Shanghai 3m x 4m Container Mobile House

Customized services for non-standard 3m x 4m container mobile houses are available in Shanghai. Here are the details:

Structure and Materials
This size of container mobile house adopts a high-strength steel welded frame to ensure overall structural stability. The modular design supports horizontal or vertical splicing and expansion, allowing for flexible adaptation to different site requirements. The walls and roof commonly use 50mm-100mm thick sandwich panels, with core materials such as rock wool, glass wool, or polyurethane, providing both thermal insulation and fire resistance. The outer steel plate has a thickness of 0.3mm-0.6mm, offering basic protection. The floor uses 15mm-18mm thick cement fiberboard or bamboo plywood as the base layer, with PVC flooring or tiles laid on the surface to meet moisture-proof and wear-resistant requirements.

Functional Configuration
The functional systems are highly customizable, including electrical systems (lighting, sockets, distribution boxes), water supply and drainage systems (reserved pipe interfaces), ventilation and air conditioning systems (optional split-type air conditioners or exhaust fans), and door and window systems (standard steel doors, aluminum alloy windows, or thermal-break aluminum windows). All configurations must comply with national standards such as the "Metal-faced Thermal Insulation Sandwich Panels for Buildings" (GB/T 23932) to ensure safety and compliance. For example, the combustion performance of sandwich panels must reach Class A (non-combustible) or Class B1 (fire-resistant), and electrical wiring must be protected with flame-retardant sleeves.

Price Reference
A manufacturer offers a wholesale price of 9,800 yuan per unit (minimum order quantity ≥ 1 unit) for a 3m x 4m iron sheet warehouse mobile toolbox (which can be regarded as a basic container house). However, the actual price is influenced by multiple factors:

• Material Differences: The type of sandwich panel core material (e.g., polyurethane is more expensive than rock wool) and the thickness of the outer steel plate (0.6mm is more expensive than 0.3mm) directly affect costs.
• Process Requirements: Upgrades in welding precision, anti-corrosion treatment (e.g., spraying epoxy zinc-rich primer), and other processes will increase costs.
• Configuration Complexity: Adding customized features such as air conditioning or independent bathrooms requires additional fees.
  It is recommended to contact 3-5 local manufacturers to obtain detailed quotations and clarify material brands, process standards, and after-sales service terms.
