Ladders A Brief Guide
If you need to get a ladders 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. For many tasks, the rigid ladder is the type often used. Rigid ladders come in many varieties, from the fixed to the roof ladders. The fixed ladder is the simplest of these and 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 the top, and often forming an inverted V, are step ladders. A platform step ladder has, because of its name, a platform at the top. If you need to climb up the roof or do some outdoor house painting, you need a roof ladder, which has a hook at the top, for easy latching on the roof. Aluminium is the preferred material for ladders, except those used for electrical work, for which fibreglass ladders are used.
