Powder Coating

Superior In-House Powdercoating Backed by Supacote including an Advanced 5-Stage Pre-Treatment process that Exceeds Industry Standards.

At Otter Fencing, we provide premium powdercoating services that meet and adhere to Australian Standards for durability, finish quality, and corrosion resistance. Through our affiliated company, Supacote, we manage the entire coating process in-house, giving us complete control over quality, turnaround times, and consistency. This integrated approach ensures that every product receives the highest level of care and attention.

Unlike many competitors, we use an advanced 5-stage pre-treatment system to prepare galvanized and raw metals for coating—significantly improving adhesion and long-term performance. This system ensures that our finishes stand up to the harshest conditions while maintaining their appearance and integrity.

Most fabricators and coaters skip or streamline these critical preparation steps—but at Otter Fencing and Supacote, we don’t cut corners. This is what gives our powdercoating a longer lifespan, better finish quality, and superior protection compared to standard offerings on the market.

Whether it’s fencing components, structural steel, or custom fabrications, our powdercoating process ensures your products look great and perform even better.
