T-Posts for Fences: Which Section to Choose

There are many types of fence posts and I believe we all know them. However, not everyone knows which section to choose based on the height. In this video, we help you make the best choice. To be clearer, we will show you two tables that group the main sections of posts from two families of posts. I have to say that I took this table from the website of a well-known Italian producer of T-posts. I apologize to Filippo for taking it, but it's to help users better understand what we're talking about.

The Three Main Families of T-Posts

T-posts are divided into three main families:

  • Lightweight version
  • Standard version
  • Posts with larger sections

We will focus on the two most common families of T-posts. Let's start with the table of the standard line. These are the posts that fall in the middle of the three families and on which we focus the most.

Sections and Heights of the Posts

The heights 1 meter, 1.25, 1.50, 1.75, 2 meters, and 2.33 meters are offered with sections of 30x30x3.5 mm. However, for heights of 2 meters and 2.33 meters, we recommend using sections of 35x35x4 mm. For a height of 2.50 meters, the recommended section is always 35x35x4 mm. For a height of 3 meters, there is a 35x35x4 mm section, but we prefer a section of 40x40x4 mm.

In summary, companies offer T-section posts of 30x30x3.5 mm up to a height of 2.20 meters or 2.25 meters. From then on, it moves to a section of 35x35x4 mm. These traditional sections are perfect for supporting a mesh fence.

First Price Line

If we look at the table of the first price line, we see a range of lighter posts. What does lighter mean? It means they cost less. The sections remain 30x30x3.5 mm up to a height of 2.50 meters. For heights of 2.25 and 2.50 meters, sections of 35x35x3 mm with a thickness of 3.5 mm are proposed. The difference compared to other posts is the thickness, which goes from 3.5 mm to 4 mm, resulting in a lower weight and hence a lower cost.

Not surprisingly, we have also included a column of theoretical weight in kg in the tables. There is a significant difference between one post and another at the same height. The lighter version is ideal for those looking for something more economical but less performing.

Final Tips

In summary, here are the best sections based on height that we at Fenceshop recommend:

  • Heights of 1 meter, 1.25 meters, 1.50 meters, and 1.75 meters: T-section 30x30x3.5 mm
  • Heights of 2 meters, 2.25 meters, 2.30 meters, and 2.50 meters: T-section 35x35x4 mm
  • Heights over 2.50 meters: T-section 40x40x4 mm

If you look at the manufacturers' websites, you will find notes that discourage the use of the economical or standard version for the use of shade cloths. This is because the posts are not suitable for supporting certain forces. They are fine for holding mesh, but not for supporting a tarp or a fence with vegetation like ivy. We have already made videos on the sail effect on fences, which you can find in our links in the description. This does not mean that you cannot put up shade cloths, but that you need to evaluate if the post has the right section to support them.
