Our Polished Chrome products are made from a base of solid brass coated with a durable chrome plating to give an exceedingly high-sheen finish. Favoured for its bright, bold appearance, Polished Chrome is well suited to contemporary designs and offers a smooth, mirror finish when polished. This works best if a cool, clean look is desired.
