Stair flight is an integral part of the staircase, which is a continuous series of steps and load-bearing beams. Reinforced concrete stair flights are used in the construction of large-panel civil buildings and auxiliary structures of industrial enterprises, as well as frame-panel buildings for various purposes. The production and construction of reinforced concrete stair flights is strictly regulated by existing standards. The number of steps in a reinforced concrete stair flight varies from 5 to 11.

The stair flight of the SFHP type is ribbed with half-platforms, 5,820 mm long, 1,200 mm wide, 1650 mm high, intended for load of 4.7 kPa.
