If you’ve been in the market for a new service body, you’ve likely come across both fiberglass and aluminum options. While aluminum has been the traditional choice in recent years, fiberglass is quickly gaining popularity thanks to its many advantages.

Let’s take a closer look at why fiberglass service bodies are the superior option.

What’s the Difference Between Aluminum & Fiberglass Bodies

When it comes to selecting a service body for your work truck, aluminum or fiberglass are two options you have.

Aluminum is also susceptible to dents and scratches, so it may not be the best choice if you need a body that will retain its like-new appearance over time.

On the other hand, fiberglass service bodies are much more resistant to damage. They’re also easier to maneuver into place. In addition, fiberglass service bodies won’t rust or corrode like a steel body or an aluminum body can, so they’re a good choice if you need a body that will stand up to the elements.

The Pros and Cons

Service bodies are one of the most important components of any work truck. They provide secure, weather-resistant storage space for tools and equipment, and they can be customized to suit the specific needs of any business.

Many businesses choose between aluminum and fiberglass models when choosing a service body. Each material has its own advantages and disadvantages, but fiberglass service bodies offer several benefits that aluminum simply cannot match.

  • Fiberglass is more resistant to corrosion, denting, and scratching.
  • Perhaps most importantly, fiberglass is much less conductive than aluminum, making it safer to use around sensitive electronic equipment.
  • Fiberglass service bodies are also easier and less expensive to repair than their aluminum counterparts.
  • For all these reasons, businesses that rely on their service trucks should strongly consider investing in a fiberglass model.

How to Decide Which Type of Service Body is Right for You


Weight is an important consideration when choosing a service body. Fiberglass service bodies are typically lighter weight than their steel counterparts, making them easier to maneuver and less likely to cause damage to the vehicle they’re mounted on.

When it comes to durability, fiberglass is the clear winner. Fiberglass bodies are less likely to dent or scratch and are also resistant to corrosion.

In addition, fiberglass is a stronger material, so it can better withstand impact. As a result, a fiberglass service body will likely last longer than an aluminum body.

Corrosion Resistance

One important factor that is often overlooked is corrosion resistance. If you plan on using your truck in an environment where it will be exposed to salt, chemicals, or other corrosive materials, it is important to choose a service body that will stand up to the elements.

Aluminum is susceptible to corrosion, especially in saltwater environments.

Fiberglass offer superior corrosion resistance. Fiberglass is the way to go if you need a service body that will withstand the rigors of harsh conditions.

Safety is one of the most important factors when choosing a service body. Both aluminum and fiberglass service bodies have their unique advantages when it comes to safety. Aluminum can be more susceptible to fire than fiberglass bodies.

Fiberglass bodies are durable and resistant to corrosion. However, they have the added benefit of being flame-retardant. In addition, fiberglass is less likely to shatter in an accident. As a result, it is generally considered to be the safer choice when it comes to service bodies.


As you can see, there are many advantages of choosing a fiberglass service body over an aluminum one. Fiberglass service bodies offer superior performance in various applications thanks to their long-lasting durability, lightweight yet sturdy construction, and better insulation.

If you’re in the market for a new service body, consider a fiberglass model for all these advantages—and more!

Frequently Asked Questions

Are Aluminum Body Trucks Good?

Regarding trucks, a few different materials can be used for the body. Aluminum is one option, but fiberglass is often a better choice. There are a few reasons for this.

  1. First, aluminum is much more susceptible to damage from rocks and other debris. Fiberglass is much more durable, which will last longer and require less repair.
  2. Second, aluminum bodies can dent and distort more easily than fiberglass. This can impact the truck’s aerodynamics and cause problems with the doors and windows.

Are Fiberglass Truck Beds Good?

As any truck owner knows, the bed is one of the most important parts of the vehicle. It must be strong enough to withstand heavy loads yet lightweight enough to avoid unnecessarily affecting fuel economy.

For many truck owners, fiberglass is the material of choice for their beds. Because it’s non-conductive, fiberglass won’t corrode or rust over time as metal can.

Fiberglass is also very strong, so you don’t have to worry about your load damaging the bed.

Are Aluminum Frame Trucks Good?

Aluminum framed trucks are not as good as fiberglass framed trucks. Fiberglass is stronger than aluminum and will not dent as easily. Also, if you live in a cold climate, aluminum will crack from the cold weather. The fiberglass will not crack in cold weather.
