Gaines Manufacturing: Mailboxes, Posts & Address Plaques

About Gaines Manufacturing

Gaines Manufacturing has spent 30+ years producing cast aluminum mailboxes, posts, and address plaques from U.S. facilities. Founded in 1991, the company built its reputation on construction quality that stamped-steel manufacturers don't match. In 2012, Gaines acquired Janzer Mailboxes, expanding its catalog with a modern minimalist line.Three construction details separate Gaines from standard mailbox brands:

Cast aluminum construction: Aluminum doesn't rust, warp, or degrade when surface coatings scratch. Standard steel mailboxes corrode from the finish inward. Cast aluminum holds structural integrity for decades in coastal, humid, and high-rainfall climates without repainting or replacement.

Solid brass accents: Brass hinges and latch hardware outlast zinc and die-cast alternatives at the highest-contact points on the unit. Standard mailboxes use cheaper hardware that strips and corrodes within a few years.

Magnetic door closures: Eliminates the loose, rattling doors common on stamped-steel mailboxes. Magnetic closures don't rely on friction or spring tension that degrades over time
