Grand Scale, Traditional Style

Hand Polished Cast Iron Radiators

Hand polishing cast iron radiators is a very time consuming process. Each section is individually polished with a series of bespoke polishing wheels.
We only polish the visible areas - the front, the top and on the end sections but not on the back which would be placed against the wall.
