Cast Plaque Surface Finishes
Once the background of the bronze plaque has been painted, the surface
areas(these are the raised letters of lines of artwork) are highlighted
by sanding (flat areas) or buffing (sculpted areas). To
inhibit natural oxidization, a clear, protective coating is then applied.
Satin Bronze The Natural metal color with subtle horizontal grain lines meets NAAMM finish designation M33-C11-060.
Polished Bronze The natural metal color buffed to a high gloss, obtained by polishing
with successively finer abrasives, then buffing with fine buffing
compound. Meets NAAMM finish designation M42-M22-C10-060.
Chrome Plated Bronze The raised surface of the bronze plaque is polished to meet the
polished bronze specifications. The background of the plaque remains
in its "natural sandblast" state, providing contrast with the polished
raised surface. The entire plaque is then electro-plated using a standard
commercial copper/nickel/chrome plating process.
In order to protect the natural, highlighted finish of a cast bronze
plaque, two options are available:
Clear Protective Lacquer Providing a low gloss appearance, this clear coating was developed
to help ensure many years of carefree maintenance.
should be selected when matching older plaques or when a lower gloss
look is desired (particularly for interior applications.)
Polyurethane Protective Coating A 2-part coating for protection in the harshest environments. This clear coat
can only be factory-applied and provides maximum protection. This
coating is applied with a heavier thickness than our clear protective
and is available in a high gloss version only. It is
particularly effective in harsh, exterior environments, where bronze
plaques are exposed to salt, pollution and weather.
maximum size available for polished bronze plaques is 48" x 36". A
polished finish is not recommended when there are large raised areas
due to normal
surface inconsistencies inherent in the casting process.
casting alloy of aluminum does not lend itself to polishing.
Polished aluminum plaques are not available.
- Polyurethane is our standard clear protective coating for outdoor plaques. Unless otherwise
specified, all plaques will receive this clear protective coating.
