Substitutions: Not permitted.

2.2 STAINLESS STEEL DOORS

Provide 1 3/4" nominal thickness stainless steel doors as listed in the door schedule and indicated on the Drawings in accordance with this specification. Opening sizes, configurations and types shall be as indicated on the Drawings and/or door schedule.

Steel for door faces shall comply with ASTM A 666 specifier select (type 304) (type 316).

Finish shall be specifier select (# 4 grained) (# 2B mill finish).

Specifier: select or delete: Grain for # 4 finish shall run vertically.

Door faces shall be fabricated from specifier select (18), (16), (14), (12), (10) gage material.

Internal reinforcing members shall be fabricated from specifier select (hot-rolled or cold-rolled steel), (stainless steel type 304), (stainless steel type 316).

Fabricate faces and edges as seamless doors from two sheets of steel with no visible seams on either face or vertical edges; continuously weld door edges. Where finish is # 4, refinish edge welds to match grain.

All doors shall be handed with either square or bevel edges (at manufacturer's option).

Vertical edges shall be reinforced with continuous channels at hinge and lock edges. Channel shall be formed from one member; spliced channels are not permitted.

Hardware reinforcing shall be securely welded to edge channels.

Where welds would be exposed thus compromising the finish, a proprietary structural epoxy adhesive may be used (at manufacturer's option). Such connections shall demonstrate equality with a spotweld of similar size.

Door internal construction shall be specifier select (expanded polystyrene of 1.0 pcf nominal density) (impregnated honeycomb of no greater than 1.25" cell size) (polyurethane slab of no less than 1.0 pcf nominal density) (vertical steel stiffeners of no less than 22 gage). Fire protection rated doors shall be honeycomb core to comply with testing.

Hardware Preparation: Mortise, reinforce, drill, and tap to receive templated mortise hardware; reinforce for specified surface hardware in accordance with HMMA 861 and HMMA 866.

2.3 STAINLESS STEEL FRAMES

Provide stainless steel frames for doors or borrowed lights as listed in the door schedule and indicated on the Drawings in accordance with this specification. Opening sizes, profiles, anchors, and types shall be as indicated on the Drawings.

Frames shall be fabricated from specifier select (18), (16), (14), (12), (10) gage material.

Fabricate frames with tightly fitting mitered corners and butted stops. Tabs and slots at headers and jambs may be incorporated for factory alignment of assembly.

Frame corners shall be specifier select (knocked-down for field assembly), (welded continuously at faces), (slip-on drywall).

At welded frames where finish is #4, refinish miter welds to match grain.

Internal reinforcing members and anchors shall be fabricated from specifier select (hot-rolled or cold-rolled steel), (stainless steel type 304), (stainless steel type 316).

Hardware reinforcing shall be securely welded to frames.

Where welds would be exposed thus compromising the finish, a proprietary structural epoxy adhesive may be used (at manufacturer's option). Such connections shall demonstrate equality with a spotweld of similar size.

Hardware Preparation: Mortise, reinforce, drill, and tap to receive templated mortise hardware; reinforce for specified surface hardware in accordance with HMMA 861, HMMA 866, and definitions in ANSI/SDI A250.6.

Provide frames with one floor anchor per jamb.

Provide series M and CM frames with wall anchors; not less than three up to an opening height of 90 inches and one additional anchor for every 24" or portion thereof above 90".

PART 3 EXECUTION

3.1 EXAMINATION

Before beginning installation, verify that existing or planned substrate conditions are acceptable for installation.

Select fasteners of adequate type, number, and quality to perform intended functions.

3.2 INSTALLATION

Install frames plumb, straight, and true, rigidly secured in place and properly braced; comply with ANSI/SDI A250.11 and HMMA-866.

Grout fill frames in new masonry in accordance with ANSI/SDI A250.8, ANSI/SDI A250.11, and HMMA820-TN01. Frames installed in drywall partitions shall not be grouted.

Secure any bolted connections to adjacent construction using bolts suitable for the substrate.

Install accessories, doors, and hardware in accordance with manufacturers' templates and instructions.

3.3 PROTECTION

Protect installed products and finished surfaces from damage during construction.

Remove protective wrappings only after construction is sufficiently completed so that doors and frames will not be scratched or damaged.
