Stairs are an essential part of many construction projects, from decks to interiors. It can seem daunting to think of making your own, but they’re actually made of just three main parts: stringers, treads, and risers. Stringers are diagonal 2 in × 12 in (5.1 cm × 30.5 cm) boards that support people’s weight as they walk up the stairs. Treads are the top baseboards onto which you step, and risers are placed perpendicularly under each tread. Measure and cut the stringers accurately, and the other parts will mostly fall into place.


Staircase is an important structural part in construction. It allows user to go further floors. Staircase must be constructed in proper way. Otherwise, User can not feel comfortable in using other further floors.
