What paper stocks can I choose for aluminum signs?

Aluminum signs don't use paper at all. They print onto a solid metal panel, so instead of picking a stock weight you're choosing a metal gauge and finish that matches where the sign will live.

• Material: lightweight, rust-resistant aluminum that stays flat and won't warp in humidity.
• Thickness: thinner gauges suit indoor or short-term use, while heavier gauges hold up to wind and long outdoor exposure.
• Finish: the smooth surface takes sharp, full-color graphics with UV-cured inks.
• Lifespan: the metal itself can last for years, which makes it a strong pick for permanent signage.
