PURPOSE:To improve the durability of a steel sheet pile by sticking a coating sheet composed of a thermally adhesive binder layer and a cross-linking plastic layer closely on the surface of a preheated steel sheet pile. CONSTITUTION:The coating sheet with a plastic layer is supplied on the surface of a steel sheet pile, pressure is applied to the surface of the coating sheet to be deformed in the form of U-section and the coating sheet deformed in the U-form is pushed against the surface of the heated steel sheet pile. The steel sheet pile 1 has a body with a U-form section and a joint part 14 bent outward on the flange parts 13 of both sides. The coating sheet 4 preferably consists, for examle, of an adhesive layer with adhesive temperatures 50-200 deg.C and a plastic layer with a melting point exceeding that of the binder. The outermost layer of the steel sheet pile with such constitution has heat resistance, shock resistance, weather resistance, durability and can resist against corrosion for a long period. |
