Steel strainer posts are a popular choice for fencing due to their durability and strength. However, ensuring these posts are securely anchored in the ground is crucial to the stability of your fence. In this blog post, we will delve into the factors affecting the installation of steel strainer posts and provide valuable insights on how to hold them firmly in the ground.
The success of any steel strainer post installation starts with understanding the soil composition on your property. Begin by assessing the depth of water penetration in your soil. As a general rule, your post should be driven below the dry soil level, which is typically around 6 feet. This ensures that your post is anchored in a stable foundation.
Modern post drivers have made it easier to drive posts to considerable depths. When selecting the length of your steel strainer post, aim for a length equal to or greater than 2.4 metres. This ensures that the post reaches below the majority of soil water infiltration, providing a more secure foundation for your fence.
One common concern with steel strainer posts is the possibility of them being pulled out easily. Barbed posts offer a solution to this issue by providing resistance to jacking. Studies show that barbed posts have a resistance factor of 2.9, irrespective of the type of soil. This makes them a reliable choice for fencing installations.
To enhance the resistance of your steel strainer post, consider barbing it as shown here. This can be achieved by cutting an H shape at the base or by using specialised tools like Fenceline Solutions post grips. Barbing significantly increases the post's resistance to pulling forces, making it a robust choice for various fencing applications.
Ultimately, a well-driven, barbed steel strainer post of the appropriate length is a reliable solution for meeting a wide range of fencing demands. Proper installation techniques, combined with the inherent strength of steel, create a formidable barrier that can withstand the test of time and environmental conditions.
In conclusion, holding a steel strainer post securely in the ground requires careful consideration of soil composition, choosing the right post length, and enhancing resistance through barbing. By following these guidelines and leveraging modern post-driving technologies, you can ensure a sturdy and long-lasting fence that meets your specific fencing needs.
