What Is a Fiberglass Tonneau Cover?

Tonneau covers made from fiberglass-reinforced polymer have two things in common: strong and lightweight. Fiberglass tonneau covers are the ones whose top surfaces are made of fiberglass instead of other material such as aluminum.  

Fiberglass reinforced polymer is a composite plastic that is reinforced or supported with fibers that enhance strength. The reinforced fibers also make fiberglass tonneau covers durable. 

Fiberglass tonneau covers are typically lightweight but not as light as ABS tonneaus. They are lightweight because FRP composites have a low gravitational pull compared to metals such as aluminum. In simple logic, when something has low gravity, it has a low weight. 

Fiberglass tonneau covers are non-corrosive because FRP itself can withstand very strong elements such as acids and high temperatures. Therefore, you can rest assured that your fiberglass tonneau cover will not corrode at the exposure of strong elements including high temperatures.  

Fiberglass tonneau covers also belong to the hard folding type of tonneau covers


  • Strong and durable
  • Lightweight
  • Non-corrosive
  • Scratch and dent resistance


  • Can be pricier than other tonneau covers

What are the Available Options of Fiberglass Tonneau Covers?

Three fiberglass tonneau covers are available for purchase at PartCatalog: BAKFlip FiberMax, BAKFlip F1, and Extang Encore tonneau covers. 

So, if you are only interested in a BAK tonneau cover, BAKFlip FiberMax and BAKFlip F1 tonneau covers will meet your checklist. But if you want an Extang tonneau cover, then the Extang Encore is your best option.

A unique feature of the BAKFlip F1 is the ‘invisibility’ of attachment on the truck bed. This gives it a ‘no-profile’ aerodynamic fit since it fits perfectly and unnoticeably on the truck bed as below:

  • Fiberglass top panel
  • Made of aluminum
  • Standard foam core with carrying capacity of up to 300Lbs

Similar to other BAK tonneau covers, it gives you full bed access when it fully folds up. But you can still carry your cargo when you fold it once or twice, depending on what you want to carry.

It is also compatible with the BAKBox 2 truck toolbox and has a 3-year warranty on material and workmanship.

What are the Benefits of Fiberglass Tonneau Covers?

Fiberglass tonneau covers feature benefits common in all tonneau covers such as keeping your cargo secure from thieves and elements, improving fuel economy, and improving your truck’s looks.

But there are some benefits that are specific to fiberglass truck bed covers that should give you every reason to buy one today. These benefits include:

They are Lightweight

Fiberglass reinforced polymer is a light composite which also makes the tonneau covers lightweight. A lightweight tonneau cover makes installation a breeze since you will not worry about lifting a heavy tonneau cover if you are alone.

They weigh between 50 lbs to 100 lbs, which is lighter than their aluminum counterparts. 

They are Dent, Ding, and UV Resistant

Fiberglass reinforced polymer is structurally stiff and non-corrosive. This makes the tonneau covers dent and ding resistant.

They are also UV resistant because FRP in itself can withstand extreme heat without warps or cracks. 

Your truck bed cover will retain its new look if you buy a fiberglass tonneau cover. 

They are Stylish

Style meets function and quality with a fiberglass tonneau cover. From a matte black finish in an Extang EnCore to a high gloss textured finish in a BAKFlip F1, your vehicle will have the classy look it deserves.
