Shaping The Mold: Gemini Cast Metal Letters And Logos

An Overview of Gemini Cast Metal Products

Since the mid-1980s, Gemini has been a leading producer of hand-finished cast metal letters and logos. Cast metal signage furthers a brand and company look by its timeless, lasting appearance.

Cast Metal Made By Skilled Tradesmen

What is cast metal? Cast metal is manufactured in a metal foundry that produces metal castings by pouring molten metal into a standard or custom mold to create a desired letter or logo in several depths and textures. Forging cast metal involves a thorough manufacturing process and a team of dedicated tradesmen to create hand-finished cast metal products. Our metal foundries run on all-electric, pollution-free furnaces and use Earth-friendly alloys free of lead and mercury. Cast metal delivers a distinguished, traditional appearance for your sign or message.

Perpetual Impressions

Cast metal is often made for building facades but can be great for indoor applications. Outdoor signage serves as an extension of a brand and cast metal signage instills the importance of services and offerings through its classic, defined look. Churches, universities, public safety organizations, and financial services are examples of where you would see cast metal signage.
