Blast Door Construction
Formed, heavy gauge, steel face sheets constructed around a custom engineered, steel rib core with interior armor plate as required to protect against specified blast level.
Security and blast doors are available in flush design or with vision lights and as single or pairs of hinged doors, including single or bi-parting horizontal sliding doors. All assemblies are available manual or power operated.

Frame Configuration
Krieger offers standard frame designs and can engineer special frame profiles to complement wall construction and architectural style.

Standard and custom sizes available. No limits.
Tornado and Hurricane Doors
Krieger offers doors designed to meet the ICC 500 for tornado and hurricane safe rooms. The blast and pressure doors are designed to resist the wind speeds designated in ASCE 7 and the higher wind speeds designated in the ICC 500. The doors are also ADA Compliant. Our engineers can help you establish what door hardware is required and what hardware is permitted for safe rooms.
Note: FEMA does not certify products, but doors which have passed ICC 500 testing meet or exceed FEMA P-361 safe room criteria.
Swing door hardware includes modified builders' hardware or Krieger manufactured locks and hinges as required by blast rating.

Slide door hardware includes low friction trucks and rollers, low voltage control circuitry for electrical operators, and a variety of operator actuation devices.
Multi-point Lock
Doors can be fitted with a multi-point lock or SAT device and continuous hinging systems for added protection.
