Drawing and extruding sectional material is drawn, squeezed and manufactured by coated glass fibrofelt with continuous glass fiber, emerged into unsaturated resin£¨ or epoxide resin and PF resign£©. It is very tough and firm, whose absolute values of longitudinal flexural strength and impact strength have exceeded those of common steel material. Its merits include excellent corrosion resistance, high temperature resistance and insulating properties. The operation life of products in acid and alkali medium is longer, and its utilization scope in industrial and civil field keeps enlarging and more and more welcomed by people.
