            But now the cast-in staircase will not have such a problem, after the completion of the decoration period, there is no need to carry out maintenance work. But the construction period of cast-in-place concrete is longer, and the requirements for workers are higher. When pouring, we must pay attention to the connection with the original wall beam and the thickness of cast-in-place concrete. As long as these two points are well done, cast-in-place staircase has many advantages over steel staircase.
