 For years, protecting steel from corrosion typically involved either the use of hot dip galvanizing or some type of paint system. However, more and more corrosion specialists are utilizing both methods of corrosion protection in what is commonly referred to as a duplex system. A duplex system is simply painting or powder coating steel that has been hot dip galvanized after fabrication. When paint and galvanized steel are used together, the corrosion protection is superior to either protection system used alone. In fact, many tests have shown that a duplex system lasts from 1.5 to 2.5 times the normal combined lifetimes of both the zinc and the paint systems.
