Coatings & Surfacing
There are three basic categories for aluminum finishes
ANODIC FINISH, BAKED ENAMEL FINISH and POWDER COAT FINISH.
AluminumTube Railings by ATR Technologies, Inc. are available in a variety of finishes and colors. Each are available and are briefly described below:
This process creates a film of aluminum oxide on the surfaces of aluminum extrusions with a minimum coating thickness of 0.7 mil. This hard and durable finish resists abrasion and corrosion. It is especially well suited for heavy abuse environments. It is used for exterior and interior applications with a life expectancy of over 30 years depending on environmental conditions. Architectural Class I Anodize finishes are available in the following colors:
CLEAR (AA-M12 C22 A41)
GOLD (AA-M12 C22 A43)
LIGHT BRONZE (AA-M12 C22 A44)
MEDIUM BRONZE (AA-M12 C22 A44)
DARK BRONZE (AA-M12 C22 A44)
BLACK (AA-M12 C22 A44)
All Anodized finishes may be applied over pretreated aluminum extrusions. When used, the pretreatment number replaces the “M12” in the AA designation. The most commonly used pretreatments are: M32-Medium Directional Texture and M21- Smooth Polished.
GENERAL ANODIZE NOTES
Anodize is best used on 6063 or 6005 series aluminum alloys. Aluminum oxide coatings are known to have a hardness similar to that of a diamond. Since welding aluminum changes temper slightly, exposed welded joints may halo or appear slightly discolored under the anodized finish.
Baked Enamel Finishes
This coating process offers virtually unlimited colors and a wide variety of quality. Superior Performance: Kynar 500®, Hylar 5000®, Duranar®, or other baked enamel products that contain 70% polyvinylidene fluoride (PVDF) resin. These products meet the performance criteria of the AAMA 2605 specification. Such finishes have 30-year life expectancy on aluminum depending on environment.
GENERAL BAKED ENAMEL NOTES
Baked Enamels are factory-applied, oven-baked finishes that are available in virtually any color. Prices may vary depending on the color choice. Generally, colors are divided into standard, custom and exotic colors. Custom colors are available and priced accordingly. Exotic colors are generally considered bright, metallic or “XL” and therefore, may require a clear topcoat.Color matching is available. Color chips are prepared by the applicators laboratory for approval.
Powder Coat Finishes
This coating process offers hundreds of industry standardized “RAL” colors in many quality options: High Performance Powder: Tiger Drylac, Spraylat, Akzo Nobel and others provide a variety of powder coating options. High Performance Powder Coatings meet the performance criteria of the AAMA 2604 up to 2605 specification.
GENERAL POWDER COATING NOTES
Prices vary depending on the color selection. Generally, colors are divided into standard, custom and exotic colors. Many custom colors are matched first to the closest existing “RAL” color available. Feasibility to create custom and/or exotic colors is subject to the product manufacturer’s ability and priced accordingly. Color chips are provided from the applicator.
