Armored door forced entry RC3 RC4 and fire rated EI30 for detention center and psychiatric hospital

SDx Toughshell

Armored door with forced entry resistance in level CR3-CR4 and fire rated EI30

Bünkl designs, manufactures, and supplies a complete range of high-security doors, certified from RC3 to RC4 (EN 1627-1630) for burglary resistance and EI30 (EN 1522) for fire protection. Our doors are specifically engineered for specialized healthcare facilities — such as psychiatric hospitals and rehab centers — and detention facilities, where heavy traffic of people and equipment (stretchers, wheelchairs, impacts from emergency openings, and other hazards) is part of daily operations.

Our “SDx Toughshell” range combines long-lasting durability with low-maintenance, hygienic materials and easy-to-clean finishes. These doors protect both staff and occupants, featuring specialized hardware for enhanced safety. Rounded cylinders and anti-suicide handles provide an extra layer of protection, helping prevent self-harm in environments where the risk of crisis or suicide is elevated.

Ideally designed for:

  • Pre-trial detention centers
  • Rehabilitation and detox centers
  • Psychiatric hospitals
  • Specialized healthcare facilities for challenging patients
