2.02 PRODUCT SUBSTITUTIONS
A. Requests to use alternate systems shall be submitted in writing to the project designer at least 10 days prior to bid. Request shall demonstrate proposed substitution meets or exceeds specified performance requirements. Descriptive data must be included in the submittal request.
B. Manufacturer listed in this section is prequalified. Substitution of another manufacturer’s products for those specified shall not be allowed at anytime during construction.

2.03 MATERIALS AND FINISHES
A. Panel materials
1. 24, 22, 20 gauge Grade 50, 50 ksi yield strength structural steel with G90 hot dipped galvanized, or aluminum-zinc alloy coating, both conforming to ASTM A 653 or ASTM A 792.
2. 0.032, 0.040, or 0.050”, 3004-H36 or equivalent aluminum alloy conforming to ASTM B 209
B. Texture: Panels shall be smooth.
C. Finish: Refer to manufacturer’s standard color chart to determine appropriate finish and color. All panels will receive a factory applied finish coat conforming to the following:
