Specifications
Part 1 | General
Specifications apply to the supply only of steel frame products including frames, transom frames, glazed or panelled, sidelite and window assemblies, fire labelled and non-labelled and steel doors, swing type, flush, glazed or louvered, fire labelled, with or without temperature rise ratings, and non-labelled as manufactured by Gensteel Doors.
Install fire labelled steel doors and frame products in accordance with NFPA-80, current edition, except where specified otherwise.
Method of measuring width of openings shall be measured from inside to inside of frame jamb rabbets. Height of openings shall be measured from the finished floor, exclusive of floor coverings, to the head rabbet of the frame. Doors shall be sized as to fit the above openings and allow a 1/8″ (3mm) maximum clearance at jambs and head of frame. A clearance of 3/4″ (19mm) maximum shall be allowed between the bottom of the door and the finished floor, exclusive of floor coverings. These are considered to be nominal clearances, subject to ordinary commercial variations.
Widths | Single doors 1′-0″ (300mm) up to 4′-0″ (1220mm) in 2″ (50mm) increments. Pair of doors 4′-0″ (1220mm) up to 8′-0″ (2440mm) in 4″ (100mm) increments |
Heights | 6′-8″ (2032mm) to 10′-0″ (3050mm) in 2″ (50mm) increments |
Door Thickness | 1 3/4″ (45mm) |
Submit shop drawings indicating each type of door, frame, steel, core and material thickness, mortises, reinforcements, anchorages, locations of exposed fasteners, openings (glazed, panelled or louvered) and arrangement of standard hardware. Include schedule identifying each unit, with door marks and numbers relating to numbering on drawings and door schedule of architect.
Materials and workmanship shall be warranted by manufacturer for a period of two years. The warranty is based upon the product being used with the hardware for which it was prepared, the assumption that normal industry and installation and usage recommendations were employed, that the product was properly painted and maintained, and was subject to normal use. The warranty is limited to the replacement or repair of said door or frame.

2.2 Fabrication | Frame Products
Exterior frames shall be [12] [14] [16] [18] gauge [welded] [knocked-down] type construction [thermally broken]. Interior frames shall be [16] [18] [20] [22] gauge [welded] [knocked-down] [slip-on] type construction. Frames shall be blanked, reinforced, drilled and tapped for mortised, templated hardware. Mortised cutouts shall be protected with steel guard boxes (may be omitted on drywall applications). Frames shall be reinforced, where required, for surface mounted hardware. Drilling and tapping for surface mounted hardware is by others, on site, at time of installation. show more
Frame product shall be either accurately mitred or mechanically jointed, securely welded on the inside of the profile. Butt joints of mullions, transom bars, centre rails and sills shall be coped accurately and securely welded. Welding shall conform to CSA W59-1984. Welded joints shall be ground to a smooth, uniform finish. Floor anchors shall be securely attached to the inside of each jamb profile. Weld in two (2) temporary jamb spreaders per frame to maintain proper alignment during shipment. show more
Knocked-down type frames shall be shipped unassembled. Frames shall have mechanical joints which inter-lock securely and provide functionally satisfactory performance when assembled and installed in accordance with ANSI/NFPA-80 Standards and the manufacturers’ Installation Manual. Floor anchors shall be securely attached to the inside of each jamb profile.
Slip-on type frames shall be shipped unassembled. Frames shall have mechanical joints which inter-lock securely and provide functionally satisfactory performance when installed in accordance with ANSI/NFPA-80 Standards and the manufacturer’s Installation Manual. Slip-on frames shall be provided with manufacturers’ proprietary design of wall anchorage comprising single, adjustable tension type per jamb and provision for secure attachment of each jamb base to stud runners.
