A Consumer’s Walkthough on Ladders
If you need a ladder for a particular task, you might want to know more about ladders in general. This might help in your choosing the right ladder for the job. The rigid ladder is usually the ladder type used for most tasks. There are many types of rigid ladders, from the fixed type to the roof ladder type. The most basic of ladder types is the fixed ladder; it has no moving parts. Extension ladders are the type that can be lengthened, since one part is nested in the other for storage. Joined by a hinge at its top, and often forming an inverted V, are step ladders. A platform step ladder has a platform at the top. Ladders that have hooks to set them locked on the roof are called roof ladders. Aluminium is the choice material for various ladders, except those for electrical work.
