PURPOSE: To provide a coated steel driven member which has corrosionproofness without coating of conventional urethane elastomer and excellent wear resistance for drift sand containing no solvent. CONSTITUTION: A coated steel driven member comprises urethane elastomer 4 having rubber elasticity on the surface of a steel material 1 such as a steel pipe pile, steel pipe sheet pipe, steel sheet pile. Accordingly, the member remarkably has excellent wear resistance for drift sand, and hence has small wear of the corrosionproof film by wear, and maintains excellent corrosion resistance for a long period. |
