TRELLIDOR COLOR OPTIONS

Trelli-Gates can be color coated to suit your style. Our security gates come in 2 standard gloss or matt colors (White and Bronze), and 6 non-standard colors (Sand, Beige Grey, Aluminum, Charcoal, Black and Stone Grey).

Special colors are available on request, allowing you to choose a color to best suit your decor or your corporate colors.

All Trellidor products are finished in a durable powder coating, as such the colors on this webpage will vary from the actual product color. This is due to the difference in the way that light reflects off different mediums. Should you have any concerns or would like to see the actual powder coated color, please speak to your Trellidor consultant who will be able to provide you with a physical sample.
