Stairwell Steel Door
Stairwell steel door
Stairwell steel doors serve the critical function of maintaining fire compartmentalisation between stairwells and occupied floor areas while providing secure emergency egress routes. Building codes mandate specific performance requirements for stairwell doors including fire resistance, self-closing operation, and appropriate hardware for emergency evacuation. The TORDRIX FlexCore Prime multipurpose metal door meets stairwell requirements with fire-rated configurations, self-closing mechanisms, and code-compliant hardware packages.
Engineered for performance. Designed for longevity.
