Ladder Materials Matter: Fiberglass vs. Aluminum

Fiberglass vs. Aluminum Ladder

Ladders are essential in any work area. They come in two main materials; Fiberglass and Aluminum. While there are notable merits on both sides, they are most suitable in varying situations.

This article will not only give you a detailed analysis of both ladders to help you make informed decisions, but it will also educate you on the types of tasks they are best used for.  

Overview of Fiberglass ladders

Unlike Aluminum, Fiberglass origin is strictly man-made. It is made by strengthening plastic with glass fiber material. This process aimed to give the ladders a very rigid and reliable structure. Many ladder enthusiasts acknowledge fiberglass ladders as being one of the most durable products on the market. Capable of lasting over years in use if properly maintained and cared for. 

Fiberglass ladders are resistant to rot and decay like wooden ladders after being exposed to natural elements. However, experts advise that fiberglass ladders should not be left outside for long periods as they could become disfigured.

These ladders lose their coatings after being exposed to UV rays for a long period. Exposure to UV could prove fatal to your fiberglass ladder. This process is called fiber bloom. It may start as only detrimental to its look, but over time it leads to the deterioration of the integrity of the ladder structure. 

Advantages of fiberglass ladders

1. Durability 

When it comes to fiberglass ladders, the durability of the ladder is perhaps its most common selling point. These ladders can withstand dents, scratches, and peeling over a longer period than most ladders. They can also withstand heavy weights that may have caused damage to other ladders.

2. Does not lead to electrical accidents 

Many people may erroneously believe that using fiberglass ladders for any task that involves a power supply could result in electrical accidents. Well, the fact is, fiberglass ladders do not conduct electricity, and so offer you the most safety when dealing with electrical or power supply tasks. And so fiberglass ladders are most suitable to be used around power lines to mitigate the risk of shock or electrocution.

3. Flame resistant

Fiberglass ladders are capable of withstanding flames and preventing fire hazards. Also, the integrity of Fiberglass ladders does not deteriorate under intense heat. However, it is not advisable to subject these ladders to intense heat for a long period. Nonetheless, this is one reason the fire department loves the fiberglass ladders so much. 

4. Fiberglass ladders are stronger and do not bend easily

As we earlier stated, this is one of the most unique selling points of fiberglass ladders. They can withstand more weight than other ladders without bending or compromising the structure and efficiency of the whole ladder.

5. Weather-resistant 

When compared to aluminum ladders, fiberglass ladders have more resistance to the weather and other natural elements. Fiberglass ladder owners often leave their ladders out overnight and it does not cause any damage to the ladder.

Disadvantages of fiberglass ladders 

1. Weight of the ladder

This is the biggest drawback of using fiberglass ladders. The materials used in its production are heavy and dense and so result in the heavy weight of the overall ladder. Unlike aluminum ladders, fiberglass ladders are more difficult to lift and transport. This makes fiberglass ladders a little bit of a burden to either store or transport. 

2. Expensive 

The high cost of fiberglass is another major drawback to purchasing this ladder. However, if you do not mind the cost, a fiberglass ladder would be a great choice.

When should you choose a fiberglass ladder?

If you intend to work in an area close to a powerline, or around areas prone to electrical hazards, then a fiberglass ladder is a great choice. As long as you do not mind the heavier weight, this ladder will provide great value for your money.

If you also work with equipment that may produce significant heat, then you will need a fiberglass ladder that will not be structurally damaged as a result of this heat. Also, you are guaranteed to get years of excellent service as you properly maintain the ladder and keep it away from UV rays.

Strength and Reliability

When it comes to stability and reliability, fiberglass ladders stand out from the bunch. They are made with reinforced materials which give them added strength and stability. 


There are several distinct advantages fiberglass ladders possess over aluminum ladders when it comes to safety. As a result of its non-conductive and non-magnetic nature, it is often regarded as the much safer option for people working around magnets, fire, and electricity. Interestingly, some fiberglass ladders are fitted with a few aluminum components to get the best of both worlds.


Looking keenly at the ladder market, you’ll find out that fiberglass ladders sit in a wider price range. However, even at the low price point, fiberglass ladders still are typically more expensive than aluminum ladders. This is due to many reasons.

One of them is that fiberglass ladders are made with additional materials which could increase the overall cost of production. Another reason is the extra whistles and bells that make one particular model easier to use and better accepted by ladder users around the world.


The main material in fiberglass ladders is glass fibers. Fiberglass ladders are made from glass-reinforced plastic which is a polymer of a plastic matrix. This matrix is strengthened by smooth fibers of glass.

While some fiberglass ladders consist of just fiberglass, there are also other fiberglass ladders made using fiberglass stiles and standard aluminum rungs to increase the overall strength, durability, and lightweight nature of the ladder.

When we think of modern ladder materials that have stepped up to compensate for the excesses in ancient ladder materials. Unlike fiberglass, aluminum is naturally occurring in the earth’s crust, so it is easier to mine and manufacture. Most products made from aluminum are made from recycled products. 

Aluminum ladders offer users unique features that make them suitable for the workplace. A 6ft step aluminum ladder can weigh anywhere from 20lbs to 30lbs which does not constitute that much of a problem for most people.

For workers who may need to take a ladder from room to room, aluminum ladders are by far the easiest option. They also present the easiest option to store and transport from location to location.

Advantages of Aluminum ladders 

1. Easy to maintain

The most important factor that determines the longevity of ladders is maintenance. Most ladders require special, and in some cases tedious, measures to guarantee longevity. Aluminum ladders do not fall in this category. Simple things such as cleaning the aluminum ladder after use will go a long way to ensuring it lasts long.

2. Lightweight

This is perhaps the most common advantage of aluminum ladders. They are super lightweight and can be handled by one person without being too cumbersome. 

3. Resistance against rust or corrosion 

Aluminum ladders can withstand rust or corrosion if exposed to natural elements for some time. They are also very suitable to be used in moist regions that would have been a danger to ladders made with other materials. 

4. Resistant to fire
