PART 2 PRODUCT
2.01 ACCEPTABLE MANUFACTURERS
A. Berridge Manufacturing Company, Houston, Texas.
B. Substitutions shall fully comply with specified requirements.
2.02 SHEET MATERIALS
A.  Prefinished metal shall be Aluminum-Zinc Alloy Coated (AZ-50 Galvalume®) Steel Sheet, 24-Gauge, ASTM 792-08, Grade 40, yield strength 40 ksi min.
B.  Finish shall be full strength Kynar 500® or Hylar 5000™ fluoropolymer coating applied by the manufacturer on a continuous coil coating line, with a top side dry film thickness of 0.75 ± 0.05 mil over 0.20 ± 0.05 mil prime coat, to provide a total top side dry film thickness of 0.95 ± 0.10 mil. Bottom side shall be coated with a primer and beige urethane coating with a total dry film thickness of 0.35 ± 0.05 mil. Finish shall conform to all tests for adhesion, flexibility, and longevity as specified by the Kynar 500® or Hylar 5000™ finish supplier.
C.  Color shall be _________________.
D.  Strippable film shall be applied to the top side of all prefinished metal to protect the finish during fabrication, shipping and field handling. This strippable film MUST be removed immediately before installation.
E.  Unpainted metal shall be  Aluminum-Zinc Alloy Coated (AZ-55 Acrylic Coated Galvalume®) Steel Sheet, 24-Gauge, ASTM 792-08, Grade 40, yield strength 40 ksi min., with clear acrylic coating on both sides of material.
F.  Field protection must be provided by the contractor at the job site so stacked or coiled material is not exposed to weather and moisture.
G.  Flashing maybe factory fabricated or field fabricated. Unless otherwise specified all exposed adjacent flashing shall be of the same material and finish as panel system.
Note: The rolling process of sheet metal results in inherent surface unevenness referred
to as “oil-canning.” This condition is also caused by several factors including thermal expansion and contraction, dark colors, both medium and high-gloss finishes, and uneven substrate. “Oil-canning” in itself is not sufficient cause for material rejection.
2.03 ACCESSORY MATERIALS
A. Fasteners: [Galvanized Steel] [Stainless Steel] [Cadmium Plated Steel] with washers where required.
2.04 FABRICATION
A. All exposed adjacent flashing shall be of the same material and finish as the roof shingles.
B. Hem all exposed edges of flashing on underside, 1/2 inch.
