Our step ladders come in a variety of heights, typically ranging from 3 to 12 feet. They are also made from different materials, such as aluminium, fiberglass, and wood. Aluminium step ladders are the most common type, as they are lightweight and durable. Fiberglass step ladders are a good choice for working around electricity, as they are non-conductive. Wooden step ladders are the least common type, but they can be a good option for light-duty use.
