Deqing Residential Container House

Although there is no direct mention of specific information on residential container houses in Deqing, their technical characteristics and market applications can be summarized as follows by combining relevant cases from Tibet and other parts of China:

I. Core Structure and Materials of Container Houses Container houses use hot-dip galvanized cold-formed steel as the framework, paired with fire-resistant polyurethane or rock wool sandwich panels for walls and roofing. This structure offers rust and corrosion resistance, thermal insulation, and strong fire resistance. For example, products from Sichuan Kuaizhu Integrated Housing Co., Ltd. use Class A fire-resistant rock wool, with a core material oxygen index ≥32 and a thermal conductivity ≤0.042W/(m·K), meeting national standards. The floor is typically laid with cement fiberboard or steel-wood composite flooring, while walls and ceilings use metal panels or calcium silicate boards to ensure sound insulation and fire resistance standards are met.

II. Common Types and Suitable Scenarios

1. Packing-box Container Houses: These use a hot-dip galvanized framework with fire-resistant sandwich panels and can be used independently or stacked in multiple layers, suitable for construction site dormitories, office areas, and temporary meeting rooms. For example, products from Tibet Yuanheng Kaitai Folding Housing Co., Ltd. were used in the construction of China Mobile's earthquake relief housing.
2. Light Steel Frame Houses: These use cold-formed thin-walled light steel frames for load-bearing, with walls filled with insulation materials. The appearance and layout can be customized, making them suitable for long-term use scenarios such as cultural tourism homestays and elderly care residences.
3. Functional Supporting Houses: Such as security kiosks and eco-friendly public toilets, with flexible adjustments in size and layout to meet specific scenario needs.

III. Manufacturing Process and Quality Control The production of container houses follows a standardized process:

1. Design Phase: Complete structural design and detailed drawings based on user needs;
2. Steel Processing: Cut and weld the framework and perform surface treatment;
3. Wall Panel Composite: Fill with insulation materials and apply facing;
4. System Pre-installation: Complete pre-installation of doors, windows, electrical, plumbing, and other systems;
5. Factory Inspection: Most manufacturers conduct trial assembly to ensure component compatibility. Key quality control points include the maturity of steel structure welding processes, compliance of wall panel fire ratings, and support for customization of irregular sizes.

IV. Market Applications and Cost Advantages Container houses are widely used in temporary housing, construction site offices, cultural tourism facilities, and other fields. Their modular design supports rapid assembly, disassembly, and reuse, significantly shortening construction periods and reducing costs. For example, a water station facility in Lhasa uses a container-style design, occupying only 5 square meters and meeting the drinking water needs of 200 households, demonstrating efficient space utilization.
