Wenshan Container House Processing

Wenshan container house processing mainly involves design, production, installation, and after-sales service. The core processes include steel structure frame welding, wall and roof panel prefabrication, and water and electricity pipeline embedding. The product types cover packing boxes, folding boxes, light steel keel houses, etc. It is necessary to select manufacturers with technical capabilities and localized service capabilities according to needs.

I. Core Processing Procedures and Techniques Container house processing typically adopts standardized production lines, with core processes including:

1. Steel Structure Frame Welding: Using hot-dip galvanized cold-formed steel or light steel keels as frames, welding forms load-bearing structures to ensure overall stability. For example, packing-box container houses use hot-dip galvanized frames paired with fire-resistant polyurethane sandwich panels, providing thermal insulation and fire resistance.
2. Wall and Roof Panel Prefabrication: Wall and roof panels undergo composite processing in factories, filled with insulation materials (such as polyurethane, rock wool) and covered, reducing on-site wet work. The wall panels of folding container houses feature a foldable design for easy transportation and storage.
3. Water and Electricity Pipeline Embedding: Electrical and water supply and drainage systems are embedded in factories, requiring only pipeline and line connections during on-site installation, significantly shortening the construction period.
4. Trial Assembly and Quality Inspection: Trial assembly is conducted before leaving the factory to check component compatibility and ensure on-site installation efficiency. For example, Yunnan Wangjia Construction Engineering Co., Ltd. controls quality through its own factory, avoiding intermediary links and ensuring delivery stability.

II. Main Product Types and Characteristics

1. Packing-Box Container Houses: With hot-dip galvanized frames as the core, paired with fire-resistant sandwich panels, they can be used independently or stacked in multiple layers, suitable for construction site dormitories, office areas, etc.
2. Folding Container Houses: They have a stable structure with few welded parts, convenient on-site installation (operable by 2-3 people), and low transportation costs (a 6-meter vehicle can carry 6 sets), suitable for emergency housing and temporary accommodations.
3. Light Steel Keel Houses: Using cold-formed thin-walled light steel keels, walls are filled with insulation materials, and the appearance and layout can be customized, suitable for long-term use scenarios such as self-built houses and homestays.
4. Functional Sentry Boxes and Supporting Houses: Such as security sentry boxes, property sentry boxes, and environmental protection public toilets, with flexible adjustment of size and layout to meet specific functional needs.

III. Key Considerations for Selecting Manufacturers

1. Technical Capabilities: Pay attention to the manufacturer's maturity in steel structure processing techniques, the fire rating of wall panels (such as Class A fire resistance standards), and the ability to customize irregular sizes.
2. Localized Services: Prioritize manufacturers with production bases in Wenshan or Yunnan, such as Yunnan Wangjia Construction Engineering Co., Ltd., whose own factory can shorten delivery times and reduce transportation costs.
3. Qualifications and Cases: Verify enterprise qualifications (such as steel structure engineering professional contracting qualifications) and implemented cases to avoid selecting pure trading merchants.
4. After-Sales Services: Confirm whether the manufacturer provides installation guidance, maintenance, and spare parts supply services to ensure long-term worry-free use.
