2.03 MATERIALS FOR FIELD-ASSEMBLED METAL PANELS<br />
A. Metallic-Coated Steel Sheet Prepainted with Coil Coating: Steel sheet metallic coated by the<br />
hot-dip process <strong>and</strong> prepainted by the coil-coating process to comply with<br />
ASTM A 755/A 755M.<br />
1. Zinc-Coated (Galvanized) Steel Sheet: ASTM A 653/A 653M, Structural Steel (SS),<br />
Grades 33 through 80 (230 through 550), with G90 (Z275) coating designation.<br />
2. Surface: Smooth, flat finish.<br />
3. Exposed Finishes: Apply the following coil coating, as specified or indicated on Drawings:<br />
a. High-Performance Organic Finish (2-Coat Fluoropolymer): AA-C12C40R1x (Chemical<br />
Finish: cleaned with inhibited chemicals; Chemical Finish: conversion coating;<br />
Organic Coating: manufacturer's st<strong>and</strong>ard 2-coat, thermocured system consisting of<br />
specially formulated inhibitive primer <strong>and</strong> fluoropolymer color topcoat containing not<br />
less than 70 percent polyvinylidene fluoride resin by weight). Prepare, pretreat, <strong>and</strong><br />
apply coating to exposed metal surfaces to comply with AAMA 2605 <strong>and</strong> with coating<br />
<strong>and</strong> resin manufacturers' written instructions, except as modified below:<br />
b. Concealed Finish: Apply pretreatment <strong>and</strong> manufacturer's st<strong>and</strong>ard white or lightcolored<br />
backer finish, consisting of prime coat <strong>and</strong> wash coat with a total minimum<br />
dry film thickness of 0.5 mil (0.013 mm).<br />
2.04 THERMAL INSULATION FOR FIELD-ASSEMBLED METAL PANELS<br />
A. Metal Building Insulation: ASTM C 991, Type I, or NAIMA 202, glass-fiber-blanket insulation;<br />
0.5-lb/cu. ft. (8-kg/cu. m) density; 2-inch- (50-mm-) wide, continuous, vapor-tight edge tabs;<br />
<strong>and</strong> with a flame-spread index of 25 or less.<br />
2.05 DOOR AND FRAME MATERIALS<br />
A. Cold-Rolled Steel Sheet: ASTM A 1008/A 1008M, Commercial Steel (CS), Type B, suitable<br />
for exposed applications.<br />
B. Hot-Rolled Steel Sheet: ASTM A 1011/A 1011M, Commercial Steel (CS), Type B; free of<br />

C. Metallic-Coated Steel Sheet: ASTM A 653/A 653M, Commercial Steel (CS), Type B; with<br />
G60 (Z180) zinc (galvanized) or A60 (ZF180) zinc-iron-alloy (galvannealed) coating designation.<br />
2.06 MISCELLANEOUS MATERIALS<br />
A. Fasteners: Self-tapping screws, bolts, nuts, self-locking rivets <strong>and</strong> bolts, end-welded studs,<br />
<strong>and</strong> other suitable fasteners designed to withst<strong>and</strong> design loads. Provide fasteners with<br />
heads matching color of materials being fastened by means of plastic caps or factory-applied<br />
coating.<br />
1. Fasteners for Metal Roof Panels: Self-drilling or self-tapping, zinc-plated, hex-head carbon-steel<br />
screws, with a stainless-steel cap or zinc-aluminum-alloy head <strong>and</strong> EPDM or<br />
neoprene sealing washer.<br />
2. Fasteners for Metal Wall Panels: Self-drilling or self-tapping, zinc-plated, hex-head carbon-steel<br />
screws, with nylon or polypropylene washer.<br />
