This project involves an outdoor billboard owned by a renowned advertising company in Shenzhen.

Following the on-site examination, we have conducted a structural evaluation based on the actual conditions. We find that the main structure of the billboard is currently free of safety hazards; however, there are signs of rust on some steel components. We recommend that the client have the rust removed before normal use.
