Taking FRP channels as the example, FRP pultruded channel is composited by glass fiber and resin matrix. Glass fiber plays a reinforcing role, it has high tensile strength and elastic modulus. For commonly used resins, the tensile strength of glass fiber is about thirty times the tensile strength of the resin, and the elastic modulus of glass fiber is about twenty times that of the resin. Therefore, the tensile strength and rigidity of FRP channes are mainly determined by glass fiber. This is also one of the reasons for the distortion of the finished products produced by some workers without knowing the glass fiber.

In addition, the compression strength, bending strength and electrical properties of FRP channel steel have nothing to do with the glass fiber, but are related to the performance of the resin. The factors that glass fiber has a greater impact on the performance of glass fiber reinforced plastics are the type, content, length and orientation of the fiber. The uniformity and spacing of the fiber diameter and distribution are the secondary reasons that affect the mechanical properties.

Therefore, high quality FRP channels are produced by high content of glass fiber and high quality resin. Nantong Mach’s has been committed to the production and sales of FRP pultruded profiles for 15+ years. The glass fiber content of FRP pultruded profiles is as high as 80%, and the resin can also be selected according to the use situation. The appropriate choice can make the properties of finished products more prominent and applicable, while minimizing your costs.
