Frequently Asked Questions (FAQs)
1. What is the sturdiest mailbox post?
Wooden mailbox posts have stunning wood grain patterns and the ability to shape into any form desired. At the top of the list are wood species that have the highest rot resistance over time such as Teak, Ipe (pronounced ee-pay), or Black Locus (also called stone wood).
2. How deep should I bury my mailbox post?
The Federal Highway Administration recommends: A 4″ x 4″ wooden support or a 2″-diameter standard steel or aluminum pipe. Avoid unyielding and potentially dangerous supports, like heavy metal pipes, concrete posts, and farm equipment (e.g., milk cans filled with concrete). Bury your post no more than 24″ deep.
3. How long should a 4x4 post be for a mailbox?
You can make your own mailbox post by cutting a 4 by 4 in (10 by 10 cm) piece of wood to size. It should be around 65 inches (170 cm) in length, with the cut end sitting in the hole. Make sure your chosen mailbox post is weather-treated so that it won't rot or disintegrate in the elements.
4. Do you need concrete around a mailbox post?
Concrete will provide a strong and stable foundation; however, it isn't required. If you decide to use concrete, make sure to mix the concrete according to the package directions. Next, set the mailbox post. Use a level to ensure the mailbox post remains perfectly straight as you fill around it.
