Signature Collection

Our core range of popular neutrals and monochrome finishes, developed especially for cast iron.

We have refined our painting process over the years ensuring the finish is hard-wearing and stays looking great.

Each radiator is dip primed and cured with infra-red, then dipped and cured again. After priming, radiators get two coats of hard-wearing two-pack paint, again with infra-red curing in between.

Black Iron

Black Iron is a new addition to the Signature collection. Here we use an acid-etch primer and three coats of two-pack lacquer to produce a smokey black whilst preserving the natural texture of the cast iron surface beneath.

Bare Metal Collection

Brilliant, lustrous finishes produced by hand using lacquers and specialist polishing techniques.

For the lacquered finishes we begin by tumbling the cast iron sections for 10 hours in a giant drum filled with ceramic pebbles. The sections are then tumbled for a further 8 hours with small porcelain beads and water. Powdered porcelain from the beads makes a paste with the water which gives a high shine to the surface of the iron.
We then use layers of primer and tinted lacquers to create deep colours that allow the lustre of the metal to show through.

Hand polished

For the polished finishes as well as Natural Brass and Aged Gold, the process is entirely manual. Each section is carefully polished against a spinning wheel through 12 grades of increasingly fine abrasive to achieve the various effects. They are then lacquered to complete the finish.
