How to cap a warehouse without a roof?

1. First, apply for capping for urban construction or property, and start construction only after approval.

2. Secondly, find a professional construction team and choose materials such as fire-proof steel plates or plastic steel plates, but pay attention to the bearing capacity of the balcony.

3. Finally, don't destroy the waterproof layer, and weld the four corners of the steel plate. Just seal the interface with glue.
