Florence sectional steel column radiators are our most versatile; they’re available up to 8′ tall and 6’6″ long and in five depth variants; from 2 to 6 columns.

Made to order in Italy and delivered in eight weeks for Signature finishes and twelve weeks for Bare Metal finishes. Steel multicolumn radiators are suitable for closed-loop hydronic systems but not steam or open-vented hydronic systems.


Florence radiators can be curved to fit into bay windows and around columns. Florence Curved is usually produced in two, three or four column variants.

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.
