his case is an on-site acceptance photo of our foldable container houses for a power engineering project in the Saudi desert. The project adopts a two-storey row layout. Light grey cabins are equipped with external corridors, guardrails and outdoor staircases. Neat and orderly, they serve as staff dormitories and on-site offices. Each cabin has a modular foldable structure and is fully prefabricated in the factory. On-site hoisting and assembly are fast with minimal civil works, suitable for rapid setup at remote desert worksites. The wall panels are high-performance thermal insulation boards tailored for the Saudi desert environment with extreme heat, intense sunlight and blowing sand. They deliver outstanding heat insulation and sand-proof performance to block outdoor intense heat. When folded, the cabins are compact for ocean export shipping. Water and electrical pipelines are prefabricated inside, so they are ready for operation once assembled and connected. They are applicable to dormitories, project offices and auxiliary barracks for energy infrastructure projects in Saudi Arabia. Units can be stacked into multiple floors and linked together in continuous rows. The cabins can be disassembled, relocated and reused repeatedly. Jinzhong offers customized thermal insulation and dust-proof configurations for high-temperature, sandy desert environments. We provide one-stop mass production and on-site acceptance guidance. It is an ideal temporary building solution for large camps of energy projects across the Middle East.
