What Galvanic Corrosion on Building Facades Can Lead To
Galvanic corrosion is typically caused when two dissimilar metals are improperly coupled together in a corrosive environment. This common problem is seen in almost every structure, including commercial facades.
Galvanic corrosion is caused by an electrochemical reaction between different classifications of metals rubbing against each other in wet or grimy conditions. This type of corrosion commonly occurs between aluminum and cast iron; copper and steel; and stainless steel and aluminum.
