Whether you’re concerned about durability, maintenance, cost-effectiveness, or customisation options, we’ll explore the advantages and drawbacks of powder coating, helping you determine if it’s the right fit for your steel post and rail fencing project. 


Understanding Powder Coating for Steel Post and Rail Fences. 

Powder coating is a method of applying a protective layer on top of steel posts and rail fencing and other substrate surfaces. Unlike paint, powder coating doesn’t contain solvents and is applied in solid form. It adheres through a heat-binding process. 


While both powder coating and paint offer protective coatings, powder coating is applied as a dry powder and cured with heat, resulting in a highly durable finish with excellent resistance to chipping and fading. Paint, on the other hand, is liquid-based and forms a protective film upon drying. 


Although paint provides colour and protection, it may be less resilient compared to powder coating. Due to its long-lasting properties, powder coating is often the preferred choice for protecting steel post and rail fences. 


Pros of Powder Coating for Steel Post and Rail Fences 

Enhanced Durability of Steel Post and Rail Fences 

Different types of powder coating offer varying levels of performance. Opting for a high-quality powder coat ensures better resistance to environmental conditions, like harsh sun, rain, mould and corrosion. In scenarios where animals may chew or rub against the fence, powder coating can withstand wear and tear more effectively than traditional paints. 


Even when applied to non-galvanised steel, powder coating provides a strong shield that is resistant to chipping, and cracking, and doesn’t let the protective layer be compromised. It offers superior protection against moisture and rust, ensuring the longevity of the fence. 


Long-lasting beauty of Steel Fences 

Powder coating ensures a longer lifespan for your fence, while also offering superior environmental durability. With this method, your fence maintains its beautiful appearance for a long period. By choosing a superior powder coating, you can confidently embrace the “do it once, do it right” approach, enjoying a visually appealing and resilient fence that withstands the elements. 


Easy maintenance of Steel Post and Rail Fences 

Opting for super-durable powder coating results in lower maintenance demands compared to painting or using inferior coating options. The high quality of powder coating makes maintenance tasks easier and less frequent. With its durable and long-lasting finish, your fence will require minimal upkeep, allowing you to enjoy its beauty without the hassle of regular maintenance. 



While powder coating may involve a higher initial cost, it proves to be a cost-effective choice in the long run. Despite the higher upfront investment, powder-coated fences save you time, money, and effort in terms of repairs and maintenance. The durability and longevity of powder coating surpass standard paints, reducing the need for frequent touch-ups or repainting. By choosing powder coating, you can enjoy a beautiful and resilient fence while minimising expenses over time. 


Customisation and Versatility 

Powder coating offers a wide range of colour options, allowing you to customise your steel fence according to your preferences. Most powder coaters provide the flexibility to choose from a vast array of colours, ensuring that your fence complements the aesthetic of your property. 


However, it’s essential to verify the colour options available with your specific powder coating system or supplier, as some suppliers may offer limited choices such as the Premium Steel Post and Rail fences from Stock & Noble are only available in textured black and gloss white.

Moreover, powder coating provides versatility in terms of finishes. You can achieve various finishes, ranging from high-gloss to matte, to suit your desired look. Consulting with your supplier will help you determine the type of finish that best matches your vision. 


While everyday paint suppliers may also offer colour and finish options, powder coating stands out for its ability to deliver a durable and long-lasting coating with an extensive range of customisation possibilities. 


Cons of Powder Coating for Steel Post and Rail Fences 


Difficulty in Repair and Touch-Up 

While powder coating is known for its durability, there are instances where the coating may get damaged, leading to challenges in restoring its original appearance. 


In the worst-case scenario, if the powder coating finish is damaged during transport or due to persistent chewing by animals, it becomes tough to bring it back to its former state. Repairing and touching up powder coating and achieving an original look is basically impossible without re-coating the entire piece. It will always be difficult to make touch up painting look good, eventually.  


Higher Initial Cost of Steel Post and Rail Fences 

As shared on earlier, compared to other coating options, powder coating typically involves a higher initial cost. This factor might pose a limitation for property owners with a limited budget. They may find it difficult to afford the premium price of powder-coated steel post and rail fencing. 


Limitations for Welding, Screwing, and Customisation 

When planning to install a fencing system that requires welding, screwing, or customisation during the installation process, powder coating may not be the most suitable choice. This is because any welding or penetration of the powder-coated finish can compromise the entire effectiveness of the coating. 


If the powder coating on the steel is breached due to welding or screwing, moisture can seep in and create a separation between the powder coating and the steel. This can lead to potential issues such as rusting and a compromised protective barrier. 


To mitigate these concerns, it is advisable to consider a system where all components are powder coated in the factory and installed without the need for screws or nails. For example, Buckley Steel Post and Rail fencing is an engineered fencing system that has pre-drilled holes and doesn’t require any screwing of nails during installation. Thus the steel remains safely packed inside the protective layers of powder coating and no need to penetrate the finished coating.  

However, in the case of pre-powder coated cattle rails like TopRail from Blue Dog Fences and Post and Rail from Dunn and Farrugia the use of screws during installation might breach the coating and compromise the steel fencing. 


Note: When installing Buckley fencing, in cases where cutting short rails is necessary, it is important to address the exposed areas of the steel. Applying a layer of cold-gal spray paint provides additional protection and prevent the onset of any rusting process. 


Is Powder Coating the Right Choice for my Steel Post and Rail Fences? 

You are considering a high-end Steel Post and Rail Fencing for your property and wanted to know further about the protection and value offered by powder coating. Is it worth investing or should you just use regular steel paint? 


Now you know when it comes to choosing the right coating for your steel post and rail fence, powder coating emerges as a highly favourable option. Its numerous benefits, including enhanced durability, long-lasting beauty, easy maintenance, and cost-effectiveness, make it an attractive choice. 


It’s also important to be aware of certain drawbacks associated with powder coating. Repairing and touching up the coating can be challenging. Additionally, the higher initial cost of powder coating may pose budget constraints for some individuals. 


In conclusion, when considering fencing systems for various applications worldwide, it is evident that most suppliers prefer powder coating whenever possible, particularly in modular systems like Buckley. This preference is driven by the desire to achieve a superior finish and ensure long-lasting durability. 


However, it’s worth noting that if a customer prefers a non-engineered system that allows for customisation and welding, high-quality paint can be a viable alternative to powder coating. Since the paint can be applied post installation and cover up any breaches in steel made during screwing up of fence together. 


Now that you’ve learnt the pros and cons of powder coating systems, the next step is to know the truth behind different types of powder coating and pre-treatments applied today. This knowledge will help you evaluate and choose the right steel post and rail fencing solution for your property.   


Ultimately, the choice between powder coating and alternative coatings depends on your specific needs and preferences. By carefully assessing the pros and cons, consulting with fencing experts, and considering factors such as budget, customisation requirements, and installation methods, you can make an informed decision that ensures a durable, visually appealing, and well-protected steel post and rail fence for your property.
