Aluminum ladders are inherently lighter in weight, while the fiberglass ladder is more cumbersome and more difficult to transport. Aluminum ladders weigh less, and they can be moved around easier, as it is much less of a hassle to use.
A fiberglass ladder is a stronger option, especially when you consider that they are fashioned from a more durable material. An aluminum ladder is produced from aluminum, which is a flexible metal. It can bend effortlessly if it is not made with top quality aluminum.
Heat also affects aluminum and can cause it to lose its durability. Aluminum ladders, on the other hand, do avoid corrosion and can handle tasks where water is a concern. In contrast, the fiberglass ladder is made of fiberglass or fiber fortified plastic, which uses glass fibers, allowing it to be quite durable.
