Recently, due to the complicated form work of RC concrete (Reinforced Concrete) stairs, the risk of work paths due to the installation of copper bars, and the increase of labor costs of field workers, the site-based reinforced concrete structure of the existing wet method is not installed in the factory. Various staircase structures such as steel structure staircases that are manufactured and assembled on site are being introduced in Korea, and their application is expanding.

Such a system steel structure stair has many advantages such as workability and safety, and utility as a temporary design group. However, the system steel structure staircase inevitably includes a wet process as a subsequent process, such as filling and finishing the mortar on the stepping step to exhibit the same level of noise and vibration performance as the existing reinforced concrete structure staircase. Wet process has a problem that can lead to a decrease in workability and an increase in construction costs.
