Gemini’s etched plaques are the go-to choice for plaques that require precise detail for fine text, images or other intricate custom artwork. Chemical etching allows us to transfer virtually any design onto brass, bronze, copper or stainless steel. Etched plaques are a lower-cost alternative to cast plaques, while still delivering a high-end look.
Gemini offers four gauges of metal for your etched plaque: 1/16”, 1/8”, 3/16” and 1/4”. Artwork can be either raised or recessed, and backgrounds can be painted any single color or combination of colors. (Available standard painted colors are the same as for cast plaques, which can be viewed here.)
Brushed finish is standard, but polished finish is available on recessed copy plaques. There is also the option for beveled edges for gauges 1/8” and up. Maximum dimensions vary by material.
All materials for etched plaques are available in 1/16”, 1/8”, 3/16” and 1/4” gauges. (Metal Image is available in stainless steel only.)
Alloy C304 (Optional Alloy 316 also available)
Naval Brass Alloy C46400 – 60% Copper, 39.25% Zinc, 0.75% Tin (Muntz also available)
All etched plaques 1/4” thick are drilled and tapped.
Blind Mount (Stud Boss)
Plaques thinner than 1/4” can be stud mounted with welded stud bosses.
Double Face Tape
Strips of very high bond tape are applied to the back of the plaque.
Through-hole Mount (Screw Mount)
Holes are drilled through the surface of the plaque. Specify screw size and if the holes should be countersunk. (Plaques 1/16” thick cannot be countersunk and will include round head screws.)
For smaller plaques (up to 24” x 36”), Gemini offers a machine-etching process called Metal Image. Although only available in stainless steel, Metal Image offers several advantages:
- Greater detail than chemical etching
- Porcelainized stainless steel is impervious to nearly all conditions
- Less expensive than etching
