Selecting the Correct Ladder. The three most common materials used to construct ladders are wood, fibreglass, and metal (aluminium). The first consideration in determining the material from which your ladder is made is the working environment. For example, if you are working near power lines, a metal ladder should be avoided because aluminium is an electrical conductor.
Wood is one of the most commonly used materials for ladders since it is inexpensive and readily available, making it a popular choice among homeowners and small company owners. Wood is also resistant to the elements, and it will not conduct electricity and is heat resistant to a degree.
Portable ladders come in a variety of styles, the most frequent of which are stepladders, single ladders, and extension ladders, which are the three basic varieties covered in this technique. Aluminum, wood, and fibreglass are the three main materials used to construct ladders.
