A common question we get asked is the difference in the various substrates used for signs. Below is a list of some of the more common materials used and a brief product description.

The Coroplast™ name is known throughout the Sign Industry for a consistent high quality printable surface. The only down side is that the corrugation shows through the graphic at close distance. Corrugated plastic is a great economical solution for indoor or outdoor signage and is our most used substrate. Typically we use 1/8″ to 1/4″ thick coroplast. Coroplast
A strong, lightweight and easily cut material. It consists of three layers — an inner layer of polystyrene clad with outer facing of either a white claycoated paper. The foam is fairly easily crushed and edges bent, so you must be careful with storage and transporting. Typically we use .15″ to .50″ thick Formcore. Foamcore
A durable lightweight board, it consists of a core of polystyrene foam bonded on both sides with wood fibers impregnated with resin. This provides durability and rigidity as well as moisture resistance.The foam used on this product holds up much better then Foamcore in storage and transporting. Typically we use .15″ to .50″ thick Gatorfoam Gatorfoam


Commonly referred to as plexiglass. Great for indoor use and has a polished finished and smooth texture. It is manufactured in several thicknesses and may be finished with beveled edges, polished or graphics may be applied to the second surface. Typically we use 1/8″ to 1/2″ acrylic.


A durable product composed of white aluminum blank sheets on both sides with corrugated plastic in between. This material is perfect for long-term outdoor applications.


This lightweight material is great for indoor or outdoor applications. The major benefit is its duration. Aluminum can be used anywhere and is recommended in applications where the sign must last five years or more. Aluminum can be purchased in several colors or textured metals.
