Steps on Installing Metal Fence Posts

1. Dig a Hole

Dig a hole about 2 or 3 feet deep using an auger or a post hole digger. Fence posts are best set 2 or 3 feet deep on the ground to provide stability. As for the diameter of the hole, it should be three times the diameter of your posts, so a 2-inch diameter pole can be set in a 6-inch diameter hole.

2. Insert the Post

After digging the hole, insert the post and make sure it is level, and plumb on all sides. Use a level to ensure that your posts are not wobbly inside the hole.

What Are The Pros And Cons Of Using Metal Fence Posts

Now that we've talked about how you can set your metal fence posts with concrete, some of you might still be undecided if they are the best option for you. Here are some pros and cons of using metal fence posts.


One of the things that metal fence posts do better than most materials is their durability, especially against outdoor conditions. Since fences are placed outdoors, they are bound to face harsh elements and they are always battered by physical wear and tear.

Most metal fence posts are made of galvanized steel, making them very sturdy and resistant to rust. This makes them a better choice in places where the weather tends to be very harsh or if termites are abundant in the area.


Steel is generally very low maintenance because as long as it is securely fastened on the ground, you don't have to worry about them. Most metal fence posts are treated to last for a very long time, so if you're looking for a very low-maintenance to maintenance-free option, then this is the way to go.


Technically, steel fence posts are much more expensive than other materials. However, this cost compensates for the fact that they are very sturdy and they need very minimal maintenance.

Metal fence posts also last twice as long as other materials such as wood, so by the time you have to set up a brand new wooden fence, your metal posts are still standing strong.


Fences with metal posts often give that modern and industrial feel to any setting. However, one of the benefits of using metal fence posts is that you can literally use a lot of materials for the fencing itself. Metal fence posts can support wood, chain link, and most fencing materials available.

How Long Do Metal Fence Posts Last?

We all know that metal fence posts are durable, but how long do they exactly last? Do they really last longer than the commonly used wood posts? What makes these metal fence posts more durable than the others?

The answer lies in the kind of material that is typically used for fence posts. When you get posts installed, professionals use galvanized steel for fencing projects. This is because galvanized steel has a layer of zinc coating to it, protecting it from rust, acid, and erosion.

Metal fence posts made with galvanized steel can last for about 50 to 70 years with almost no maintenance. Steel is also virtually indestructible—this material is known to be fireproof and if secured properly and correctly, it can withstand winds of up to 110 mph.

Final Thoughts

Installing a permanent fence means getting to know how to keep it sturdy for many years. For metal posts, having your fences installed in concrete will ensure excellent durability. Don't forget to maintain those fences and your property will be well-protected for a very long time.
