Huizhou Housing Container Renovation

The renovation of housing containers in Huizhou requires comprehensive consideration of multiple factors such as design, construction, materials, and after-sales service. The following analysis is carried out from three aspects: renovation process, core points, and local service resources.

I. Renovation Process and Core Points

1. Design Planning

   • Functional Positioning: Determine the internal layout according to the purpose (such as temporary accommodation, office, or shop). For example, workers' dormitories need to be equipped with bunk beds and lockers, while office spaces require separate workstations and meeting rooms.
   • Space Optimization: The standard size of a container is 6 meters × 3 meters × 2.7 meters. Space can be expanded through modular combinations or enhanced flexibility can be achieved through foldable or telescopic designs.
   • Compliance: It is necessary to comply with the 'Huizhou Temporary Building Management Regulations' to ensure structural safety, fire escape routes, and electrical safety standards, especially in response to the high wind pressure environment during Huizhou's typhoon season.

2. Material Selection

   • Main Structure: Prioritize the use of Q345B high-strength steel with a wind resistance rating of up to Level 15. Corrosion protection is achieved through epoxy zinc-rich primer and polyurethane topcoat, extending the service life to over 15 years.
   • Enclosure System: Rock wool sandwich panels are recommended for walls (fire rating A, density ≥ 120 kg/m³). The roof adopts a single-slope drainage design with a slope of ≥ 5% to prevent water accumulation.
   • Floor Treatment: PVC flooring or non-slip tiles are used, with a waterproof layer (thickness ≥ 1.5 mm) and an insulation layer (XPS extruded polystyrene board, thermal conductivity ≤ 0.03 W/m·K) applied to the base layer.

3. Construction Techniques

   • Structural Reinforcement: Stiffening ribs are welded at the corners of the container, and reinforcement frames are added around door and window openings to ensure overall rigidity.
   • Hidden Electrical and Plumbing Works: Electrical circuits are laid using BV wires in PVC conduits, with leakage protection devices installed in distribution boxes. Water supply pipes are made of PPR, while drainage pipes are UPVC, with a slope of ≥ 1%.
   • Moisture Prevention: The wall base layer is coated with waterproof paint, and ventilation louvers (area ≥ 5% of the floor area) are installed on the roof, supplemented by dehumidifiers to cope with humid weather.

II. Recommended Local Service Resources

1. Customized Services

   • Huizhou Hesheng Container Manufacturing Co., Ltd.: Provides specialized container designs such as data center containers and photovoltaic containers, supporting ISO standard production and personalized modifications.
   • Shenzhen Xishengqian Portable House Co., Ltd.: Mainly deals in container color steel houses with customizable sizes, using light steel structure frames with a service life of up to 18 years, suitable for accommodation and office scenarios.

2. Rental and Sales

   • Huizhou Deleshi Portable House Co., Ltd.: Offers a supermarket-style rental and sales service with daily rent starting at 3 yuan and a minimum rental period of 120 days, including supporting facilities such as mobile toilets and portable guard posts.
   • Falilai Integrated Housing Co., Ltd.: Mainly deals in fire-resistant containers with daily rent starting at 6 yuan, serving 151 people in the past year and covering areas such as Huicheng and Dayawan.

3. Construction and Installation

   • Xiangdada Mobile Housing (Shenzhen) Co., Ltd.: Provides a 6,000 yuan package delivery service for residential containers, supporting on-site installation in areas such as Chenjiang, Huizhou, with free design layout.
   • Huizhou Minghao Decoration: Although mainly engaged in traditional decoration, it holds a national second-level qualification and can undertake interior fine decoration projects for containers, providing closed-end contracts with no additional items.

III. Precautions

• Climate Adaptability: Huizhou has an average annual precipitation of over 1,700 mm, necessitating enhanced roof waterproofing and ground drainage designs to prevent leakage.
• Environmental Protection Requirements: Choose ENF-grade environmentally friendly panels to reduce formaldehyde emissions, complying with the 'Guangdong Provincial Regulations on Indoor Environmental Pollution Prevention and Control'.
• After-sales Guarantee: Prioritize suppliers offering a 10-year warranty and clarify maintenance response times (such as on-site arrival within 24 hours).
