What is the Process of Customizing Container Houses in Guangdong?

The process of customizing container houses in Guangdong mainly includes seven stages: requirement confirmation, design, material procurement, production and manufacturing, interior decoration, quality inspection, and transportation and installation. Details are as follows:

1. Requirement Confirmation
Communicate in detail with the supplier about parameters such as purpose, size specifications, material requirements, interior layout, and special functions (e.g., waterproofing, thermal insulation, seismic resistance). Clarify the usage scenario (e.g., storage, living, commercial) and compliance requirements (e.g., service life of temporary buildings). This stage typically takes 1-3 working days to complete requirement对接 (对接 can be translated as 'coordination' or 'alignment' here, but for simplicity, we'll just say 'complete requirement alignment') and preliminary plan planning. Special attention should be paid to rust prevention requirements in coastal areas of Guangdong, and transportation feasibility should be confirmed in advance for mountainous or narrow road sections.

2. Design Phase
Professional designers create engineering drawings based on requirements and produce 3D renderings for customer confirmation. The design plan needs to be revised repeatedly until it meets the requirements. An ordinary project takes about 3-10 days, while complex projects (e.g., multi-story structures or special shapes) may take more than 15 days. Some manufacturers in Guangdong support real-time preview of 3D renderings. It is recommended to confirm details before signing the contract to avoid additional items later.

3. Material Procurement
Procure steel (e.g., corrugated steel plates, steel beams), flooring (wooden or steel floors), thermal insulation materials (rock wool, polyurethane), sealing materials, and accessories according to the design plan. Ordinary materials take 5-15 days, while special materials (e.g., imported anti-corrosion coatings) or custom-made accessories have longer lead times. In coastal areas of Guangdong, it is recommended to use galvanized or epoxy resin-coated steel to prevent salt corrosion; commercial container houses should have reserved water and electricity interfaces to support the installation of air conditioners and water heaters.

4. Production and Manufacturing
Cut the steel and process it into side panels, end panels, and other components. Weld and assemble the frame structure, and perform surface painting and anti-corrosion treatment. The core process usually takes 15-30 days, depending on the specifications and complexity. Manufacturers in Guangdong may adopt modular design, dividing the house into multiple standard units to save transportation space and reduce installation difficulty.

5. Interior Decoration
Complete the electrical wiring layout, thermal insulation layer installation, and decoration. Simple storage container houses can be decorated relatively quickly (about 5 days), while living container houses with living facilities take more than 20 days. For commercial container houses in Guangdong, special attention should be paid to checking circuit insulation, waterproof performance, and the content of harmful substances such as formaldehyde to ensure compliance with environmental standards.

6. Quality Inspection
Conduct structural safety tests (e.g., load-bearing capacity, wind pressure resistance), functional verifications (e.g., waterproofing, circuit insulation), and appearance inspections on the finished product to ensure compliance with national standards and customer requirements. Manufacturers in Guangdong also test for harmful substances such as formaldehyde and provide inspection reports.

7. Transportation and Installation
Select a transportation method based on site conditions. Foldable or modular designs are required for mountainous or narrow road sections. Ensure the ground is level during installation, and reinforce bolts in coastal areas to withstand typhoons. In the Pearl River Delta region, delivery can be made on the same day within 200 kilometers. Some manufacturers offer 'turnkey' services, including transportation, installation, and commissioning.

Additional Recommendations:

• Some cities in Guangdong have service life requirements for temporary buildings (generally not exceeding 5 years). Confirm the manufacturer's qualifications before customization.
• It is recommended to choose a manufacturer that offers a 1-year warranty and pay special attention to vulnerable parts such as welds and door and window seals.
• The contract should clearly specify the steel thickness, delivery time, and after-sales terms to avoid disputes.
