This type of sign is named so for a reason as it literally projects from a building at an angle, normally 90 degrees. Projecting signs are a very effective form of signage as they can usually be seen at a further distance from your main sign and are double sided to be seen from both directions of oncoming traffic and pedestrians.
They can be manufactured from different materials, in a variety of shapes, sizes, with a choice of finishes. Illuminated or non-illuminated can both be manufactured from wood, metal, acrylic and many other materials and can create something unique for your brand and business.
