Florence sectional steel column radiators are our most versatile; they’re available up to 8′ tall and 6’6″ long with no on-site assembly. They’re lighter than their cast iron cousins and have laser-welded joins, which means they can be curved to fit radial walls.

All models are available up to six feet six inches (40 sections) in length. Steel column radiators are always delivered fully assembled and ready to install.
It’s possible to make Florence radiators curved to fit into bay windows and around columns. Florence Curved is usually produced in two, three or four column variants and can be made in all heights up to 48 inches with welded feet as standard.
To ensure the correct fit, we’ll need to know two crucial dimensions: the chord, or width, and the camber, or depth, of the curve. When you’re ready to begin ordering we’ll provide detailed guidance on precise sizing.
