A stair is a short passage that connects two floors of different heights, also called a stairway. As the city's three-dimensional and high-rise progress, such as modern times, it is indispensable in buildings, and it is an important element of architectural design in addition to its function as a passageway. In short, it is called a staircase, but there are various structures and forms, ranging from the large ones for public use to the small ones in a general house. The strong publicity must be safe and comfortable for anyone to climb up and down. This may be restricted by area or cost, but it also needs to be installed to be as safe and comfortable as possible within the allowable range.

The dimensions of the steps, the height of the stairs (the height of the riser) and the width of the tread, etc. shall be in accordance with the provisions of the Enforcement Decree of the Building Act, depending on the type and size of the building. Stairs installed on buildings with a total floor area of 200 m2 and corridors installed in the performance halls among cultural and assembly facilities shall be installed in accordance with the standards prescribed by Ordinance of the Ministry of Construction and Transportation.

Types of stairs include straight stairs, refractive stairs, hollow stairs, circular stairs, spiral stairs (extreme type of circular stairs), and the most common is straight stairs. It is a form that can be safely climbed up and down.

Materials used are various, such as wood, fiberboard, synthetic resin, iron, stone, reinforced concrete. In addition, when the height of the stairs is more than 3m, it is prescribed by law to install the landings every 3m or less or 4m or less. This is not only a resting part but also a necessary part for safety of use, and there are also regulations in the Building Code regarding its location and width. In addition, the finishing work for the installation of railings or the prevention of slipping of the tread surface is also performed in consideration of safety. If there are no walls or the like on both sides of the stairs, railings must be installed. In addition, when a slippery material is used as a stepping material for convenience of cleaning or for other reasons, a groove should be dug in the wooden stepping board, and when a metal or synthetic resin product is used, a non-slip, a rug, or a rubber rug should be laid.
