    Castrads sand, grind and fettle all edges of their cast iron radiator sections to ensure they’re smooth and free from flashing. They use their own high-quality 2 pack primer which finishes and hardens. 


    Their Signature range of colors is cost-effective and designed to blend into most interiors. You can match your interior with selected Farrow & Ball® paints or choose from their Bare Metals collection for an unparalleled artisan finish.


    All finishes are covered by their ten-year Ironshield Guarantee
