Have you ever looked at a billboard, store sign, or street nameplate and wondered, what are outdoor signs made of?
Outdoor signs are essential for businesses, directions, and events, but they must be designed to endure rain, wind, and sun. Choosing the right material can make all the difference in terms of durability and appearance.
In this guide, we’ll break down the most common materials used for outdoor signs, helping you choose the best option for your needs.
Why Material Matters for Outdoor Signs
Outdoor signs face harsh conditions daily – from UV rays to rainstorms, they must remain clear, vibrant, and sturdy. The material of a sign can affect not only its durability but also its cost, weight, and visual impact.
Understanding the best materials for specific purposes can help you make informed choices that balance both function and style.
Common Materials for Outdoor Signs
There are several popular materials used to create outdoor signs. Each one has its advantages, depending on the location, weather, and type of message being displayed.
Aluminum
Aluminum is one of the most widely used materials for outdoor signs, and for good reason. It’s lightweight, durable, and rust-resistant.
- Durability: Aluminum holds up well in all weather conditions, including rain and snow, without corroding.
- Lightweight: Despite being metal, it’s easy to handle and install, making it ideal for large or high-up signs.
- Customizable: Aluminum signs can be printed in full color, coated for added protection, and shaped to fit unique designs.
This makes aluminum perfect for a wide range of applications, from business signage to parking signs.

Acrylic
Acrylic signs provide a sleek, professional appearance and are often used for high-end business signage.
- Aesthetic Appeal: Acrylic gives a polished, glossy look that makes any design pop.
- Weather-Resistant: It holds up well in most weather conditions but may not fare as well in extreme cold.
- Customizable: Available in various thicknesses, colors, and finishes, acrylic signs are fully customizable.
However, while acrylic looks great, it is more prone to scratches and can crack if handled roughly.
PVC (Polyvinyl Chloride)
PVC signs are versatile and cost-effective, making them a popular choice for short-term or budget-friendly outdoor signs.
- Affordability: PVC is a budget-friendly option, perfect for temporary or promotional signage.
- Lightweight: Easy to install, it’s great for yard signs, event banners, and retail displays.
- Customizable: Available in a variety of thicknesses and colors, it can be cut into different shapes.
PVC signs are best for short-term use, as prolonged exposure to harsh weather can cause fading or warping.
Vinyl
Vinyl is commonly used for banners, wraps, and flexible outdoor signs. It’s durable and can be printed with vibrant colors.
- Flexibility: Vinyl is ideal for banners that need to be hung or wrapped around poles and structures.
- Weather-Resistant: Vinyl is water-resistant and can withstand most weather conditions, but high winds may damage it over time.
- Cost-Effective: Vinyl is inexpensive and perfect for temporary signs, such as event banners.
While vinyl works well for banners, it’s not suitable for long-term, permanent signage, as it can tear or fade with prolonged exposure.
Wood
For a rustic or natural look, wood is still a popular choice for outdoor signage, especially in rural or eco-friendly areas.
- Aesthetic Appeal: Wood offers a warm, natural look that blends well with outdoor environments.
- Durability: When properly treated and sealed, wood signs can last for years, even in outdoor conditions.
- Customizable: Wood signs can be carved, painted, or stained to create a one-of-a-kind look.
However, wood requires regular maintenance, including sealing and staining, to protect it from moisture and insects.
Corrugated Plastic
Corrugated plastic signs (often referred to as “Coroplast”) are lightweight and affordable, making them a go-to for temporary outdoor signs.
- Lightweight: These signs are easy to transport and install, making them ideal for political campaigns, real estate listings, or events.
- Affordable: One of the cheapest options for outdoor signage.
- Weather-Resistant: Despite being plastic, they hold up well in moderate weather conditions.
Corrugated plastic is ideal for short-term use but may not hold up well under extreme weather conditions over time.

Dibond (Aluminum Composite Material)
Dibond is a combination of aluminum and a solid polyethylene core, making it incredibly durable and lightweight.
- Sturdiness: Dibond signs are stronger than standard aluminum signs and resistant to warping.
- Lightweight: Despite its strength, it’s still lightweight enough for easy installation.
- Weather-Resistant: Perfect for long-term outdoor use, Dibond signs won’t rust or corrode, even in harsh weather.
Dibond is often used for long-term, high-quality outdoor signs such as business signage, directional signs, or road signs.
Choosing the Right Material for Your Outdoor Sign
When deciding what outdoor signs are made of, it’s important to consider the following:
- Purpose: Are you looking for a temporary sign, like a banner for an event, or a long-term business sign? Temporary signs may not need the same durability as permanent ones.
- Weather Conditions: In areas with heavy rain, snow, or strong sunlight, materials like aluminum or Dibond are ideal. In milder climates, PVC or acrylic may suffice.
- Budget: For those on a budget, corrugated plastic, vinyl, or PVC might be the best options. For a longer-lasting sign, materials like aluminum or Dibond are worth the investment.
- Aesthetic: For a polished, professional look, acrylic or wood might be the way to go, while aluminum or Dibond is ideal for businesses requiring a modern, durable appearance.
What Makes a Good Outdoor Sign?
No matter the material, a good outdoor sign is:
- Clear: The text and design should be easy to read from a distance.
- Weather-Resistant: The sign should withstand weather conditions without losing its integrity.
- Durable: Depending on its use, the sign should last as long as needed without significant damage.
- On-Brand: The design and material should reflect your business or message, whether it’s sleek and modern or warm and rustic.
Installation Tips for Outdoor Signs
Once you’ve chosen the right material, proper installation is crucial for longevity:
- Secure Fastening: Make sure the sign is properly anchored to withstand wind and other environmental factors.
- Correct Placement: Install the sign where it will be easily visible to passersby but safe from excessive wear and tear.
- Regular Maintenance: Check for signs of wear, especially if the sign is made from wood or vinyl, and perform routine cleaning or repairs as needed.
Maintenance Tips for Outdoor Signs
To keep your outdoor sign looking great and functioning well:
- Clean Regularly: Use a gentle soap and water solution to clean dirt and grime off the surface.
- Reapply Coating: For materials like wood or acrylic, reapplying a protective coating can help preserve their appearance.
- Check for Damage: Inspect your sign periodically for cracks, fading, or other signs of wear and address them promptly.
