What are A-frame signs?
A-frame signs, also known as sandwich boards, are portable folding signs designed for indoor and outdoor advertising. Businesses commonly use them to display promotions, directions, menus, event announcements, and branding messages in areas with pedestrian traffic.
Signicade® signs are a popular type of plastic A-frame sign built for outdoor durability and weather resistance. While all Signicades are A-frame signs, not all A-frame signs are Signicades.
