If you need a simple and effective non-lit sign, panel signs are a good option. They can be made from various materials; the most common being Crezon (a paper-smooth, painted plywood) and Alupanel®, (an aluminum plastic composite sheet) that can be attached to most surfaces. Due to these materials coming in 4 feet by 8 feet sheets, you will have seams in your sign if you make them larger than 4 feet by 8 feet.
Now, if you want a panel sign without any seams, you can fashion your sign out of an acrylic or polycarbonate sheet and put it in an aluminum extruded frame. These plastics come in rolls as high as 100 inches and as wide as 50 feet, so you can make a very large sign without seams. We can also custom-fabricate other options. On your panel signs you can add vinyl-cut or printed graphics, or even 3D lettering if you want to add a little more punch.
