Here is a brief guide on ladders. The quite versatile ladder is the rigid ladder, and it’s often used for many tasks. There are many kinds of rigid ladders, from the fixed type to the roof ladder type. The most basic of these is the fixed ladder; it has no moving parts. Extension ladders are composed of two ladders where one nests in the other for easy storage. The ones that form an inverted V are called step ladders. If you need space to place things like paint cans, you might need a platform ladder, which has a platform at the top. Roof ladders have hooks that set them firmly hooked on the roof. The preferred material for many ladders, except those used in electrical work is aluminium.
