roving, for longitudinal strength and improved tensile properties, which are then covered with fiberglass mat to improve transverse properties. The different rovings and mats utilized in the process are chosen uniquely for each project in order to improve the properties required for the final application. These reinforcements are pulled next through a resin bath, which saturates them with the resin mixture, and then pulled through the heated die to form the final, immutable shape.

The basic pultrusion process looks like this:

Benefits of Pultruded FRP Products

Used in place of traditional building materials, such as steel, aluminum, and wood, Fastec International’s pultruded FRP products can save you time, money, and energy. From industrial cooling towers to recreational and marine areas, Fastec’s versatile, attractive, and long-lasting fiberglass products are lightweight, easy to assemble, and will not corrode, chip, rust, or mildew.

In environments that are corrosive, exposed to the elements, or high-temperature, Fastec International FRP can provide stability, strength, and safety. Our products can be designed to suit your exact needs, from the resin we use in the pultrusion process to the size, shape, and color of the finished product.

In short, Fastec International’s FRP products are:

  • Corrosion resistant
  • Nonconductive
  • Lightweight
  • Strong & Stable
  • Nonmagnetic
  • Nonsparking
  • Easy to install with commercial tools
