PROBLEM TO BE SOLVED: To provide a corrosion protecting device for steel-made equipment providing an excellent corrosion protecting property over a long period to various steel-made equipment installed on the ground even if used in a high snowfall region, a region of heavy salt damage, etc. SOLUTION: The corrosion protecting device for the steel-made equipment has a buried part to be buried in the ground when installed on the ground and an aboveground part to be allowed to appear at the surface. Further, the corrosion protection device which is composed of zinc or zinc alloy, aluminum or aluminum alloy, or magnesium or magnesium alloy and functions as a sacrificial anode with respect to the equipment can be energizably and detachably attached to practically the whole periphery of the part close to the root of the aboveground part. Moreover, the main body of the corrosion protection device is formed so that its thickness is larger on the ground side than on the upper-end side, or the main body of the corrosion protection device has, at its end on the ground side, a flanged part projecting toward outside along the ground. |
