Polyester Powder Coating and Colours

AG210 windows and door frames are polyester powder coated: during this process the paint is baked on at high temperature providing a highly durable low maintenance finish.

Frames can be coated in any standard RAL classic colour: in a choice of finishes including matt, semi-gloss, gloss and hammerite finish allowing you to create bespoke windows for your home.

Dual colour – where frames are painted one colour inside and a different outside is available on request.

To provide a classic finish to the AG210, the following colours prove timeless,
RAL 9010 white
RAL 9005 black
RAL 9001 cream
RAL 1013 oyster white
A contemporary look is achieved using the popular RAL 7016 – Anthracite Grey and RAL 7012 – Basalt Grey.
