Doors are formed of two galvannealed or stainless steel sheets and are typically 1 3/4" thick, other thicknesses are available. |
|
Doors are internally reinforced with pairs of hat-shaped steel stiffeners. These stiffeners are joined together and run vertically (not more that 6 " apart) the full length of the door. The stiffeners are spot welded every 4" o.c. to both faces of the door and arc-welded to each other top and bottom. |
| Voids between stiffeners are filled with Polystyrene, Polyurethane or small celled Honeycomb core. |
| There are no seams on the faces or edges of the doors. Vertical edges of the doors are continuously seam-welded the full height of the door. |
| Exterior doors are capped to retard moisture from penetrating the door. |
| Hinge reinforcements are 3/16" thick. |
| All steel doors are internally reinforced at the top with a 12 gauge plate on both sides of the door.
This is for application of surface applied door closers and holders. |
| Glass window kit is of standard steel moulding with no exposed screws on the secure side of the door. |
| Louvers are standard design for required applications. |
|
Doors are chemically pre-treated and given one coat of rust inhibitive metal primer. |
