Photovoltaic load-bearing detection on the roof of a factory building mainly evaluates the safety performance of the main structure of the factory building, carries out safety detection on the concrete strength and steel bar arrangement of the factory building, and provides the conclusion of load-bearing detection data. I hope my answer can help you.
