C.
Panels shall be fabricated in full lengths from ridge to eave without end laps. Panels shall be 16” wide maximum with
concealed anchors that resist wind uplift yet permit expansion and contraction with temperature changes. Standing
ribs 3” high shall have a continuous groove capillary break. Ribs shall be securely locked over anchor clips with a
field operated, electrically driven roll-forming tool. Individual panels shall be removable for replacement of damaged
material.
Smooth, pre-painted Aluminum Alloy 3004, Embossed, H 35/36, H-274 temper MINIMUM in 0.040” thickness in
accordance with ASTM-B-209. Softer alloys and tempers will NOT be acceptable.
a. High Performance Organic Finish: AA-C12C42R1x (Chemical Finish: cleaned with inhibited chemicals;
Chemical Finish: acid-chromate-fluoride-phosphate conversion coating; Organic Coating: as specified below).
Prepare, pretreat, and apply coating to exposed metal surfaces to comply with coating and resin manufacturers’
written instructions.
1. Fluropolymer Two-Coat System: Manufacturer’s standard two -coat, thermocured system consisting of
specially formu lated inhibitive primer and fluropolymer color topcoat containing not less than 70 percent
polyvinylidene fluoride resin by weight; complying with AAMA 2605.
2. Dry film thickness (exclusive of primer): 0.8 mil. + minimum.
D.
Flashing and Trim shall be same material type and finish as the roof panel. Minimum thickness shall be the same as
the roof panel.
E.
Panel Sealant:
1. Sealant Tape: Pressure-sensitive, 100 percent solids, gray polyisobutylene compound sealant tape with
release-paper backing. Provide permanently elastic, non-sag, nontoxic, non-staining tape ½ inch (13 mm) wide
and 1/8 inch (3 mm) thick.
2. Joint Sealant: ASTM-C-920; elastomeric polyurethane, polysulfide, or silicone sealant; of type, grade, class,
and use classifications required to seal joints in metal roof panels and remain weathertight; and as
recommended in writing by metal roof panel manufacturer.
3. Butyl-Rubber-Based, Solvent-Release Sealant: ASTM-C-1311.

MISCELLANEOUS MATERIALS
A. Anchor Clips : Shall be Series 3000 non-magnetic stainless steel or aluminum coated with nylon (no carbon
coated steel components whatsoever) to minimize wear from thermal movement. Fasteners in supports and
screws installed in clips shall be fully recessed so that no sharp edges come in contact with the roof material.
Clips shall be of two-piece design, designed to allow for expansion and contraction of the roof relative to the
structure throughout the temperature range specified in performance criteria.
1. Exposed fasteners shall match the finish of the panel system and shall be aluminum or stainless steel. For
weathertightness, screws shall have separate washers with hot bonded neoprene faces, and pop-rivets
shall be set in wet sealant. Exposed fasteners shall be a minimum #14 size screw or 3/16” diameter rivet.
B. Preformed steel closures at ridges and field cut closures at hips matching the finish of the roof flashing.
