Custom Bulletproof Structures & Shelters to Meet Any Industry's Needs

Since 1975, Keystone Structures has been manufacturing bulletproof buildings and structures  for a wide variety of applications throughout the United States.

Our preassembled structures are available in numerous styles and finishes and can be assembled with state-of-the-art plumbing and wiring technology.

Our designers will work from a customer’s drawings, create a prefab building to fit a site plan or pre-existing foundation, or draft a plan from a rough idea based on individual needs and specifications.

Our clients are situated in 49 states and include many leading industrial companies. Contact us today at 1-800-525-1567 for instant and superior customer service.
