Difference Between Aluminum and Fiberglass Ladders

Ladders are used to reach higher grounds for cleaning, repairing, or storage. Thus while making a ladder the manufacture has to take into calculation the weights that the ladder would be subjected to. Along with making a sturdy frame, the ladder should also be light enough to be carried and stored easily. 

Aluminum Ladders vs Fiberglass Ladders

The main difference between Aluminum and Fiberglass ladders is the strength of the ladder. Aluminum is a metal and depending on the grade, the tensile strength of Aluminum is more than that of Fiberglass. Thus in most cases, Aluminum ladders can carry more weight than Fiberglass ladders without bending or cracking.

Aluminum vs Fiberfglass ladders 1

Aluminum is a metal known for its high tensile strength, lightweight, and resistance to environmental corrosion. This is the reason why Aluminum is used in many high-performance applications, such as the manufacturing of race cars and airplanes. Thus naturally Aluminum ladders are also very strong and can good amounts of weight without getting damaged.

Fiberglass is a composite material made of glass fibers and a binding resin. It is known for its rigidity and strength, along with its resistance to environmental conditions. Thus Fiberglass does not get affected by changes in environmental conditions. As a result, ladders made of Fiberglass are typically very durable.

Comparison Table Between Aluminum and Fiberglass Ladders

Parameters of Comparison Aluminum LaddersFiberglass Ladders
Tensile Strength Aluminum ladders typically have more tensile strength  Fiberglass ladders usually have less tensile strength 
Rigidity Aluminum ladders have less rigidity Fiberglass ladders have more rigidity than aluminum ladders
Weight Aluminum ladders are comparatively lighterFiberglass ladders are heavier for the same length as aluminum ladders
Portability As aluminum ladders are light, they are more portable Due to heavier weight, fiberglass ladders are not as portable
Cost Aluminum is cheaper than fiberglass and hence aluminum ladders are also cheaper  Fiberglass ladders are typically slightly expensive than aluminum ladders

What is Aluminum ladder?

Aluminum ladders are very commonly used for indoor as well as outdoor purposes. These ladders offer more versatility and usability than wooden ladders or ladders made of other composite materials.

Aluminum is a lightweight metal known for its high tensile strength and corrosion to most environmental conditions. As a result, the ladders made of aluminum are also lighter than other types of ladders and can typically carry more weight.

As aluminum is very tensile, it does not break easily. Rather the metal bends when subjected to weight. Thus aluminum ladders do not crack easily. 

Along with being more tensile, aluminum ladders are also lighter than other types of ladders for the same height and frame size. Thus these ladders can be easily carried and stored, increasing their portability.

The only drawback of Aluminum ladders is that they can quickly get hot when placed in the sunlight. Aluminum is also a good conductor of electricity and thus it can complete a stray circuit is placed in the path of electricity.

Thus caution must be maintained when using an Aluminum ladder for performing outdoor repair work such as electrical repair, as it can lead to electrocution if the ladder comes in contact with stray charges.    

What is Fiberglass Ladder?

Fiberglass is a composite material made of glass fibers and a type of resin that binds the fibers together. The resulting material is very tough and has high rigidity. Fiberglass has many applications, including the manufacturing of sports car bodies.

Thus the ladders made of Fiberglass are also very rigid and tough. Thus they can withstand heavy loads being applied on them, without taking any damage.

Fiberglass is also completely resistant to environmental conditions such as rainwater and moisture in the air. Thus there is no chance of rusting or decaying of material in the case of fiberglass ladders.

The only drawback with fiberglass ladders is that they are heavier than Aluminum and other types of ladders. This hinders the portability of Fiberglass ladders.

Along with being heavy, they are also less tensile. Thus Fiberglass ladders do not bend underweight and crack under heavy load.

Thus while using Fiberglass ladders, the load limit that the ladder can support must be noted, as if the load is more than the limit, the ladder might crack and break.

Fiberglass is also more expensive than Aluminum. Thus fiberglass ladders of the same height and similar frame structure cost more than their Aluminum counterparts.

Main Differences Between Aluminum and Fiberglass Ladders

  1. Aluminum ladders have more tensile strength than the ladders made of Fiberglass
  2. Fiberglass ladders have more rigidity than aluminum ladders
  3. Aluminum ladders are very light weight. Fiberglass ladders are comparatively heavier than aluminum ladders
  4. As Aluminum ladders are light, they are also easy to carry and hence are very portable. Fiberglass ladders being heavy, are tough to carry around and hence are not as portable
  5. Aluminum is cheaper than Fiberglass and hence ladders made of Aluminum cost less than ladders made of fiberglass


Ladders are one of the greatest tools that mankind has ever invented. Historically ladders were made of wood, which although is a very useful material, has certain drawbacks.

Thus as scientific advancements progressed and new materials such as metals and composites were developed, stronger and more efficient tools were made to aid people in their everyday tasks.

Both Aluminum and Fiberglass ladders are examples of this advancement in technology. Aluminum ladders are made of different grades of Aluminum metal. Thus depending on the grade, these ladders have slightly varying physical properties.

Fiberglass ladders are made of the composite material known as Fiberglass. This material is made of glass fibers bound with some kind of adhesive resin. Although it is a tough material, it is not tensile and thus can break when overloaded with weight.

Both these ladders are excellent in terms of durability and lifespan, as both these materials can withstand the changes in environmental conditions without taking much damage. But in terms of portability, Aluminum ladders have an edge.
