About this file
This is a technical specifications drawing for aluminum sign blanks prepared by the City of Milwaukee's Traffic Engineering Division, Electrical Services. The document, designated Drawing F-94-528T, establishes comprehensive specifications for traffic sign blank manufacturing to support the City's three-year vendor contract effective January 11, 2027, with two optional one-year extensions available upon mutual consent. The specifications detail manufacturing requirements for multiple aluminum sign blank configurations in varying sizes and gauges, with 26 distinct product line items ranging from small 6" x 12" blanks to large 48" x 48" blanks, encompassing rectangular, octagonal, and triangular shapes.
The specifications require that all sign blanks be manufactured from 5052-H38 flat sheet alodized aluminum with a gauge tolerance not exceeding plus or minus 4 percent. Critical performance requirements include panel flatness, smooth finish suitable for reflective sheeting application, 0.5-inch diameter holes, 2-inch rounded corners unless otherwise noted, and edges and holes free from burrs. The document establishes two aluminum gauges (.080 and .100 inch) across the product line and includes detailed dimensional drawings with tolerance specifications. All blanks must be ready for reflective sheeting application and meet strict quality standards regarding flatness, surface finish, and dimensional accuracy to ensure compatibility with traffic sign applications throughout the City of Milwaukee.
