Aluminum Specs.docx

This is a product specification document from Iowa Prison Industries establishing technical requirements for aluminum sheets used in sign manufacturing. The specification, originally issued in January 1996 and most recently revised on December 16, 2021, details material requirements, quality standards, and approved dimensions for multiple aluminum sheet SKUs. All aluminum must be new domestic material conforming to ASTM B-209, either alloy 5052-H38 or 6061-T6, and must be alodized with Alodine 1200, Chromate 5015, or an equivalent chemical conversion treatment qualified under U.S. Specification MIL-C-5541B or ASTM B449-67, Class I or II. Sheets must be squared with dimensions as ordered (minimum thickness, length, and width acceptable; undersized material will be rejected). The specification covers sixteen distinct aluminum sheet SKU variants ranging from 0.063 to 0.125 inches in thickness, with widths from 30 to 60.5 inches and lengths of 120 or 144 inches, with sheet limits per skid varying from 25 to 100 sheets depending on thickness and size.

Vendors must provide mill certification with each shipment and comply with all Iowa Department of Transportation and Minnesota Department of Transportation specifications before final acceptance. Material must be shipped on open, tarped flatbed trucks only, with skid weights not exceeding 3,000 pounds and unloaded via forklift. Each skid must include a minimum of three runners measuring at least 3 inches by 3 inches running the full skid length. Sample material may be required for inspection prior to shipment. Any material failing to meet these specifications will be returned to the vendor at the vendor's expense. The specification also references several Iowa Department of Transportation item numbers with corresponding dimensions for standard-sized aluminum sheets.
