Deansteel 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. Deansteel 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.
