Dahuangbao Container House Manufacturing

Dahuangbao container house manufacturing typically adopts a standardized and modular production model, with core processes covering steel structure frame welding, wall and roof panel prefabrication, pre-embedding of water and electricity pipelines, and rapid on-site assembly. Product types include packing-box units, light steel keel houses, and functional kiosks, among others. The following provides an overview of the manufacturing process, product types, and key selection considerations:

Manufacturing Process

Container house manufacturing is based on standardized production lines, with core processes including:

1. Steel Structure Frame Welding: Hot-dip galvanized cold-formed steel is used as the main structural material, which is cut and welded to form the frame, followed by surface anti-rust treatment to ensure structural strength and durability.
2. Wall and Roof Panel Prefabrication: Wall panels often use rock wool, glass wool, or polyurethane sandwich panels, providing both thermal insulation and fire resistance. Roof panels must meet waterproofing requirements, with some products featuring metal or calcium silicate board cladding.
3. Pre-embedding of Water and Electricity Pipelines: The internal electrical and plumbing systems are pre-installed in the factory, reducing on-site construction steps and improving installation efficiency.
4. Trial Assembly and Transportation: Modules are trial-assembled before leaving the factory to ensure proper fit of components. During transportation, parts are disassembled into liftable units for rapid on-site assembly using bolts or clips.

Product Types

Container houses are mainly divided into three categories based on application scenarios and functional requirements:

1. Packing-Box Container Houses: These use hot-dip galvanized cold-formed steel frames paired with fire-resistant polyurethane sandwich panels. They can be used independently or stacked in multiple layers, suitable for construction site dormitories, office areas, and temporary meeting rooms.
2. Light Steel Keel Houses: These feature cold-formed thin-walled light steel keels for load-bearing, with walls filled with insulation materials. The appearance and layout can be customized, commonly used for self-built houses, homestays, and scenic area support facilities.
3. Functional Kiosks and Supporting Buildings: These offer flexible sizing and layout adjustments, such as security kiosks, property management kiosks, and eco-friendly public toilets, meeting specific scenario needs.

Key Selection Considerations

When choosing a container house, attention should be paid to:

• Production Capacity: Evaluate the manufacturer's maturity in steel structure processing techniques, wall panel fire ratings, and customization capabilities for irregular sizes.
• Material Quality: Prioritize the use of hot-dip galvanized steel, Class A fire-resistant wall panels, and eco-friendly flooring materials (such as cement fiber boards).
• Service Scope: Confirm whether one-stop services including design, transportation, installation, and after-sales support are provided to ensure project delivery timelines and service life.
