Plastic Mailbox Designs

In my last post I talked about some of the advantages and problems with an aluminum locking mailbox design.

In this post I want to talk a little bit about plastic mailbox designs. There are not very many plastic mailboxes that are locking. There are some other plastic mailbox designs out there.

The advantage is that they will never rust. The disadvantage is that sometimes when exposed to lots of sunlight, they end up fading and looking very bad. Also, in climates where the temperature gets very cold, they can be susceptible to cracking. Even worse, in very cold temperatures, it would be easy for somebody to break your mailbox with a bat or crowbar.

Also, plastic designs typically do not look as good as metal designs because the plastic must be thicker to meet he US Postal service standards.
