the FRP fence is mainly used in areas of muggy and rusty aloft and outdoors, acid-base corrosion, sewage treatment, sea water and fossil-fired power cooling tower etc..

 

 Pultrusion profile is a kind of compound materials which is formed by taking fiberglass as the reinforced material, and taking thermosetting resin as base, the fiberglass continuous roving enable the product to have the extremely high longitudinal strength, the fiberglass mat (continuous strand mat, knitted mat and so on) makes the product have the good transverse strength.

the thermosetting resin base is usually the unsaturated polyester resin, the vinly resin, or the epoxy resin and the phenolic resin, the resin base enable the product to have the good anti-corrosion property, the different resin enables the product to be suitable for various corrosion environment, to add the ultraviolet inhibitor and fire retardant may enable the product to have the outstanding anti-aging property and the different rank anti-flammable property.

 

Add the nexus mat on the product surface could make it obtain best corrosion-resistance and anti-ageing properties. the fiberglass content in piltrusion profile is usually 45%-75% (weight ratio), the balance is resin and additive. Unsaturated polyester resin and vinly resin are the most commonly used resin base.
