A brass sign can be designed in both 3D and flat styles. A 3D brass sign is created by using materials and techniques to add depth and dimension to the design, while a flat brass sign is typically made of a flat sheet of brass and can be engraved or etched with the desired message or design. Both types can be customized and are suitable for indoor and outdoor settings. Brass signs are durable and long-lasting, making them a popular choice for businesses looking for a classic and timeless signage solution. In a 3D illuminated brass sign, LED or neon lights can be strategically placed to highlight the three-dimensional design elements, creating a striking visual effect that catches the eye. This type of sign is ideal for businesses looking to create a bold and attention-grabbing display.
