The GenShield Series is a temperature rise door designed to impede and limit heat transmission generated from a fire. The core’s excellent heat retardant characteristic protects the unexposed area thus allowing ample time for safe evacuation. In accordance to temperature rise standards, the unexposed door surface will reach a maximum of 250°F during the first 30 minutes of a fire and 450°F after 60 minutes. Standard doors are 1¾ in. (45 mm) thick and are available in 16, 18, and 20 gauge galvannealed steel.


  • Door faces are flush and free of any joints, welds or seams.
  • Longitudinal door edges are interlocked with mechanical seam and reinforced with epoxy adhesive (seamless edge optional).
  • Door edges are beveled 1/8” (3 mm) in 2” (50 mm).
  • Door hinge reinforcements are prepared for standard weight 4 1/2″ x 4 1/2” (114 mm x 114 mm) hinges which can easily be converted to accommodate heavy weight hinges.
