Aluminum Signs

When you need signage that will truly stand the test of time, look no further than custom printed aluminum signs. Unlike plastic or wood that can crack, warp, or degrade over the years, heavy-duty metal signs offer unparalleled structural integrity and strength. Whether you need permanent wayfinding signs for a corporate campus, reserved parking markers for a retail storefront, or rugged property warning signs, custom aluminum signage delivers a professional, authoritative message that lasts.


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.
