Natural Brass architectural numbers and letters are water-jet cut from flat sheets of brass 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 "brass" alloy is, depending on availability, either C46400 Naval Brass (60% copper, 39.25% zinc and .75% tin) or a Muntz alloy C280 (60% copper & 40% zinc). Neither alloy contains lead. 60-75% of our pieces consist of recycled Navy Brass. All internal scraps are recycled.
Polished Brass requires (for polishing) that the piece have either welded or traditional studs. Our polished pieces in 1/8" stock are priced with welded studs. NOTE: Our polished finish is only available for numbers or letters 2" high or greater.
WARRANTY EXCEPTION: Brushed or Polished Brass 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.
