Sacramento, CA – ACM vs. Fiberglass: Which is Better for Signs | Sign Store News

There are many substrates (materials) used in the creation of signs. ACM and Fiberglass are two of these materials, and both have their advantages and disadvantages.

What is ACM?

ACM is a lightweight, durable metal material with good thermal insulation properties which can be used for indoor and outdoor signs. It is produced from two thin layers of aluminum bonded to a thermoplastic core. ACM is often used for fabrication projects requiring flatness, rigidity, and stability. The material is also available in various finishes, from matte white to brushed stainless steel.

The main drawbacks to ACM include significant weight, and the potential for dents, and scratches.

What is Fiberglass?

Fiberglass is a lightweight material which is easy to fabricate and typically less expensive than ACM. Fiberglass is crafted by intertwining glass fibers and combining them with a plastic resin, which results in a strong yet lightweight material.

Its superior strength makes it ideal for signs exposed to severe weather conditions such as high winds, hailstorms, and heavy snow. It is also corrosion-resistant and won’t become damaged in harsh environments such as oceanfront properties.

The main drawbacks to fiberglass include the degree of difficulty to print, colors can fade over time, and it’s not as fire-resistant as ACM. Additionally, because of its lightweight nature, it can be tricky to mount securely in windy areas.

Which is the Best Option?

When deciding between ACM and fiberglass for your signs, consider the application in which it will be used. For example, if you need a sign which won’t corrode or dent after being exposed to extreme weather conditions, then fiberglass is the choice.

However, if you’re looking for a material which offers superior fire safety ratings, ACM is the better choice.

Fiberglass is considerably lighter than ACM and more resistant to damage, but due to its porous nature, it is not as durable and may require more frequent maintenance.

In terms of cost, ACM is generally more expensive than fiberglass. However, this is offset by its superior durability and quality.

ACM is generally the preferred choice for exterior signs, while interior signs are better suited for fiberglass.

No matter which material you choose, it’s important to be aware of its pros and cons to make an informed decision. Taking the time to weigh your options will help you select the best material for your project.
