Standard Container House Manufacturing

Standard container house manufacturing is a process of modular and industrialized building production, achieving efficient construction through factory prefabrication and on-site assembly.

I. Manufacturing Process and Industrialized Production

Container house manufacturing centers on modular units, dividing buildings into standard containers and completing main structures, plumbing, electrical systems, and interior decorations in factories. For example, a smart factory in Guangdong uses a fully automated production line with welding, assembly, and grinding robots working in tandem to produce 50 steel structural modules per day, with manufacturing precision controlled within 1-2 millimeters. A concrete MiC production line in a Shenzhen industrial park produces one module every 20 minutes, with over 70% of processes completed in the factory, shortening construction periods by more than 60% compared to traditional methods. This industrialized production model transforms on-site construction into assembly-line operations, enabling parallel advancement of multiple processes and significantly enhancing efficiency.

II. Material and Structural Design Optimization

1. Steel Selection: High-strength weathering steel (such as Q355B grade) is used, with a yield strength 30% higher than ordinary carbon steel. A self-balancing system is formed through rigid connections between corner fittings and edge beams, reducing material usage by about 15%.
2. Enclosure Structure: A three-layer composite structure of "rock wool-air layer-aluminum-zinc plate" is used, with a thermal conductivity below 0.040 W/(m·K) and a heat transfer coefficient (U-value) below 0.5 W/(m²·K), effectively coping with low-temperature environments.
3. Connection Nodes: For areas with a seismic design intensity of 7 degrees, a dual-fixing mode of "wedge lock + high-strength bolts" is adopted. The wedge lock has a bevel angle of 15 degrees, with displacement controlled within 3 millimeters in simulated 8-degree earthquakes, outperforming conventional welded nodes.

III. Performance Verification and Scenario Adaptation

Third-party practical test data shows that products from leading companies (such as Suzhou Zhongnan Steel Structure Packing Boxes) have a frame deformation rate of only 0.18% under 12-grade typhoon and 8-grade earthquake conditions, well below the industry's 0.3% pass threshold. Container houses have covered scenarios such as temporary offices, accommodations, and commercial pop-ups, with their flexible assembly characteristics meeting customized needs. For example, a pop-up store project in a Shanghai commercial district achieved an internal space utilization rate exceeding 90% through curved walls and floor-to-ceiling glass windows, and can be disassembled and reassembled more than 15 times, with the cost per use being only one-third of that of a new product.
