Reinforcement fibers may be roving, continuous mat, woven roving, carbon or others. The fibers are impregnated with a polymer matrix (resin, minerals, pigments, additives) and passed through a pre-forming station that produces the stratification necessary to give the profile the desired properties. After the pre-forming step, the resin-impregnated fibers are pulled through a heated die to polymerize the resin.   2-FRP Profile Properties Light Weight - Less Density - 20% Of Steel;70% Of Aluminum High Strength And Insulating Values High Corrosion Resistance UV Resistant Inhibited Variety Of Colors For Choice Superior Dimensional Stability Wide Temperature Range Use Consistent Cross Section Lasting Performance Good Tenacity Excellent Structural Properties Environmentally Safe Non-Conductive Thermally And Electrically Dimensional Stability Non-Magnetic Electromagnetic Ease Of Fabrication & Installation                   c
