Aluminum composite signs are a popular choice for outdoor signage due to their durability and versatility. They typically consist of a composite material made of two thin aluminum sheets bonded to a solid polyethylene core. These signs are known for being weather-resistant and relatively lightweight while still being strong and rigid.
The 3mm thickness indicates the overall depth of the sign—this measurement is the combined thickness of both aluminum sheets and the core. This thickness is commonly used for signs that need to balance durability with weight, making them suitable for various indoor and outdoor applications like advertising boards, directional signs, real estate signs, and more.
