How to Put Up a Mailbox on a Steel Fence? 8 Steps To Follow

Step 1: Choose the Right Mailbox

Not all the mailboxes are mounted on a steel fence so one must select this according to requirements. Here's what to look for:

  • Material: For an outdoor use mailbox, choose one that is made of stainless steel or other a weather resistant plastic. This will make it able to stand competition that come along with outdoor conditions.

  • Size: Think about the amount of mail you possibly engage with regularly. Larger packages can be a problem if you receive them frequently: thus, a bigger mailbox is needed.

  • Style: It is advisable to select a color that will match the color of the fence and your home. Oh, and also if the mailbox that you’ll be installing has not holes for screws, you should know that some mailboxes have holes premade for easier installation of screws.

Step 2: Decide on the Placement

However, selecting a perfect place to install your mailbox is crucial more especially when it comes to ease of accessing your mails as well as when dooring your car.


  • Height: The height of a mailbox is best set at a range of 41 to 45 inches above the ground. This is because at this specific height the mail carrier can conveniently place the mailbox while putting it at a level where small animals cannot get at it.

  • Position: Mount the mailbox where mail can be delivered with little or no interference into the compound of the homeowner. It should be mounted on a flat section of the fence in order to not become loose and move around.

  • Local Regulations: There are certain rules concerning the placement of a mailbox in some areas. For more information on height or placement restrictions, refer to the postal service of your country.

Step 3: Mark the Mounting Points

After choosing the right location, it is now the right time to locate where the mailbox will be fitted.

  • Measure and Mark: Locate the position of the mailbox with the help of measuring tape. With this, identify the points where the mounting brackets or screws will go by drawing circles on them with the pencil or marker.

  • Level It: Make sure the base of mailbox is smooth and the top of the box is dead level. Before you start drilling use a level to make sure that the marks you have placed are still correct.

Step 4: Make Holes in the Steel Fence

While drilling into steel may sound like a challenge any more but with correct type of drill bit this is not a big task at all.

  • Select the Right Drill Bit: Tapping is done using a drill that has a metal suitable bit. The best tools to use while working on steel is cobalt or titanium bits.

  • Drill Slowly: Press continuously and use slow speed when drilling. Steel is very hard metal they can break so it may lead to the bit getting very hot due to rushing. Reloading can be a good thing to do, especially when one has to pull the bit out and let it cool for some time.

  • Create Holes for Bolts or Screws: If you are using bolts then make sure the holes you are making is slightly larger than the bolts so that you can easily fix the bolts. When using screws, drill the holes just big enough to accept the thickness of the screw thread.

Step 5: Secure Mailbox Mounting Brackets

Once you’ve ensured your holes have been drilled it’s now time to fix the mailbox.

  • Position the Brackets: Put the mounting brackets on the locations of the holes which you have drilled.

  • Insert the Bolts or Screws: Now, tighten the bolts or the screws through the brackets into the fence with the use of the nuts. Some of them have square nuts which can be tightened by an adjustable wrench or by using a socket set.

  • Double Check Alignment: After tightening it to halfway, you should use your level to make sure the mailbox is aligned properly. Adjust as necessary.

Step 6: Secure the Mailbox

With the brackets installed, it is time for hanging the mailbox to the exterior wooden panel facing the road.

  • Place the Mailbox on the Brackets: Specifically, this step may differ depending on your mailbox model Although mailboxes can vary slightly in design, this step should be done in a specific manner. A lot of mailboxes are meant to be mounted on brackets you’ve installed previously.

  • Screw or Bolt the Mailbox to the Brackets: Install the four screws which come with your mailbox to the mounting brackets in order to fix the mailbox firmly. Make sure everything is well fixed but avoid over tightening since you many end up damaging the mailbox or the fence.

  • Test the Stability: Pull the mailbox a little to make sure it is well fixed on the panel and cannot shake.

Step 7: Weatherproof the Installation

Steel fences are exposed to the elements, and over time, the mounting points of your mailbox could rust. Here’s how to protect them:

  • Apply Rust-resistant Paint: Paint the drilled holes and any exposed metal with rust-resistant paint to prevent corrosion. This step is especially important if you live in a rainy or coastal area.

  • Inspect Regularly: Check the mailbox and its mounting hardware regularly for signs of rust or wear. Tighten any loose screws or bolts as needed.

Step 8: Finishing Touches

You’re almost done! Now it’s time to add any final touches to your mailbox installation.

  • House Numbers: Attach your house number to the mailbox or nearby on the fence to ensure the mail carrier can easily identify your address.

  • Mailbox Flag (Optional): If your mailbox has a flag to signal outgoing mail, ensure it is properly installed and functional.

  • Personalization: Some homeowners like to add decorative elements or nameplates to their mailbox. If this is your style, now’s the time to add a personal touch.

Troubleshooting Common Issues

Mailbox Shakes or Wobbles

One of the most common instabilities you may encounter is a mailbox that shakes or vibrates after being placed in place. This mostly comes about when the screws or bolts holding the joints are poorly tightened. In time the even such conditions as wind or rain may move the screws and thus destabilize the structure. 


To rectify this, start by ensuring that all the screws or bolts used in the course of installation are tightened properly. If any is loose, then use the wrench or screwdriver for turning them to be tighter. Take extra care not to over tighten the nut as this may ruin the threads, the mailbox or fence.

Drill Bit Overheating

Whenever the drilling process takes place through a piece of steel, there is usually a lot of friction which results to heat. If possible, avoid using a drill and instead use a sharp cutter since if the drill bit gets hot it will become blunt or may even snap and this will not make work easier. 


Overheating may also cause discrepancies of the holes whereby the drilled holes have sharp edges which may not easily allow for the correct fitting of the mailbox.


In other words, it is recommended to pause from drilling and take breaks often to avoid generating a huge amount of heat. Carry out drilling for a few minutes before letting the drill head to cool for the same time before continuing.

Fence Too Thin for Mounting

In some cases, one will discover that the steel fence is not very thick to actually be able to support the mailbox. Thin steel may be actually too weak in terms of thickness to let the screws or bolts grab it enough to prevent the mailbox from feeling flimsy and like it might fall off.
