Standard Doors

Standard doors are manufactured from stretcher level quality, cold rolled steel. The polystyrene core insures a continuous bond of metal skin to core. The polystyrene core also provides good sound deadening qualities and low thermal conductivity.

All standard doors are thoroughly cleaned and phosphatized to inhibit corrosion and increase paint adherence. A one coat primer provides further protection from corrosion and serves as an excellent base for field painting.

Standard Door Dimensions:

Width: 2' 0" through 4' 0"
Heights: 6' 8", 7' 0" and 8' 0"
Thickness: 1-3/8" and 1-3/4"
Door sizes are nominal. Doors have 1/8" clearance on top, lock edge and hinge edges. Standard door clearance for threshold is 3/4"

Standard doors are available in 1-3/8" [35mm] and 1-3/4" [45mm] thickness and constructed of 16 [1.3mm], 18 [1.0mm] and 20 [.08mm] gauge cold rolled steel or paint grip steel. Also available on a custom order basis are doors constructed of zinc-coated steel and stainless steel sheets.

Doors are available in all popular standard widths and 6'-8" [2032mm], 7'-0" [2134mm] and 8'-0" [2438mm] heights. Door hardware preparation includes 1-1/2 pair 4-1/2" [113mm] hinges on 6'-8" [2032mm] and 7'-0" [2134mm] doors, and 2 pair 4-1/2" [113mm] hinges on 8'-0" [2438mm] doors. Lock preparations include cylindrical government series 161 with 2-3/4" [70mm] backset, government series 86 mortise blank and rim and vertical rod exit device reinforcement.

All doors and frames meet or exceed specifications set forth by the Steel Door Institute.

Steel Door Construction

Standard doors are constructed of 16 [1.3mm], 18 [1.0mm] or 20 [.08mm] gauge cold-rolled stretcher level quality steel and are full flush construction 1-3/8" [35mm] or 1-3/4" [45mm] thick. Door skins are brake formed at the edges and spot welded to 16 [1.3mm] gauge perimeter channels.

7 [4.3mm] gauge combination standard / heavy weight hinge reinforcements are projection welded to a one piece, full height channel. Internal lock reinforcements are spot welded to the door. Doors have vertical seams on edges. Seamless doors (edges filled and ground) are also available.

The standard core is a polystyrene slab core. It is bonded under pressure to both door skins with a continuous coat of pressure sensitive adhesive. After doors are thoroughly cleaned and phosphatized to inhibit corrosion, doors receive one coat of primer. These doors have square edges and are non-handed. Handing is accomplished with hinge filler plates. Also available on custom orders are doors constructed of zinc-coated sheets and stainless steel sheets.

Hardware preparations for standard doors include:

Hinge preparations are for full mortise template hinges.

*4 1/2 [113mm] standard weight hinge reinforcements are easily modified to accept 4 1/2" [113mm] heavy weight hinges.
