3mm Aluminum Signs are a durable, professional solution for long-term outdoor signage. Printed on rigid aluminum with a matte surface, these signs reduce glare while delivering sharp, high-contrast graphics that remain visible in various lighting conditions.
Each sign features a pre-painted bright white front for vibrant printing and a bare aluminum (mill finish) back for added durability. Optional rounded corners improve safety, while optional drill holes allow for easy installation on walls, posts, or frames. Ideal for business signage, wayfinding, construction sites, and outdoor branding where longevity matters.
PrintBuy members benefit from preferred pricing and consistent quality, making aluminum signs a smart investment for businesses with permanent or repeat signage needs.

Thanks to the strong, waterproof qualities of aluminum that help it withstand the elements, these signs are perfect for outdoor use.
Rounded corners on metal signs not only help them look more professional but also protect people from getting hurt by the corners in potential accidents.
Drilling holes into the aluminum sign makes it easier to install. These 3/8" holes can be centered on the top and bottom, on all four corners, or on the top corners only.
