About Invincible | A Legacy of Metal Fabrication Proven Through Furniture, Built for More
Invincible’s roots trace back to 1904, when the Invincible™ Electric Bank Protection Company was founded in Belle Plaine, Iowa. From the beginning, the company was built on precision metalworking—engineering and manufacturing products such as safes, vaults, and secure storage systems where strength, durability, and reliability were critical.
Today, more than 60% of Invincible’s business is contract manufacturing. While much of that work continues to support the furniture industry, our capabilities are not limited by it. The same processes that enable us to manufacture durable, high-quality furniture components are directly applicable to a wide range of industries requiring precision metal fabrication.
