Pultrusion process is an antomatic process where by constant cross section profiles are produced continously.Pultruded FRP shapes are made from densely packed continuous glass fibers wrapped by a layer of glass mat.The densen fiber core makes the shapes very tough and riged,with flexural strength and impact strength in langitudinal direction higher than those of common steel. The use of glass mat increase the transverse strengh of the shapes and to supply for with good corrosion-resistance and cracking resistanec.The specifications mentioned below are used widely and widely.
