Pultruded FRP profiles are a new type of composite material made with glass fiber reinforcement as the reinforcing body and resin as the binder, with glass fiber cloth as the wrapping reinforcing layer; after thorough impregnation, the material is heated, formed and cured in a metal die and then pulled by a pulling machine. With good physical properties, they are widely used in high-strength, long-span applications.

Applications:
Greenlogy TEC pultruded FRP profiles are widely used in various applications, combining corrosion resistance, high strength, dimensional stability and light weight with thermal insulation and electrical insulation properties. Durable Greenlogy TEC profiles provide years of low-maintenance service in areas where steel, aluminum or wood components are traditionally specified. Today, these profiles are often used in highly corrosive applications that previously required stainless steel and other costly components.
