[0002] Prefabricated buildings are structures constructed on-site using prefabricated components. Compared to traditional cast-in-place concrete buildings, prefabricated buildings utilize prefabricated and on-site assembly of key components, such as load-bearing beams, structural columns, floor slabs, wall panels, stairs, and balconies. These structures offer significant advantages, including high structural quality, rapid construction, minimal environmental impact, and low project costs.
