Polished Bronze sprung loaded letter plate

This Polished Bronze finish is manufactured from solid unlacquered bronze containing a minimum of 85% copper. This finish undergoes an accelerated ageing process and is then re-polished, leaving any decorative details dark and larger surface areas more polished. If the intention is to allow the surface to age, no attention needs to be given. Over time the bronze will acquire a darker and more aged patina. However, polishing with brasso will give the product a natural sheen where required. This finish has been salt tested to 480 hours, which meets grade 5 British Standard.
