As cities grow and the number of cars increases, especially with more families owning cars, the issue of car parking has become increasingly prominent. Parking lots, as the residential homes for cars, are evolving from flat parking to multi-level parking, from simple mechanical parking to computer-managed, highly automated modern multi-level parking. Steel structure multi-level parking lots will become buildings that offer strong practicality, aesthetics, and are suitable for urban environments.

Steel structure parking lots, as the name implies, are composed of steel components connected by bolts to form an intermediate corridor-style building. Their features include: tracks laid on the corridor floor, with a lift platform at the end of the corridor equipped with a shaft; the lift platform uses hydraulic jacks to elevate cars to parking spaces on different levels; the horizontal movement of the lift platform is driven by an oil motor; stable wheels are used to secure the car wheels when entering the platform, and the operation is controlled by photoelectricity.
