PROBLEM TO BE SOLVED: To provide a corrugated galvanized plate easily placed into a winding attitude and easily cut, and a protective wall using the corrugated galvanized plate, easily installed in linear or curved shape. SOLUTION: The corrugated galvanized plate 11 is formed in rectangular shape on the whole with its corrugated direction formed along a longitudinal direction A. Since the corrugated galvanized plate has a ridgeline direction of crests and troughs of corrugation in the short side direction of the rectangular shape, elastic resiliency is small, and winding in the corrugated direction (longitudinal direction) can be easily performed. In the maintained state of the winding attitude, transportation by manual operation or by vehicle can be easily performed by one person. The corrugated galvanized plate can be cut in required length for use, and cutting work can be easily performed in flat shape in the short side direction B along the ridgeline of crests and troughs of corrugation. The protective wall 1 using the corrugated galvanized plate is constituted by fixing the corrugated galvanized plate to a fence body 2 provided on the ground side, placing the longitudinal direction laterally and the short side direction B vertically.
