Carved and sandblasted signs are made two different ways but both have great benefits. A carved sign is when all of the lettering, borders, or logos are grooved or engraved into the material of your choosing to create the message you are wishing to display. A sandblasted sign is when the message is "masked" in order to blast away the background material giving it a 3D image. Essentially one sign sticks out while the other has an indented appearance.
Both signs are long-lasting and can look absolutely beautiful. A benefit of using these unique signs is that they help you stand out from the industrial feel that most businesses have while also having a more modern, 3D look to them.
