Timber or wooden stairs are generally used for residential buildings because of its light weight and less usage. Further, this is preferred in areas where abundant wood is available. They are easy to construct and maintain. But they are liable to fire accidents. Timber should be free of fungal decay, insect attacks and other defects.
A typical detail of a wooden stair is shown in Fig. 21.9.
Straight flight stairs, half-turn stairs and open-well stairs may be constructed of wood.
