1) high strength
2) light weight
3) anti-corrosion
4) anti-aging

   FRP square tube is light weight, high strength, anti-corrosion, electric insulation.So in some area it has advantage over metal.

    Fiberglass square tube (frp square tube) is the thermosetting plastic products combining the reinforced materials of fiberglass roving, surfacing mat, polyester or vinyl ester etc. Fiberglass square tube (frp square tube) is a kind of composite material, but also a kind of composite structure. It maybe designed as per applications, also per the required mechanical strength and appearance. It is made by pultrusion.

    As other fiberglass profiles, fiberglass square tube (frp square tube) has the following characteristics:

   1) high strength

   2) light weight

   3) anti-corrosion

   4) anti-aging

   5) thermal and electric insulation and acoustic insulation

   6) easy to be installed and treatment

   7) free to select the size and the color

   So in some area, fiberglass square tube (frp square tube) has advantage over metals and can instead it.

    The fiberglass square tube (frp square tube) can be used in the fields of  chemical anti-corrosion, construction, electric insulation, power development and telecommunications etc.
