Powder-coated in any RAL colour

Dual-colour is a popular choice and reflects traditional frames where the outside is painted a different colour to the interior, allowing for greater flexibility in interior decorating.
Stock Standard colours are as follows:
Note: paint surcharge applies for non-standard RAL colour
