Zigong Modular Container House

The modular container houses in Zigong are prefabricated buildings based on standard shipping containers or steel structural boxes of the same specifications. They are transformed in factories and feature sturdy structures, rapid construction, and a wide range of application scenarios.

Main Types and Characteristics

1. Cargo Container Retrofit: These are directly retrofitted from retired shipping containers, retaining their original sturdy structures and offering strong wind and earthquake resistance. However, they are relatively heavy and suitable for long-term fixed locations or wilderness campsites.
2. Brand-New Welded Container Houses (Packing Boxes): These are newly welded to standard container dimensions, with a high degree of factory pre-assembly and the ability to be hoisted as a whole. They are suitable for construction site dormitories, long-term project offices, and homestays.
3. Quick-Assembly Container Houses (Demountable): These are produced with standardized components and assembled on-site using bolts, eliminating the need for welding. They have a small transportation volume and are suitable for short-term construction sites, emergency shelters, or scenarios requiring frequent relocation.

Key Factors Determining Lifespan

1. Corrosion Protection: Galvanized steel is superior to ordinary painted steel, especially in coastal, humid, or acid rain areas where rust can significantly shorten the lifespan (by approximately 30%).
2. Foundation and Waterproofing: Placing the container directly on the ground without a cement or channel steel foundation can lead to bottom rusting. Roof ponding or leaks can accelerate damage. Proper treatment can extend the lifespan by 5 to 10 years.
3. Maintenance and Care: Timely touch-up painting after scratches, avoiding overloading or unauthorized structural modifications can ensure the long-term stability of the main steel structure, with a service life of over 10 years.

Application Scenarios

1. Temporary Construction Projects: Accounting for over 70%, including construction site dormitories, project offices, and field operation buildings (such as highway, railway, and mining projects).
2. Emergency Support: Temporary disaster relief shelters, epidemic quarantine sites, and emergency command centers.
3. Commercial and Cultural Tourism: Scenic spot homestays, campsite facilities, pop-up shops, and market stalls.
4. Other Scenarios: Rural storage, livestock guard houses, temporary factory offices, and temporary school buildings.

Selection Advice
