PURPOSE:To prevent the corrosion of metal and concrete by a method wherein thermoplastic resin is stuck, in the form of a film, on a flexible base material to form a sheet and, after a substance to be coated is heated, the sheet is wound thereon with pressure. CONSTITUTION:Thermoplastic resin is stuck, in the form of a film, on a flexible base material such as a metal plate, an aluminum sheet or a metal net to form a sheet. Next, a substance to be coated is heated to a temperature exceeding the melting point of the thermoplastic resin, and then said sheet is wound with pressure on said coated substance for corrosion proof. Polyethylene, vinyl chloride resin, polystyrene, polypropylene or the like can be used as the thermoplastic resin. In addition to metal and concrete, this corrosion proof method of plastic coating can be applied also to timber, paper, etc. to which corrosion proof processing can not be applied heretofore, by devising a method of heating, e.g. by using far-infrared irradiation or the like.
