What You Should Know About Ladders
Searching for a ladder? Here’s some info to help you find the right one. For various tasks, the rigid ladder is the type often used. Rigid ladders come in many varieties – fixed, extension, step, platform step, and roof. The fixed ladder is the most plain 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. The ones that form a reverse V are called step ladders. A platform step ladder has a platform at the top. Roof ladders have hooks that set them firmly hooked on the roof. Aluminium is often the preferred material for ladders, except those used for electrical work, for which fibreglass ladders are used.
