Anodized Aluminum Nameplate Materials and Options

metalphoto photo engraving durability drawingOur Metalphoto photo engraving process is recognized as the most durable of aluminum identification plate material by GPI, the National Association of Graphic and Product Identification Manufacturers, Inc. It is an ideal choice for those designing nameplates, front panels and tags that need to last. Our process performs and remains legible for decades in the harshest environments and most challenging applications. The material is durable and the graphics are high contrast with excellent resolution.

Material Characteristics

Namplate Graphic Imaging:

The images/graphics for your nameplate or panel are photographically imaged into the anodic layer of the aluminum giving you an image in black or gray-scale.

Thicknesses of Anodized Aluminum:

.003”(foil), .005”(foil), .008”, .012”, .020”, .032”, .063”, .090" and .125"

Anodized Aluminum Finishes:

  • Matte - non-reflective with dull finish
  • Satin - semi-gloss medium reflective material
  • #4 - brushed to resemble a stainless steel finish
  • Gloss - highly reflective, mirror-like
