Wondering How To Install Steel Fence Posts?

It’s time to consider wood fencing a thing of the past. Prone to rotting, degradation and even falling apart under strong weather conditions, steel fence posts are the way to go for maximum durability, longevity and appearance. Not only do they look better, steel fences generally come a bit cheaper because the wood does not have to be regularly treated. They come in a variety of different types to suit your home’s appearance.

If you’re planning to build a steel fence around your garden, the most practical option would be a thinner gauge style post. The lighter material means it’s lighter on the wallet, is fairly easy to install and equally easy to replace. If you’ll need something stronger that can deflect water, it’s best to look into a galvanized steel fence, which will underground go a chemical process to keep the material from eroding. The shiny finish can also be quite attractive.

The first step is determining how large of an area you’ll be enclosing. If you’re building a fence to keep your pet enclosed in the background, you’ll want a fairly substantial area for them roam, as well as some access to some trees or shade. If the steel fence is meant to be closer to home for privacy or security reasons, it won’t have to be as expansive, but longer.

How much fencing material will I need?

To calculate how much material you will need, first determine the total fence length by the rail length, and also factor in the posts. Each fencing section will require two posts, three fence panels and two rails. This will create a 25-metre long boundary fence which will include more than 10 sections, requiring 22 posts, 32 panels and 22 rails. The total estimated cost is about $950.

For the posts, you’ll need to set them in place with concrete. Buy 20 kilogram bags of premixed concrete for this purpose. They usually cost about $7 to $10. Alternatively, you can create your own by mixing gravel, sand and cement in a 4:2:1 ratio.

Once you’ve purchased your posts, panels and rails, it’s time to map the location of where the posts will go. Using a measuring tape, determine where each post will go. Start from where you want the fence to finish and measure your posts in equal distances to determine the final length. Mark these distances, and be sure to remove any debris, rocks, obstacles or other obstructions for the work.

But wait!

Before you start digging away, speak with your local council to see if any building permits need to be acquired. They can also let you know if there are any height restrictions. A simple fence wouldn’t usually require a building permit, but it doesn’t hurt to ask. Also, let your neighbour know the fence will be going up, as they may have to share the cost of a future dividing fence.

Now it’s time to put up the fence posts.

1. Now that your area is clear, pick out the holes you’ll be placing your posts along the fence line with spray paint or small pegs. It’s easiest to do with a post-hole digger rather than an actual shovel. Each hole should be at least two feet deep so the fence post can be wedged in properly. Use metal stakes as temporary placeholders for the steel fence posts.
2. With your dry cement, slowly fill in the holes while leaving about one-third of a gap at the top. Once they’re full, insert the steel fence posts firmly and deeply in the ground. Use a leveling tool to make sure each post is level.
3. Now it’s time to fill the holes with the remaining cement, mixing it into the final third of the hole. Make sure you let the posts stands until they dry completely, unless you want to risk an unstable fence!

Now that your steel fence posts are installed, you can consider timber, brick, or other high-end materials to complete your fence. No matter what you decide, remember your steel fence posts needs to be retained. Use a broom to clean it occasionally of cobwebs and dirt, and keep soil away from the base rails. This will help avoid water retention, which reduces corrosion and damage.
