Galvanized Steel. This is the least expensive and least durable metal flashing material. It is not recommended in harsh climates or in contact with masonry materials or pressure treated wood. Like other galvanized products, the galvanic coating will eventually wear away exposing the underlying steel to corrosion.
How does corrosion affect the area of the metal?
The Area Effect. The rate of corrosion is controlled by the area of the more passive metal. For example, a galvanized steel nail (active) will corrode quickly if surrounded by a large area of copper flashing (passive). If a copper nail is used in galvanized steel flashing, however, the corrosion of the steel will be slow and spread over a large area, so it may not be noticeable. In each case, the active metal corrodes, and the passive metal is protected.
What is flashing made of?
Aluminum. Most residential wall flashing today is made from light-gauge aluminum “coil” stock because it is low-cost, easy to bend, and holds paint well. However, the aluminum alloy commonly used in flashings tends to pit and oxidize and pit in salty or polluted air.
