The Rule for Choosing the Height of Brace Arms

Hello everyone, I'm Marco from Fenceshop. Today we will answer a very common question: how to choose the height of diagonal brace arms based on the height of the mesh? First of all, the right question is: how to choose the height of the brace arms based on where they will be installed, rather than on the height of the mesh? Let's explore the "plus 25" or the "equal" rule together.

Introduction to Brace Arms

Brace arms are those angular supports that reinforce the starting or corner posts, essential for counteracting the tension of the wires and mesh. Understanding how many brace arms are needed has already been covered in other videos, but today we will focus on the height, which can be more complicated to determine compared to the posts.

The Heights of Meshes and Brace Arms

The heights of meshes available in the market range from 60 cm to 300 cm. The available brace arms, on the other hand, are only six. This means we need to find alternative solutions for very low or very high meshes. The primary mesh heights used are 100 cm, 125 cm, 150 cm, 175 cm, and 200 cm.

The Heights Table

We use a colored table with three columns (red, green, and blue) to determine the height of the brace arms. The green column represents the height of the mesh. Let's take an example: if we have a 150 cm high mesh, in the red column (for brace arms on the ground) we add 25 cm, so we choose a 175 cm brace arm. In the blue column (for brace arms on a wall), the height of the brace arm will be the same as the mesh, thus 150 cm.

Handling Non-Standard Heights

For non-standard mesh heights, such as 80 cm or 250-300 cm, there are no corresponding brace arms. In these cases, we must adapt the available brace arms, for example by cutting them or tilting more those of 125 cm. For very high meshes, like those in sports facilities, custom-made tube or boxed brace arms are used.

Correct Positioning of Brace Arms

Another important aspect is the correct positioning of the brace arms. They must be bolted to the second hole of the post, which is about 30 cm from the top of the post. This ensures a correct and stable positioning of the brace arm.

In conclusion, the "plus 25" rule for brace arms on the ground and the "equal" rule for brace arms on walls are easy to follow and ensure a correct and stable installation of meshes.
