Advantages of steel locking mailboxes

We've discussed aluminum locking mailboxes and plastic locking mailboxes. In this post I want to discuss locking mailboxes made out of steel.

Steel is a great material due to it's high strength. It will hold up better than aluminum and much better than plastic. The biggest problem with steel locking mailboxes is that they are prone to rust and corrosion.

I have seen many steel security mailboxes around my neighborhood that are only a few years old and they already have substantial rust. It is clear the manufacturers of these mailboxes do not understand what is necessary to keep the rust away on steel in an outdoor application like a locking mailbox

In another post I will talk about steel technologies and coating technologies that will help make steel mailboxes longer lasting and more rust resistant.
