Why was the elevator supported by wooden boards for a while?

The elevator is supported by wooden boards, which is a kind of protection for the elevator car before most owners formally move in (as shown below):

The surface material of elevator car is generally stainless steel plate. Before most owners formally move in, most elevators are used to transport decorative materials and furniture, so it is easy to bump against the car surface, and many dents are easy to appear on the stainless steel plate on the surface, which affects the appearance. Therefore, before most of the owners have moved in and most of the decoration has not ended, the car panel needs to be protected with plates.

Temporary plate protection, generally using a certain thickness of joinery board or density board, paint-free board, etc. Use double-sided adhesive or glass glue to adhere to the car panel.
