ALUMINUM LETTER FINISHES

Satin Aluminum

The natural metal color with subtle horizontal or vertical grain lines meets NAAMM finish designation AA-M33-C11-R10.

Letters 3" in cap height and smaller have vertical grain lines.

Letters 4" and above have horizontal grain lines.

Letter returns (edges) are ground and sandblasted to a matte finish. Satin finish cast aluminum letters receive a clear protective low gloss lacquer.

Baked Enamel

Faces of letters are sanded to a smoother finish than for satin aluminum (equivalent to NAAMM finish designation AA-M32). The edges are ground and sandblasted to a matte finish.

The entire letter is then sprayed with an acrylic enamel color and baked to obtain a durable finish.

Colors available:

Satin Anodized Aluminum

The natural metal color with subtle horizontal or vertical grain lines meets NAAMM finish designation AA-M33-C11-R10.

Letters 3" in cap height and smaller have vertical grain lines.

Letters 4" and above have horizontal grain lines.

Letter returns (edges) are ground and sandblasted to a matte finish. Satin finish cast aluminum letters receive a clear protective low gloss lacquer.

Anodized Aluminum

The faces and edges of the letters are prepared the same as for satin aluminum. The entire letter is then clear anodized by immersing the letter in an acid solution and passing an electric current through the solution. The resultant surface coating increases the letter's resistance to corrosion and provides increased resistance to abrasion.

Not recommended for letters over 12" in height or 1" in depth.

Polished Aluminum

The faces of the letters are sanded with successively finer abrasives, then buffed to a bright polished surface essentially free of grit lines caused by preliminary operations. Meets NAAMM finish designation AA-M21-R10.

The edges are ground and sandblasted to a matte finish and the entire letter is sprayed with a clear protective low gloss lacquer.

This finish is available only on cast metal letters up to 2" high.

BRONZE LETTER FINISHES

Satin Bronze

The natural metal color with subtle horizontal or vertical grain lines meets NAAMM finish designation M33-C11-060.

Letters 3" in cap height and smaller have vertical grain lines.

Letters 4" and above have horizontal grain lines.

Letter returns (edges) are ground and sandblasted to a matte finish. Satin finish cast bronze letters receive a clear protective low gloss lacquer.

Oxidized Bronze

The faces and edges of these metal letters are prepared the same as for satin bronze. The letters are then dipped in an aqueous sulfide solution to achieve a golden brown statuary finish. Meets NAAMM finish designation M42-C55-060.

Variations in color from piece to piece can occur since this process depends largely upon chemical reactions. The patina will vary from a light golden hue to almost black. When ordering, specify Light, Medium or Dark Oxidized.

Polished Bronze

The natural metal color is achieved by polishing these metal letters with successively finer abrasives and then buffing to a bright polished surface essentially free of grit lines caused by preliminary operations. Meets NAAMM finish designation M22-C10-060.

Letter returns (edges) are ground and sandblasted to a matte finish. Polished finish cast bronze letters receive a clear protective low gloss lacquer.

This finish is not recommended on larger letters with large surface areas (wide letter strokes) due to normal surface inconsistencies inherent in the casting process.

Chrome Plated Bronze

The faces and edges of the metal letters are prepared the same as for polished bronze. Two layers of electro-deposited copper/nickel/chrome plating are then applied. Meets NAAMM finish designation M42-M22-C11.

Although environmental conditions can effect the metallic luster of these products, CU/NI/CR plating can withstand moderate atmospheric corrosion without deteriorating.

BRASS LETTER FINISHES

Satin Brass

The natural metal color with subtle horizontal or vertical grain lines meets NAAMM finish designation M33-C11-060.

Letters 3" in cap height and smaller have vertical grain lines.

Letters 4" and above have horizontal grain lines.

Letter returns (edges) are ground and sandblasted to a matte finish. Satin finish cast brass letters receive a clear protective low gloss lacquer.

Polished Brass

The natural metal color is achieved by polishing with successively finer abrasives and then buffing to a bright polished surface essentially free of grit lines caused by preliminary operations. Meets NAAMM finish designation M22-C10-060.

Letter returns (edges) are ground and sandblasted to a matte finish. Polished finish cast brass letters receive a clear protective low gloss lacquer.

This finish is not recommended on larger letters with large surface areas (wide letter strokes) due to normal surface inconsistencies inherent in the casting process.

Polished brass finishes are only available on letters up to 12" high.
