 3.Fibergalss composite profile Feature:

 Fibergalss composite profile  with a surface veil and inhibitor , all the pultruded profile  can protect glass fibers from pentrating the resin and can also increase the corrosion and UV resistance . These profile are non-magnetic and have good electrical and thermal insulation properties. Our FRP profile are stronger than Aluminum in the lengthwise direction of the profile . These profile can be easily fabricated with carpentry or metal working tools , fasten with screws , bolts and rivets or jointed we adhesies.
