Three dimensional signage (sometimes called 3D signs) adds an element of depth to a flat sign't height and width.
The shape, shadows and shading of 3D letters, logos and graphics catch the eye like no two dimensional sign can.
A freestanding sign in excess of eight feet in height that is detached from a building and is supported by one or more structural element(s) which is architecturally similar to the design of the sign.
Channel letters are custom made metal or plastic letters commonly used in exterior signage on public and commercial buildings and often internally illuminated.
Unlit three dimensional letters that are applied to sign panels or monuments are usually referred to as dimensional letters.
A billboard is a large advertising structure typically found in high-traffic areas such as alongside busy roads.
Billboards present large advertisements to passing pedestrians and vehicles.
LED lit signs last longer. LEDs have a longer life span compared to neon and fluorescent lighting. In fact they last 25 times longer than incandescent lights and offer thousands of more hours of display time over neon. LEDs also do not risk leakage of gasses which means the lights don't go dim like neon lights can.
Way-finding signage is concerned with helping to direct you from point to point, or confirming your progress along a route. Way-finding signage in other words, is not advertising signage or informational signage such as trains arrival timetable.
