How do you prevent the12 ft. 5V Crimp Galvanized Steel 29-Gauge Roof Panel from rusting?
Galvanized panels exposed to chemicals or near salt water have a tendency to oxidize much quicker.
This is a steel panel with a Galvanized coating, Galvanization (or galvanizing as it is most commonly called in that industry) is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The zinc acts both as a physical barrier for the metal and as a chemical one. Since zinc is more reactive from an electrochemical perspective, it also acts as a sacrificial anode, meaning that it will draw all corrosive effects onto itself to spare the metal beneath. While the protective coating is effective, it can and will eventually cease to be. Galvanized panels exposed to chemicals or near salt water have a tendency to oxidize much quicker. Properly cleaning galvanized metal not only keeps it looking new, but also keeps the zinc oxide barrier strong and intact. To maintain your factory-applied finish so it will last for many years, a minimum routine cleaning of at least once a year (or as necessary) is recommended. The cleaning routine will vary depending on geographic area, environmental conditions and the coating finish. In areas of high industrial areas, it is recommended that cleaning occur at least twice per year. In most cases, simply washing with plain water (also referred to as sweet water and tap water) using a hose will be adequate. The water used should be not be salt water or from a water source that has a high salt content. However, in areas where dirt collection is heavier or mildew has occurred, the following solution is recommended to remove these build-ups: 1/3 cup dry powdered detergent (such as Tide®) 2/3 cup tri-sodium phosphate (such as Soilax®) 1 quart sodium hypochlorite 5% solution (such as Clorox®) 3 quarts water Note: It is advisable to use rubber gloves when handling this solution. A stiff bristle brush may be useful for embossed metal. To minimize streaking, always wash from the bottom to the top. A clean water rinse (also referred to as sweet water and tap water) should follow immediately. Strong solvents and abrasive type cleaners should be avoided to prevent any permanent damage to the finish. Remove caulk compounds, oil, grease, tars, wax and similar substances with mineral spirits only to those affected areas. Follow with detergent cleaning and clear water rinsing. Be sure to rinse thoroughly.
