Armed with this information, you will be well-equipped to make informed purchase decisions and effectively resolve any issues that may arise promptly. We aim to empower you with the understanding and solutions necessary for a successful fencing project. 


Plastic Fence Posts Problem 1: Structural Weakness 

Plastic posts are generally softer compared to timber or steel posts. As a result, they will not perform well when used for structural purposes such as end or corner assemblies or gate posts. They don’t withstand pressure effectively. 



To address this issue, consider using steel end assemblies and gate posts, while utilizing plastic posts as intermediate posts. This way, the stronger steel or timber components will provide the necessary support for critical areas. 


Plastic Fence Posts Problem 2: Limited Fixing Capacity 

Attaching items that will come under pressure, such as horserail attaching buckles, to plastic posts can be problematic. Plastic posts are not suitable for securely fastening this type of fitting. 



Opt for steel or timber posts when you need to attach buckles or other heavy items securely. These materials provide better stability and support for such attachments. 


Plastic Fence Posts Problem 3: Crushing Effect 

Due to their hollow construction, plastic posts may experience a crushing effect when a bolt is tightened through the post to hold something on the front. This can lead to loose or sagging rails over time. 



 To mitigate this issue, consider using a spacer on the inside of the fence post to prevent crushing. However, it is crucial to ensure that the post is suitable for the specific fencing type before using this solution. Consult your supplier for guidance.

Plastic Fence Posts Problem 4: Sun-Induced Bending 

One significant issue with plastic fence posts is their tendency to lean or bend when subjected to sunlight, also known as the sunflower effect. The degree of bending experienced by these posts is influenced by the specific type of plastic utilized in their construction. 



Conduct thorough research and inquire about the measures taken by different manufacturers to address the impact of the sun. Hogan posts, for example, are designed and manufactured to minimize bending. Seek guidance from your supplier to ensure you choose the right post for your needs. 


Plastic Fence Posts Problem 5: Vulnerability to Breakage 

Plastic posts are more prone to breaking when subjected to forceful impacts, such as from vehicles or forklifts. They are generally less sturdy compared to timber or steel posts. 



Exercise caution when unloading and handling plastic posts, particularly during transportation and setup. While no significant issues have been reported regarding animal interaction, it is still essential to handle the posts with care. 


Plastic Fence Posts Problem 6: Pre-Drilling Requirement 

Unlike steel or timber posts, plastic posts often require pre-drilling before installation. This can add extra time and effort to the installation process. 



To expedite the installation, drill an undersized hole and then ram the post into the loosened soil. This method allows for easier and quicker post-installation. 


Plastic Fence PostsProblem 7: Limited Colour Options 

Most plastic posts are stocked in a limited range of colours. For example, Hogan posts are primarily available in black. 



 If you desire a specific colour, plan ahead and order custom-made posts in the colour of your choice. Some suppliers may offer other colours upon request, although they may need to be ordered in advance. 


Plastic Fence Posts Problem 8: Initial Cost 

Plastic posts are generally more expensive initially compared to treated pine posts. However, they offer long-term benefits such as termite resistance and reduced maintenance requirements. 



While plastic posts may have a higher upfront cost, they are easy to maintain and do not require frequent replacements. Over time, they can be a cost-effective choice due to their longevity and reduced maintenance expenses. 


Plastic fence posts have their advantages and disadvantages, and it is crucial to consider these factors when making a decision. By understanding the challenges associated with plastic posts and exploring the available solutions, you can make an informed choice that best suits your fencing needs.
