Security Doors
Engineered Protection with Architectural Elegance
Minimal Frame Projects offers a premium range of security doors that combine high-performance protection with sleek, modern design. Whether safeguarding residential properties, commercial buildings, or high-security facilities, our solutions deliver certified resistance against forced entry, ballistic threats, explosions, fire, and smoke — without compromising on aesthetics.
From aluminium doors with slim sightlines and bullet resistance, to robust steel systems tested to RC6 and FB7-NS, each door is engineered for specific threats and seamlessly integrates with surrounding architecture. Options include panic hardware, electronic access control, fire ratings, and anti-suicide features for custodial environments.
All systems are fully tested to European standards (DIN EN), and can be tailored with bespoke finishes, automation, and multi-threat configurations — ensuring your entrance is not only secure, but refined.
