Outdoor signs play a crucial role in conveying messages, promoting businesses, and guiding visitors. They are exposed to various weather conditions, making their durability and resilience vital factors. Choosing the right material for outdoor signs can ensure they withstand the elements and retain their visual appeal over time. In this article, we will explore some of the best materials for creating long-lasting and effective outdoor signs.


Aluminum is one of the most popular choices for the material for outdoor signs due to its exceptional durability and resistance to rust and corrosion. It can withstand harsh weather conditions, making it suitable for both hot summers and cold winters. Aluminum signs can last for many years, and their lightweight nature allows for easy installation. Additionally, they can be custom printed with vivid graphics, making them eye-catching and perfect for promoting businesses and events.


Dibond is a composite material consisting of a solid polyethylene core sandwiched between two thin aluminum sheets. This combination results in a lightweight yet robust sign option. Dibond signs are resistant to fading, chipping, and warping, making them ideal for long-term outdoor use. Their smooth surface ensures high-quality printing, making them great for displaying intricate designs, logos, and photographs.

PVC (Polyvinyl Chloride)

PVC is a cost-effective option for outdoor signs. It is a durable plastic material that is resistant to moisture, chemicals, and UV rays. PVC signs can withstand extreme temperatures and are relatively lightweight, making installation hassle-free. Although not as sturdy as aluminum or Dibond, PVC signs are excellent for temporary outdoor promotions, events, and directional signage.

Corrugated Plastic (Coroplast)

Corrugated plastic is a versatile and budget-friendly material, often used for yard signs, real estate signs, and temporary outdoor advertising. It is made from twin-wall plastic sheets, providing it with moderate durability. While not as long-lasting as aluminum or Dibond, coroplast signs are easy to transport, lightweight, and weather-resistant. They are an excellent choice for short-term outdoor campaigns or events.


Acrylic, also known as Plexiglas or PMMA, is an attractive option for high-end outdoor signs. Its transparent nature and glass-like appearance add a touch of elegance to any signage. Acrylic signs are UV-resistant, ensuring that they won’t fade or discolor over time. However, they are more suitable for sheltered outdoor areas, as prolonged exposure to harsh weather can cause them to become brittle.


For a rustic and charming appeal, wood signs are a popular choice. Cedar, redwood, and marine-grade plywood are commonly used for outdoor wooden signs due to their natural resistance to decay and insects. However, wood requires regular maintenance and protective coatings to withstand outdoor conditions effectively.


Selecting the right material for outdoor signs is crucial to ensure longevity and visual appeal. The choice depends on the intended use, budget, and specific environmental factors. Aluminum and Dibond offer superior durability, making them excellent choices for permanent outdoor signage. PVC and corrugated plastic are more budget-friendly and ideal for temporary signage needs. Acrylic adds a touch of sophistication to upscale outdoor settings, while wood exudes a classic and charming aesthetic.

Before investing in outdoor signs, consider the intended purpose, location, and longevity requirements to make an informed decision about the most suitable material for your specific needs. With the right material, your outdoor signs will effectively convey messages and promote your business for years to come.
