Finishes

General
Specifications for the surface finish of cast letters are identical for waterjet-cut letters. The letter returns (edges) for cast letters are ground and sandblasted. The edges for waterjet-cut letters have a fine matte finish.

Clear Coatings
Protective clear coatings are used on all metals except for stainless steel and Alloy 2024 polished aluminum. Coatings are available in gloss or semi-gloss.

Specify Interior or exterior installation. Coatings for exterior installation are polyurethane-based.

Light Oxidized Bronze

Medium Oxidized Bronze

Medium Oxidized Muntz Metal

Stainless Steel Finishes

Satin Stainless Steel

Satin

Random Orbital Stainless Steel

Random-Orbital
The natural metal color with multi-directional brushed lines, achieved with a random-orbital sander. Meets NAAMM finish designation M35-M4x-C10-060.

Aluminum Finishes

Satin Aluminum

Random-Orbital
The natural metal color with multi-directional brushed lines, achieved with a random-orbital sander. Meets NAAMM finish designation M35-M4x-C10-060.

Polished Aluminum

Polished
Faces of letters are sanded with successively finer abrasives, and then buffed to a bright polished surface essentially free of grit lines caused by preliminary operations. Meets NAAMM finish designation AA-M42-M21-R10.

Random-Orbital
The natural metal color with multi-directional brushed lines, achieved with a random-orbital sander. Meets NAAMM finish designation
M35-M4x-C10-060.

Color Anodic
Faces of letters are prepared the same as for satin aluminum. The integral color anodic is achieved using an acid electrolytic process. Available colors are Black, Light Bronze, Medium Bronze and Dark Bronze. Meets NAAMM finish designation
AA-M42-M33-C11-A34.

Duranodic 311 Light Bronze

Duranodic 312 Medium Bronze

Duranodic 313 Dark Bronze

Satin Anodized
Faces of 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. Meets NAAMM finish designation AA-M42-M33-C11-A31.

Polyurethane Painted
Faces of waterjet-cut letters are sanded to a smoother finish than for satin aluminum. The entire letter is then sprayed with a two-part acrylic polyurethane paint and cured.
