There are many styles of monument signs, made from a variety of materials. Mostly the standard illuminated monument signs are aluminum fabricated, however, synthetic foams like HDU are very common. Wood post and panel signs also serve as monument signage. No matter which type you choose, you're making a good business decision, as it helps attract customers to your business.
One of the most challenging parts of my job as a graphic designer is designing unique looking signs. Creating new and insteresting styles and designs provides our customers a unique sign, and not a pre-made monument. Architectural signs add value to the property and business.
Large monument signs that you see along the side of highways are called Pylon signs, and typically have an illuminated LED screen for moving text and images. These are quite elaborate, and extremely effective at marketing your business. Shopping malls and large strip malls also use these pylon style monument signs.
Monument signs are the best way to attract attention!
