Natural Bronze numbers and letters are water-jet cut from flat sheets of bronze in the various thicknesses mentioned in the table above. The faces of these pieces are then brushed or polished. The returns are bead-lasted. For the final step, the pieces are clear-coated and baked with a glossy 2-part hardened acrylic polyurethane clear coat.
Our solid bronze numbers and letters are cut from lead and mercury-free alloy NAVY G 88-8-0-4 (nominal: Cu 88 Sn 8 Zn 4).
WARRANTY EXCEPTION: Brushed or Polished bronze address numbers are not warranted for high moisture areas, such as constant moisture from a garden sprinkler, or for salt-water, marine environments.
For a similar cut metal appearance that we will warrant in such salt-water environments, chose gold-anodized aluminum. If you prefer, we can clear-coat the gold-anodized aluminum so that it will have a glossy appearance similar to Brushed Bronze.Also consider our Stainless Steel for your beach addresses.
