Buying Guide

A cast aluminum mailbox post is an excellent addition to most homes. An adequately matched mailbox post can increase the curb appeal of a house and a lawn. Together with the mailbox, it serves an essential function of receiving your mail.

Keep in mind that there are different varieties of cast aluminum mailbox posts so choosing the right one can be a tricky task, so here’s a buying guide to help you with that.

A cast aluminum mailbox post may be categorized into a standard post, classic post, decorative post, or deluxe post. Knowing the pros and cons of each type is a big help in finding the right one for you.

  • A standard post is your "regular" post. There's nothing fancy with it, but it can do the job pretty well. The advantage of the standard post is it's economical.
  • If you like something that is out of the ordinary, then decorative posts may be the one you are looking for. This kind of cast aluminum mailbox post comes in a lot of design varieties, and all are aimed at enhancing the looks of your front lawn. Be wary though - these kinds of posts can get very expensive.
  • A classic post comes with a traditional look. It typically includes a lot of intricate designs and curves. It's suitable if you want that classic front yard look.
  • A deluxe post is something that is designed to hold more than one mailbox. It's a good option if you want a couple of mailboxes for different purposes.

The most common types of finish include mechanical finish, pretreatment, bright dipping, anodizing, liquid paint, powder coating, and sublimation.

  • Mechanical finish improves the surface quality of the aluminum so cosmetic additions will be more durable.
  • Pretreatment is aimed at improving paint adhesion. It also enhances the corrosion resistance of the aluminum used.
  • Bright dipping is an excellent choice if you want the aluminum to be naturally "bright."
  • Anodizing finish boosts the aluminum's exterior durability.
  • Liquid paint is sort of "baking-in" the paint color into the aluminum. Thus, it's a good finish if you don't want the aluminum's color to last for a long time.
  • Powder coating provides the similar effect of liquid paint, but without the use of Volatile Organic Compounds; which are harmful to the environment. Also, it makes the aluminum material very durable.
  • Sublimation is aimed at giving the aluminum a sort of an etched pattern. Since the pattern is "carved" directly into the aluminum, the design will be more durable.

Keep in mind that no single cast aluminum mailbox post is "perfect" for every homeowner. It's because everyone has different wants and needs. When shopping, it's important to know what factors are important to you. You also need to consider your budget. Your geographical location will also play a role as your local climate will have an impact on how the aluminum performs.
