Why Security Doors
Premium Security
Patented continuous hinged construction delivers superior strength and a cleaner appearance than traditional piano hinges — with no soot buildup over time.

Security doors with custom curves for 90°, 120°, 135°, and 150° angles — bent and heat treated in-house for the fastest delivery in the industry.
Up to 28 Feet
Curtains can span hundreds of feet wide and up to 28 feet tall. Counter height to full height openings with height-adjustable hardware available.
