All Hall Signs aluminum blanks are manufactured at our Bloomington facility per U.S. Bureau of Public Roads Standards. Our standard blanks have 3/8" holes for mounting and radius corners in accordance with the Federal Standard Highway Signs Manual. The aluminum substrate base for our aluminum sign blanks is chemically treated to add longer life and weather resistance. Reflective Aluminum Blanks are covered with material on one or both sides. Choose from three grades of reflective material in seven standard highway colors.
Fine blanks, not butchered up like some sources. The HIP sheeting was expertly applied and were trimmed very cleanly and nicely. My order was followed up very professionally and I received same in the time frame that was established. One sign blank was slightly damaged in shipment and a simple phone call, with photo of damage was all it took and the blank was replaced in 2 days.
