Do you ever wonder how signs play a big part in your life? Yes, I’m talking about storefront signs, menu board signs, road signs, movie house signs, restroom signs, election signs, etc. Wherever you go, there are various types of signage installed for different purposes. They are a useful source of information and guidance.

Experts say that a huge chunk of information transmitted to the human brain is visual, and a lot of people are six times more likely to recall visual than auditory information. As such, visual signs are perfect to relay messages that you want other people to know and remember.

The materials you must use for your signage are also equally important as the message you display on them. For a little help, I will walk you through the top materials that you can use for your custom signage.


Three Best Materials for Indoor Signs

Indoor signs are ideal to use for business establishments, professional offices, and government buildings. Here are the best signage materials that you can use for your indoor needs.

Ultra Board

Ultra board is touted as one of the most durable materials for indoor use. It is made with a polystyrene plastic covering that can resist warp and scratch. You can also cut or fold it for different purposes, e.g., freestanding life-size cutouts that often feature celebrity endorsers.

Foam Core

If you want temporary indoor signage, this material is one of the best choices. Foam core is made of a dense piece of foam propped between two thick layers of matte paper. It has a reduced glare matte finish and can be used for various purposes.


You can see this material used for temporary business displays, classroom projects, and science fair exhibitions.


This type of signage material is firm and lightweight, which makes it a versatile choice for indoor use. Gatorboard is made of a dense piece of foam propped between two wood fiber veneers that are absorbent to full-colored inks. It can resist dent, water, and scratch, adding to its structural durability.


You can see this type of material used for kiosk and conference displays or as mounted photos and posters.


Three Best Materials for Outdoor Signs

Outdoor signs are everywhere. But the question is: what are the top materials used to make these signs that you see outdoors?

Corrugated Plastic

Corrugated plastic is also known as plastic cardboard or for its brand name Coroplast. An ultra-lightweight corrugated sheet propped between two smooth plastic sheets makes this type of exterior signage material. You can form it as to your desired size and shape, and this material is durable and resistant to water and weather.


Corrugated plastic is the best option to use for car wash signs, yard signs, special holiday signs, storefront signs, election signs, etc. You can also mount it onto frames or H-stakes.

Sintra Board

If you want a material that can withstand harsh weather conditions and keep up its structural integrity through long-term exposure to the elements, the Sintra Board is ideal for that purpose. This material made from PVC or polyvinyl chloride is rigid, weatherproof, and non-flexible. It can resist bending and warping and has a low glare matte finish that is absorbent to colors.


This signage material is an aluminum composite made of polyethylene core placed between two aluminum sheets. Dibond resembles metal due to its durability and structural integrity. You can cut or form it into various shapes and sizes, allowing you to make your signage stands out.

Dibond is rigid, lightweight, non-corrosive, and weather resistant. You can also choose this material from a variety of colors and finishes, such as glossy, mirrored, or matte finish. The appeal and versatility of Dibond make it as one of the best choices for exterior business signage. If you want to know more about outdoor signage, you can visit Shieldco custom business signage for that purpose.


Can You Recycle Those Signage Materials?

Most signage materials are recyclable! For instance, signs made of metal H-stakes and corrugated plastic can be recycled by separating the stakes and dropping them to the nearest recycling center in your place.


The primary component of most plastics called polypropylene is non-biodegradable, so it is wiser to recycle them than just throwing them anywhere. In this way, you can provide a significant contribution to our environment.



You can see signs wherever you go. They are a constant fixture when you visit stores, restaurants, government offices, hospitals, etc. Signs provide us with information and guidance. But we know little about the materials used for these signs.


If you are someone who needs to have signage for a particular purpose, you need to know the various signage materials. There are specific materials for indoor and outdoor use. For indoor use, the top choices are ultra board, foam core, and gatorboard. For outdoor use, on the other hand, we have dibond, corrugated plastic, and Sintra board.
