Finishes and materials

Products in this collection are made from solid brass and are available in Antique Brass, Matt Bronze, Polished Brass, Polished Chrome, Polished Nickel, Satin Brass, Satin Chrome and Satin Nickel. Polished Nickel is an uncoated finish with a warm golden hue that will develop a gentle patina unless buffed regularly with a soft cloth. Matt Bronze is an aged finish that will lighten naturally on edges and frequently touched areas, revealing the brass beneath over time. Antique Brass has russet hues over a brass undertone for a warm, mature look that suits period homes. Always choose all your door furniture from the same brand and finish to guarantee an exact colour match.
