protection of zinc-aluminum coated
The alloy coating on Zinc-Aluminum steel provides optimum galvanic protection and exhibits a combination of :
1. The durability of aluminum coatings
2. The sacrificial protection offered by zinc
3. The Zinc/Aluminum alloy coating provides
galvanic protection to bare steel edges by a similar mechanism to galvanized coatings. One way this has been tasted is shown below where coating of similar thickness on Zinc-Aluminum and zinc coated steel have been removed to the-steel base using scribe marks to the atmosphere.
