This is a photograph of the lower gates of Walter F. George Lock, the highest lift lock in the Mobile District.  This lock was put into service in 1956.  The coating system on the accessible areas of the gates and the impressed current cathodic protection systems have been consistently maintained since construction.  As a result of the good maintenance performed on the gate corrosion control systems, this facility has only been dewatered once--10 years after it opened.  It was in such good condition that it was put back into operation and has not been dewatered since (there has been no need to dewater it again).  The original coating is on the gates below the water line.  This example serves to illustrate the benefits that can be obtained with the proper implementing and maintaining of corrosion control methods (primarily good coating systems and cathodic protection systems).  The intent and purpose of this website is to illustrate why the Corps of Engineers needs corrosion control and where it is required by law and/or regulation, the results of improper corrosion control, the benefits of proper corrosion control, and to present information on the publications and personnel where design and other corrosion control information can be obtained.  If proper corrosion control techniques are implemented and maintained, corrosion on our buried and submerged military metallic structures and on our civil works hydraulic steel structures (as well as other civil works structures, owned and maintained by the government, such as buried fuel tanks, water tanks, etc.) will be minimized.  Subsequently, money will be saved, safety will be enhanced, adverse legal and environmental impacts will be reduced, and the resulting corrosion prevention benefits will far outweigh their costs.  Mobile District has prepared two power point slide presentations, one aimed at our military audience (Cathodic Protection Requirements for Military Projects) and one for our civil works audience (Corrosion Control of Hydraulic Steel Structures.)  These presentations provide a quick overview of the corrosion control and cathodic protection systems’ requirements for various structures for which the Corps is responsible.  Please take a moment to review one or both of them.
