Glass steel I-beam steel beam glass factory senior business, FRP pultruded profiles, there are many, fiberglass pipe, fiberglass pipe, glass steel rectangular pipe, fiberglass rods, fiberglass beam. The basic components of the FRP profiles for resin and glass fiber (including cloth, carpet, etc.), which is based fibers (including glass fibers, carbon fibers, organic fibers and other metals, non-metallic fiber) as reinforcing material, resin (mainly epoxy polyester resins, phenolic resins) as crosslinking agent and other auxiliary materials supplemented (primary materials: mold release agents, curing agents, catalysts, sealing mold agents, UV light stabilizers, clean-water, gel coat and other ) composite made of. It has a high temperature, corrosion resistance, high strength, low specific gravity, low moisture absorption, extending small and good insulation and a series of excellent properties.
