Use this CSI 3 part SimpleSpecs™ master specification to specify hollow metal doors and frames fabricated from cold-rolled steel, galvanized steel, or aluminum-zinc alloy coated steel sheet.
Glazed exterior hollow metal frames can be a source of water infiltration since they do not incorporate a weep drainage system.
Interior hollow metal doors are commonly specified with honeycomb cores in lieu of vertical steel stiffeners; the faces are flatter since no welds are used to secure the core to the faces.
Special fire-rated cores are required on fire-rated doors with higher fire ratings. Fire-rated doors and frames must conform to the listing to which they were tested. In general, doors must be self-closing and require smoke seals.
Hollow metal doors and frames are typically shop primed and field painted.
