Profile :
Pultrusion technology is a method of producing FRP profiles continuously by putting the glass roving and other continuous glass reinforcement mat，polyester surface mat,etc saturated by resin into the die that can maintain the specific section, and made it.
Raw material：
★Reinforcement material: Roving, mat, continuous mat, surface veil and stitched veil.
★Matrix material: Unsaturated polyester, epoxy resin, vinyl ester, etc.
Characteristic of the pultruded profiles：
★Good corrosion resistant, anti-ageing
★Good water-proof and flame retardant
★Strong, light, anti-impact
★Good dimension stability
★Good Insulation and magnetic penetration
★Good prearrange
★Long life service, free of maintenance
★Easy and quick installation
Application：
★Electronic & electric appliances, cable tray, insulation rod in transmitter and motor, optical cable tension member, antenna case for cell phone replay station, electrical insulated ladder, rail protection plate, tools handle etc.
★Chemical industry Pipeline support, structure, gratings, rails, bridge, operation platform, oil extraction rod, pressure pipe, guide roller, ladder, demister and external support for tanks and vessels.
★Construction market Protection system for extra large bridges, moving houses, moving working platform, windows frame, light weight bridge, roofing, computer lab, green house structure etc.
★Infrastructure Anti-reflection boards on highway，light post，water/sewage treatment, support for large cooling tower and corrosion sealing system for large bridges
