Aluminum Sheet: 3003-H14 alloy (Standard) or 5005-H34 alloy (For use with anodized finishes). Typical minimum thickness 20 Ga. (.032” / 0.8 mm)
Stainless Steel Sheet: Type 304 (Standard) or 316 (For higher degree of corrosion resistance). Minimum gauge 22 Ga. (.031” / 0.8 mm)
Galvanized Steel Sheet: Galvanneal Satin Coat, Typical minimum 24 Ga.(.028” / 0.7 mm)
Aluminum: Baked polyester powder, or two or three coat fluoropolymer coatings by PPG® or Valspar®.
Class I or II anodic finishes.
Stainless Steel: Satin brush # 4, Mirror # 8 or other readily available finishes for example, Non-Directional Brush or Random Swirl.

Metal Wall Panels are typically supplied up to 3’-6” wide by up to 8’-0”.
Metal Walls are available both non-perforated (non-acoustic) and perforated (acoustic). Perforation patterns are limited only to the type of material and gauge chosen and available tooling. Presently Nelson offers more than fifty different perforation patterns ranging from diagonal (45-degree), staggered (60-degree) to straight as well as round, square and oblong holes. Our standard acoustical material consists of a Black pre-laminated fleece (SoundTex®) bonded to the concealed face of the wall panel plus a layer of minimum 1½” thick 1.5 lbs. density fiberglass insulation.

When durability, acoustics, or simply the beauty of metal is a major criterion for interior vertical surfaces, Nelson Architectural Metals Division has a solution. Available in a wide variety of designs and finishes, we manufacture metal wall panel systems for commercial, institutional and transportation facilities across North America.
Metal wall panels are available in a variety of metal alloys best suited for the intended application and typically range from .064 up to .125 inches in thickness. The most common panel alloys are 3003-H14 for aluminum and T-304 and T-316 for stainless steel. For optimal results, panels intended for anodizing plain (Mill) or brushed finishes generally require the use of a 5005-H34 alloy.
In addition to the aforementioned options, baked powder enamel, and two and three-coat fluoropolymer paints are commonly used to enhance the appearance of our panels. Nelson also offers a wide range of linear, non-directional and selective brushed finishes, particularly in stainless steel, as well as faux-wood options like our exclusive Ourborite™ finish.
Metal wall panels are available in non-perforated and perforated varieties. Non-perforated panels offer little in terms of acoustical properties other than reflecting sound where required. As a result they are generally used in instances where other features, for example ease of cleaning, are predominant factors. To achieve good acoustics, (High NRC or Noise Reduction Coefficient values) a perforated wall panel with an open area of 15 to 20 percent, together with an acoustical fleece (SoundTex®), should typically be used in combination with a fiberglass matt for optimum sound absorption. A wide variety of perforation patterns are available (straight, diagonal, staggered), as well as a range of hole sizes (round, square, oblong). The Nelson fabrication team works symbiotically with the architectural team's vision regarding decorative metal wall panels.
At Nelson Architectural Metals Division we draw from a resource base of over 150 highly skilled employees, many of whom have been engaged in this type of manufacture at Nelson for more than 25 years. Our ability to custom engineer and fabricate metal wall panel systems to meet the rigorous demands of architects and designers makes for a perfect fit from the conception to the completion of a new space.
