A step ladder is the most commonly used type of ladder. It is shaped like an inverted letter V. The basic design has rungs only on one side like a traditional ladder but still has another side to support and balance the whole thing. Since there are two sides to a step ladder some designs make use of both sides. When rungs on both sides are available, it gives more convenience to a user when doing work. There is no need to move the ladder to access a nearby area because a user will only have to climb up the other side to reach the continuing space being worked on.
Unlike a traditional ladder that needs to be angled on the wall or surface, the step ladder stands up even in the middle of the room or space. This innovation in ladders makes it efficient and more useful in place when there is no wall or steady place to hold a traditional ladder.
Stepladders come in different designs for different usage. Materials used in manufacturing this type of ladder ranges from wood, aluminum or steel. When used in industries, steel step ladders are even equipped with wheels because of the weight and designed bigger to fit the required job. A small step ladder is also available for use in the retail and merchandising industry. It is designed depending on the height requirement for certain shops and stores. It can be from a two-step or higher and can even be folded for easy storage.
The step ladder can be the most specific of all ladders, it can be custom designed to fit its purpose. It is also the most innovative ladder there is. The ladder had been designed and redesigned to meet the changing demands of the household, industrial, construction and commercial markets.
