The design of stairs must meet the requirements of safety regulations, including the width and height of the steps, anti slip measures, and the stability of the railings. The step width and height of the stairs should be moderate to provide a comfortable walking experience. At the same time, the height and shape of the handrails and railings of the stairs should also comply with ergonomic principles. The design of stairs should be coordinated with the overall style of the building, while paying attention to details to enhance the overall aesthetics. The design of stairs should fully consider usage requirements, such as whether storage space, lighting facilities, etc. need to be set up.

The spiral upward design of the iron spiral staircase allows the staircase to occupy less space in the vertical direction, thereby improving the utilization of space. The smooth lines and continuous rotating movements give the iron spiral staircase a unique visual beauty, becoming the focus of interior decoration. Iron materials have high strength and hardness, which can withstand large loads and ensure the long-term safety of stairs. Iron materials have a smooth surface, are not prone to dust accumulation, and are easy to clean and maintain.
