Gemini Sign Corporation has been providing premium sign letters and quality signs to sign professionals and businesses for over 40 years. Our signs and letters are all of the highest quality craftsmanship and delivered with the impeccable reliability that clients have come to expect from us over time.

Gemini products are the best in the business and are produced by the world’s largest manufacturer of plastic and metal dimensional sign letters.  We carry plastic letters (injection molded plastic letters, formed plastic letters, and cut acrylic letters).  Fine ornate metal letters (both flat cut metal and cast metal) are available in a variety of styles and finishes such as aluminum, brass, bronze, copper, hot rolled steel, stainless steel, and baked enamel.   We are a leading supplier of changeable copy including gas pricing letters, snap-lok, and slotted letters.  Our craftsmen use the finest materials to produce other custom products such as high quality cast metal plaques and etched plaques that incorporate your own artwork.

In addition, should you ever have a problem with your order we will go out of our way to make it right. If a Gemini letter, logo, or plaque should ever break, crack, chip, fade or fail to look as good as the day it arrived, we will replace it under our Lifetime Guarantee. Our goal is to win your business, one order at a time.
