This case is an on-site photo of our foldable container houses at a large construction camp in Qatar. The project adopts a two-story row layout with white cabins fitted with external staircases and guardrails. Neat and orderly, these units serve as large-scale worker dormitories and on-site offices. Each cabin features a modular foldable structure and is fully prefabricated in the factory. The units can be quickly assembled and stacked on site with minimal civil work, well suited for mass construction. The wall panels are made of thickened thermal insulation boards, specially adapted to the extreme heat of the Middle East. They deliver reliable heat insulation and dust resistance to protect the interior from intense sunlight and blowing sand. When folded, the cabins are suitable for bulk container sea shipment, greatly cutting cross-border logistics costs. Water and electrical pipelines are prefabricated inside, so they are ready for occupancy once assembled and connected. They are widely used as worker dormitories, project offices and auxiliary camp buildings for infrastructure projects in Qatar. Units can be stacked into multiple floors and arranged in continuous rows. They can be disassembled, relocated and reused after the project. Jinzhong provides custom thermal insulation and dust-proof configurations tailored for the hot, sandy climate of the Middle East. We offer one-stop mass production and on-site installation guidance. It is an ideal prefab solution for large temporary construction camps across the Middle East.
