3. Frame construction: Use materials such as aluminum alloy or steel to build the basic frame of the stage according to the design drawings. This step includes cutting, welding and other processes to ensure the stability and load-bearing capacity of the frame.

4. Assembly and debugging: Assemble the prepared frame components, including installing ladders, spring lower hinges, etc., to ensure that each component can operate smoothly. The height of the ladder and the height of each step are assembled according to the height of the stage to meet different usage requirements.
