FRP Pultrusion Rectangular tube/Channel beam/Angle beam/Round tube : Series of our pultrusion profiles include square tube,rectangular tube,round tube,angle, I- beam,channel,rod and other custom profiles. After proper combination and connection,they could be widely used in many fields such as:FRP grating platform,walkways,ladder,guardrail,supporting structure of cooling tower,sporting profiles,tool handles and other load structure,etc. Pultrusion process is a mechanized process of FRP composites,involves pulling a collection of fibers in the form of roving,mat or fabric through a resin bath and then through a heated die to cure the resin,and then take shapes of profiles. Advantages of pultrusion profiles: 1.Anti-corrosion and anti-ageing 2.Very designable 3.Light weight and high strength 4.Easy of cutting and installation 5.Non-magnetic,non-conductive 6.Abundant color for choice Application: FRP bridge profile FRP farming profile FRP structural profile FRP cooling tower profile Fiberglass crossarm
