External dock door sign blanks are produced from white 3mm aluminum composite sign material (ACM). ACM is composed of two .035" aluminum sheets over a polyethylene (PE) core.
The unique properties of ACM means it can be used outside and can withstand environmental effects much better than alternative materials.
The material can be drilled and works with most adhesive for installation on external walls over warehouse dock doors.
Face size: 12" x 24"
