11'x10.5' sandblasted HDU, the main body of this sign is 2- 1 1/2"x4'x10' HDU sheets backed with alumilite and steel framing. All location signs are 1" HDU and are removable. We fabricated the frame using 4"x6" steel tubing, with 1"x2" tubing across the back. Sign & steel frame weigh aprox. 1000-1200 pounds. Thanks to Jerry Mathel for help with figuring the footing.
