Whether in residential, commercial, or public buildings, stairs are a vertical passage structure that we often come into contact with in our daily lives. Its three basic components - steps, steps, and handrails - provide users with a safe and comfortable upstairs and downstairs experience.

What are the three parts of a stair

Stair steps: Steps are the part of the stairs where users place their feet, and also the area where users step on when going up and down stairs. It is usually a horizontal rectangular platform, and its length and width can be determined based on design requirements and space size. The surface of the step should be smooth and non slip to provide good foot support. When designing, the height and depth of the steps should be determined based on ergonomic principles to provide a comfortable walking experience.

Stair step: A step is a part that connects steps of different heights and is also a vertical component of a staircase. Each step has a certain height and depth to help users achieve a smooth transition between different levels. The height of a step is generally determined by the height of the floor, and the depth of the step is determined based on the size of the step and the ergonomic needs of the user's walking. Reasonable step height and depth can reduce the pressure and discomfort of users when going up and down stairs.

Stair handrail: A handrail is a part of a staircase used to provide additional support and safety. Handrails are usually located on one or both sides of stairs, allowing users to grip and support their bodies during the process of going up and down stairs. Its height and materials should be determined according to applicable building codes and user needs. The design of the armrest should be reasonable, with a smooth surface and comfortable feel, to facilitate user use and provide additional stability and safety.

Overall, stairs consist of three basic parts: steps, steps, and handrails. These parts work together to form the basic structure of the staircase, allowing users to easily and safely go up and down the stairs. When designing stairs, it is necessary to ensure the comfort and safety of steps, steps, and handrails based on appropriate dimensions and ergonomic principles, in order to provide the best user experience.
