Steel Mailbox Mounting Post


This is our steel mailbox post.  Made from 3" x 3" steel square tubing with a welded plate for installation for any of our curbside mailboxes.  We offer two types of steel posts for mounting - please choose from the drop-down menu above.

Option 1: Set in Concrete -- This option allows you to set the post into concrete up to 18 inches. The entire length of the post is 60 inches. The post comes with a mounting plate that will align with the pre-cut holes in the Dexter or Barton mailbox. Hardware is included.
Option 2: Existing Footing -- This option is 42″ long and comes with a bolt plate for mounting to an existing footing or pavement. Installation hardware is provided for attaching the mailbox to the post.  You will need to provide your own hardware for attaching the post to the concrete.



We build and deliver this mailbox in clean raw hot rolled steel. Much like the grain in wood, this dark steel finish comes with a variety of heat marks from the raw steel cooling in the steel mill. Most people let this mailbox develop a handsome rust patina over time. The pictures show it at the tail end of this process as well as the raw steel look as we deliver it.

bullet proof post and mailbox...

this mailbox and post are a tank. my mail man says he's never seen anything like it. finished it with an alcohol cleaning. than a few applications of copper sulphate (root killer for sewer pipes). then apple cider vinegar (wet and then let dry about 5 times) and then more copper sulphate. and then flat clear coat.
