When choosing a substrate for building signs, there are many factors to consider. Here is a rundown of the most popular choices and their best uses.
Aluminum
Aluminum is available in sheets or aluminum composite material (ACM) panels. ACM is made of two thin aluminum sheets with a solid polyethylene core. They are used for street, highway, and parking garage signs. Both options offer durability and have a sleek, professional appearance.
Acrylic
Acrylic is made from a thermoplastic polymer. It’s a strong, clear material used for both indoor and outdoor signs. It is available in clear, frosted, and opaque colors, making it ideal for everything from office door signs to illuminated signs.
Coroplast
Coroplast is a lightweight corrugated plastic. It is made of two plastic sheets joined by flutes (ridges). Coroplast is often used for temporary outdoor signs, such as yard signs and political campaign signs. They are ideal for short-term use because they are lightweight and easy to transport.
High-Density Urethane Foam (HDU)
HDU is a closed-cell (high-density) rigid foam board. It is affordable and easy to print on. It is typically used for political campaigns, real estate signs, and special events.
Vinyl
Vinyl is made of PVC, but it is available in a wider range of colors and finishes than traditional PVC. Vinyl can be used for both indoor and outdoor signs. It’s often used for office signs, window signs, and car wraps.
MDO Wood
MDO wood is a medium-density fiberboard coated with a thin layer of plywood. It’s often used for storefront and real estate signs. MDO wood is durable and weather-resistant, making it ideal for long-term use.
Polystyrene
Polystyrene is a rigid, lightweight plastic made from styrene monomers. Polystyrene is easy to cut and print on, making it a versatile option for everything from temporary event signs to permanent office signs.
Fiberglass-Reinforced Plastic (FRP)
FRP is a composite material made of glass and resin. FRP is often used for dimensional letters, menu boards, and wayfinding signs. It’s strong, durable, and weather-resistant, making it an ideal choice for outdoor signs.
Which Material is Best?
There is no one “best” material for building signs. The ideal material for the sign will depend on specific needs and preferences. Consider the following factors when choosing a sign substrate:
- Visual Appeal: What type of message do you want the sign to project? Some materials, like aluminum, have a sleek and professional appearance. Others, like coroplast, are more casual.
- Durability: How long should the sign last? Some materials, like aluminum, are designed for long-term use. Others, like vinyl, are more temporary.
- Cost: How much should a company spend on signs? Some materials, like HDU, are more expensive than others, like coroplast. A sign professional advises companies on these choices.
- Weight: How lightweight is the sign? Some materials, like aluminum, are heavier and more difficult to move. Others, like coroplast, are much lighter and easier to handle.
