Fastener shall be assembled with EPDM washer to insure a waterproof seal. The ULTIMATE™ fastener is available color coated and non-color coated. These fasteners are applicable for use with fiberglass blanket insulation for 0” to 4” thick.
6.2.1.3 Self-drilling structural screws shall be 410 corrosion resistant stainless steel No. 12-14 x 1 1/4” Hex Head with the EPDM washer. Color coated and non-color coated heads are available. The fasteners are applicable for use with insulation from 0” to 4” thick.
6.2.1.4 Self-drilling sidelap, panel to panel screws shall be No. 14 x 7/8” with EPDM washer. This fastener is used regardless of panel type. The finish on this fastener will be provided to match the self-drilling structural screws specified.
6.2.1.5 Self-drilling structural screws when used on the walls with 6” fiberglass blanket insulation shall be No.12-14 x 1 7/8” Stand-off Traxx/3. These fasteners are available with both the OxySeal II and the ULTIMATE finishes.

6.3 GUTTER, DOWNSPOUTS, AND RELATED FLASHING
6.3.1 Eave Line Gutters: The gutters shall be 24 gauge AZ50 aluminum-zinc coated steel substrate with a pre-painted finish.
6.3.2 Downspouts: Downspouts shall be 26 gauge aluminum-zinc alloy coated steel pre-painted, rectangular in shape.

6.4 CLOSURES AND SEALANTS
6.4.1 Closure Strips: The corrugations of the roof and wall panels shall be filled with solid or closed cell, non-shrinking, performed, neoprene or polyethylene closures at the eave, ridge and rake when required for Weathertightness.
6.4.2 Metal Closures: The corrugations and pan area of both Ultra-Dek and Double-Lok Roofing Systems and the BattenLok Standing Seam Roofing System shall be filled with formed metal closures. The outside closures shall be formed from 24 gauge steel. The inside closures shall be formed from 18 gauge steel. The closure exterior shall be aluminum-zinc alloy or pre-painted AZ50 aluminum-zinc alloy coated steel.
6.4.3 Sealants: Vistasheen II roof panels shall be sealed as indicated on A&S Erection Drawings with 3/32” x 3/8” wide tape sealer. This material shall be butyl base elastic compound with a minimum solid content of 99%, Schnee-Morehead No. 5225 or equal. The sealer shall be non-staining, non-corrosive, non-shrinking, non-oxidizing, non-toxic and non-volatile. The service temperature shall be from –60° F to 300° F.
6.4.4 Sealants: Ultra-Dek, Double-Lok, and BattenLok systems endlap, ridge, gable and eave sealers are butyl-based pressure sensitive 7/8” x 3/16” tape mastic, non-staining, non-corrosive, non-volatile and non-toxic. The tape is 100 polyisobutylene-isoprene meeting the performance requirements of Federal Specification TT-C-1796A, Type II, Class B. Service temperature is from –60° F to +275° F.
6.4.5 Caulk: All gutter and downspout joints, rake flashing laps, ridge flashing laps, doors, window, and louvers shall be sealed with white or burnished slate pigmented polyurethane caulk. It shall meet or exceed the requirement of Federal Specification TT-S-00230C, Type II, Class A.

SECTION 7. PAINTING
7.1STRUCTURAL PAINTING
7.1.1 All uncoated structural steel shall be cleaned of all foreign matter and loose scale in accordance with SSPC-c and given a one mil coat of A&S Building System’s red oxide primer. Primer shall meet or exceed Federal Specification SSPC 15-68T (replaced Federal Specification TT-P-636D). This coating is not intended or represented as a finish coat.
7.1.2 All secondary structural framing shall be pre-painted coil stock. The coil stock shall be completely cleaned and treated with an iron phosphate process before the coil is coated with red oxide polyester paint. With a minimum dry film thickness of 0.5 mil, this coating process meets or exceeds the performance requirements of Federal Specification SSPC 15-68T. This coating is not intended or represented as a finish coat.
