What are aluminum sign panels?
Aluminum Signs Panels, aka aluminum sandwich board, are printed with UV inks and comprised of two .020" aluminum sheets with a polyethylene core, resulting in a total thickness of 1/8" (3mm). They are lightweight and come in two pre-painted colors: White & Brushed Silver. Drill hole options are available for quick and easy attachment to posts, fences, walls and a variety of surfaces. Aluminum Signs Panels are suitable for both indoor and outdoor use. Common uses include: real estate signage, customer/handicap notices, directional signs and much more.
