Standard RAL Colours 

All of our steel windows which we produce are hot dipped galvanised in compliance to BS 729 part 1 and this is to prevent deterioration to the steel frames and are then coated with a high quality polyester powder coated finish. 


Powder coating is a widely used finish seen throughout many different industries within the country and is a highly durable finish which is baked on to the surface of the galvanised steel to give a long lasting paint finish.


Here at The Cotswold Casement Company we have many different standard RAL colours which can be viewed from the .PDF below. We also can supply non standard colours from the RAL and BS colour charts if the customer requires. 

We can also offer a dual colour finish where the windows are powder coated externally and a wet sprayed finish internally using two different RAL colours.
