Pultruded FRP profiles are composite materials made from fibers (such as glass or carbon) and a polymer matrix (usually epoxy, vinyl ester, or polyester resin) that are pulled, or "pultruded," through a die in a continuous process. This results in a product with high strength-to-weight ratio, excellent corrosion resistance, and thermal stability.
These profiles are commonly used in construction, infrastructure, and industrial applications where traditional building materials like steel, wood, or concrete might not be as suitable due to limitations such as weight, maintenance, or corrosion. Pultruded FRP profiles come in various shapes and sizes, such as I-beams, angles, channels, round and square tubes, and flat panels. The specific profile and design are often customized to fit the specific requirements of a particular application.
