Metal Boxes Steel Interface Boxes were used long before PVC came onto the scene. Ultra-strong, fireproof, and incapable of being melted, Metal Boxes offer the greatest level of security for the do-it-yourselfer. They are somewhat more difficult to work with, and their sharp edges can take a toll on your palms after a while.
Metal boxes are strong, plus they provide a strong attachment with the stud. When attachment to the stud is a major worry, choose a metal box. Metal boxes mean you can drive strong screws into the studs, ensuring a maximum amount of holding power. It is also a good idea (but not a requirement) to use a metal box when the box will be exposed beyond your finish surface, as in exterior applications. Metal boxes will not distend, nor will they pull away from the stud when properly attached. With their high-stress points, metal boxes are often stronger than the work material built around them.
