Aluminum Mailboxes

Aluminum mailboxes are weather resistant, provide good security and are manufactured from heavy duty aluminum that provides protection from rust; providing years of usage.

The core reason most mailboxes are made from Aluminum is because of its ability to resist corrosion to the elements such as rain, snow, hail etc. The surface layer of aluminum oxide forms once aluminum is exposed to air; essentially preventing further oxidation.

Additionally it is a low density metal which is soft, durable and lightweight and has about one-third the density and stiffness of steel.
