Zhangjiakou Factory Building Prefabrication

Zhangjiakou factory building prefabrication mainly involves prefabricated modular houses, prefabricated concrete building products, and related enterprise cases. Specific information is as follows:

I. Types of Prefabricated Modular Houses

In the Zhangjiakou region, factory building prefabrication primarily focuses on modular and lightweight structures, with common types including:

1. Container Modular Houses: Using standard containers as basic units, extended through welding or bolt connections, suitable for temporary office and accommodation scenarios, featuring rapid assembly/disassembly and high mobility.
2. Light Steel Prefabricated Houses: With lightweight steel structures as the framework and insulation panels (such as rock wool boards and polystyrene boards) as the enclosure, they have a short construction period and better seismic performance than traditional brick-concrete structures, commonly used in industrial plants and warehouse construction.
3. Prefabricated Box Houses and Color Steel Houses:
   • Prefabricated Box Houses: Combining lightweight steel structure frameworks with color steel sandwich panels (such as polyurethane core materials), they possess fire resistance, moisture resistance, and sound insulation properties, suitable for temporary construction site housing and emergency shelter.
   • Prefabricated Color Steel Houses: Including various subtypes such as hoisted, assembled, and mobile houses, using color steel plates as wall materials and assembled with bolts, they have lower costs and are mostly used for short-term projects.

II. Prefabricated Concrete Building Products

There is wholesale information on prefabricated concrete building-related products in the Zhangjiakou region, updated on December 14, 2024, involving 88 products that support online transactions. These products typically include prefabricated concrete wall panels, floor slabs, stairs, and other components, which are standardized and produced in factories before being transported to the site for assembly. This approach can shorten the construction period and reduce on-site wet operations, suitable for permanent buildings with high durability requirements.

III. Enterprise Cases and Industry References

1. Historical Enterprise Experience: Zhangjiakou Zhiyong Tong Prefabricated Housing Co., Ltd. (now deregistered) was engaged in the processing and sales of reinforced concrete prefabricated structural components, with products covering building structures, prefabricated slabs, stairs, door and window frames, etc., and also involved in landscape engineering and plastic steel door and window installation. Its business model of factory-prefabricated components + on-site assembly can provide design and production process references for current projects.
2. Double-T Slab Application Reference: Double-T slabs (prestressed concrete components) widely used in warehouse construction in the Hebei region have characteristics such as large spans (up to over 30 meters), high construction efficiency, and good durability. Although Zhangjiakou enterprises are not directly mentioned, information on double-T slab manufacturers can be obtained through industry associations, building material platforms, or industry exhibitions, indirectly supporting local prefabricated component procurement.

Summary: Zhangjiakou factory building prefabrication mainly focuses on modular structures, with materials covering steel, concrete, and composite panels. Enterprises can purchase standardized products through wholesale platforms or customize components by referring to historical enterprise experiences. For large-scale projects, the application cases of double-T slabs in the Hebei region can be used as references to optimize the supply chain through industry resources.
