Is metal a good sign substrate?

Metal can be a good substrate for signs because it is durable and can withstand outdoor conditions. Additionally, it can be painted or printed on and is resistant to fading and wear. However, it is also relatively heavy and may require specialized tools for installation. Other materials, such as PVC or acrylic may also be suitable alternatives depending on the specific application and desired aesthetic.

In Hawaii, aluminum is a preferred substrate because it will not rust and does not require periodic regular treatments. It’s also relatively inexpensive compared to steel. One downside is that it’s thin and therefore lacks dimensionality. We use a lot of aluminum for real estate signs and signs installed flat on a building, for example.
