Steel edge steel doors are designed with a full steel-edge perimeter creating a sturdier steel door. These doors are insulated with a polyurethane core and are available with a 90-minute fire rating when used with a 90-minute fire rated frame. Some people prefer the metal edge construction for extra strength and rigidity.
Therea are two versions of the steel edge fire doors. For commercial applications there is the Hollow Metal steel doors. For residential applications there is the RSP Series doors. All steel edge doors cannot have custom hinge and bore locations as the hinge, bore, and strike prep is completed by the factory and in accordance with fire safety codes.
RF Series Steel Edge Hinge Prep
The RSP or RF Series 90-minute fire door frames utilize a full size door (full in width and undersized in height by 3/4″ to accept a sweep). These frames are stocked by Reeb in 6/8, 7/0 and 8/0 heights and some have an option for 4” or 5-1/2” on center bore locations out of stock. When needed, these door can be trimmed by Reeb up to 3″ from the bottom only, dropping both hinge and bore locations by 3″.
