<p>A method for manufacturing a shape steel using waste materials and a shape steel produced by the method are provided to prevent environmental contamination by manufacturing a shape steel with improved strength and resistance against corrosion from waste materials including waste vinyl or waste fiber. A method for manufacturing a shape steel, comprises a step of producing a composite resin(34) by mixing a combination of waste vinyl molten by heat and waste fiber 80 to 95 weight% and a hardening agent 5 to 20 weight%; a step of inserting a metal reinforcement plate(32) into a frame having a desired shape; a step of injecting the composite resin into the frame; and a step of compressing and cooling the composite resin injected into the frame.</p> |
