Aluminum signs are the go-to for outdoor business signs that stay up. They're rigid, rust-proof and easy to mount on a wall, fence or post. Use them for office hours, parking rules, property notices, safety signs and building numbers.
Choose your metal, pick a size, add corner holes if you plan to screw it up, and upload your design.

Common uses for aluminum signs

Signs that stay up
If a sign will live outside for a while, aluminum is a solid pick. It's the same type of panel used on many real estate post signs.
- Office hours and door signs
- Reserved and customer parking signs
- Private property and no trespassing signs
- Safety signs for job sites and warehouses
- Building numbers and business ID signs
Tip. For parking and safety signs, use high contrast, like black on white or white on red, and keep the wording short. Our guide on how to design a readable sign has more pointers.
Before you order
- Measure the wall, door or post where the sign will go
- Decide how you'll mount it, and add corner holes if you'll use screws
- Choose reflective if the sign needs to be seen at night
- Pick double-sided if people will see the sign from both directions
- Keep the wording short and the text large
