Powder coated fencing is one of the most popular fencing coatings in Melbourne. You can see it across the city and regional Victoria, and that for a good reason. In the below post, we will focus on what powder coating is, some of the benefits of powder coated fences, and lastly, how to maintain powder coated fencing so it would stand sturdy for a long time.
Powder coated fencing is fencing that has been powder coated. Quite self-explanatory, really. Hence, let’s focus on what the powder coating process is. Note that other metal objects that can tolerate high heat levels of the curing process and can hold the electrostatic charge needed to affix the sprayed powder can also be powder coated, not only metal fencing. Additionally, this surface finishing process is suitable for non-metal substrates as well.
During the powder coating process, a dry, free-flowing, thermoplastic or thermoset powder material is applied to a surface, then melted and hardened to form an even coating. This process allows choosing from a wide range of colours, textures and finishes.
The powder coating process can be done using one of two main methods: electrostatic spray deposition (ESD) and fluidized bed application. The powder coating process is a multi-step process:
- Preparation stage
- Application stage
- Curing stage.
The equipment needed for the powder coating process includes, at a minimum, a spray gun, a spray booth and the curing oven. At the preparation stage, metal needs to be cleaned. Hence, wash stations, blast rooms, and dry-off ovens would be useful for a smooth operation.
Benefits of powder coated fencing
Compared to a conventional liquid coating method, powder coating has many benefits.
- Increased durability. It will last longer as it has a higher resistance to external impact, moisture and chemicals. Additionally, it offers better protection from scratches, abrasion, corrosion, fading, and general wear that happens over time.
- A wider variety of finishes, including colours and textures.
- Lower environmental impact as this coating type does not use/produce solvent and carbon dioxide emissions. Also, surface primers and disposal of hazardous waste during the painting process are not required. Thus, powder coating is recognised as a more environmentally-friendly alternative compared to liquid paint coatings.
- Faster painting process and turnaround time, as once the metal covered with powder coating is cooled, it can be immediately packed and shipped where needed.
- Lower material cost as overspray material can be recycled.
Maintenance of powder coated fences
Powder coating will protect your fencing from environmental factors. However, it also needs a bit of protection and maintenance itself.
- It is important to clean it regularly. Wiping your fence gently using a wet sponge will allow removing the dirt and debris that has accumulated there over time. Additionally, if some spots are hard to remove or salt has collected on top of your fencing, you can use a soft brush and a mild household detergent. That should get the job done. Note not to use detergents that contain solvents or petroleum-based chemicals as they could damage the powder coating. Lastly, rinse your fence with warm water. Then either let it dry naturally or use a cloth dry and polish the fencing.
- You are able to use a pressure wash on your powder coated fences. However, it tends to leave more residue behind.
- How often should you clean it? At least once or twice per year.
- If you notice any damage, such as rust or loose fencing post, it is a wise idea to fix it soonest as rust can spread and loose fencing posts can affect the stability of your metal fencing.
