Material & Finish – Designed to Last, Built to Blend 

Material: Made from mild steel, selected for its strength, slim profile, and longevity – unlike bulky timber or modern plastic alternatives 

Finish: Factory-finished in a durable matt black polyester powder-coated paint (RAL 9005) – chosen to closely match traditional cast iron
