All Trellidor products are finished in a state-of-the-art powder coating plant, as such the colours on this page will vary from the actual product colour. This is due to the difference in the way that light reflects off different mediums.

Corrosion Resistant Coating 

The Trellidor powder coating system includes a pre-treatment process that enhances our products’ corrosion and UV resistance. The powder coating is ideal for coastal and inland conditions and increases the lifespan of the barrier by retaining its quality finish.
