The weight of a ladder will definitely vary by length and size, but aluminum ladders consistently weigh less than fiberglass ladders. [2] X Research source A 24 ft (7. 3 m) extension ladder, one of the largest ladders, can weigh up to 170 lb (77. 1 kg) when made of fiberglass, but only around 35 lb (15. 9 kg) when made of aluminum.
For example, a 24 ft (7. 3 m) aluminum ladder could cost around $280 already, but a fiberglass ladder can make that price shoot up to nearly $500.
The average life expectancy of an aluminum ladder is around 20 years. [5] X Research source They also are not as susceptible to chipping and cracking like fiberglass ladders, whose coating can also be damaged when left out in the sun.
Many fiberglass ladders have the highest durability rating of 1AA, meaning that they can carry a maximum of 375 lb (170. 1 kg). [9] X Research source
Never use an aluminum ladder when dealing with power lines or electrical wiring, as aluminum is extremely conductive and can lead to serious injury. [11] X Research source
