How Heavy is the Iron in Container Houses

The weight of iron (steel) in container houses varies depending on the type and size, commonly ranging from 800 kilograms to 3.95 tons. Here is a detailed analysis:

1. Packed Container Houses
Taking Tengfei packed container houses as an example, their overall weight is approximately 1350 kilograms. The frame is made of 2.3-3 mm thick galvanized steel, and the walls use 50-75 mm color-steel glass wool sandwich panels. These houses adopt a modular design, with steel mainly used for the frame structure, accounting for about 60%-70% of the weight, i.e., the steel weight is approximately 810-945 kilograms. The weights of packed container houses from other suppliers may vary slightly, but with similar steel thicknesses and frame structures, the weight ranges are comparable.

2. Foldable Container Houses
These houses weigh about 1265 kilograms and use rock wool or foam sandwich panel materials. Steel is mainly used for the frame and support structures, with a thickness typically of 2-3 mm. Based on the structural proportion, the steel weight is estimated to be about 700-800 kilograms, lower than that of packed container houses, mainly due to the lighter wall materials.

3. Fixed Container Houses
Fixed container houses weigh about 800 kilograms, making them the lightest among similar products. Their steel thickness may be relatively thin (1.5-2 mm), and the structure is simplified, resulting in reduced steel usage. These houses are suitable for scenarios with low load-bearing requirements, such as temporary offices or storage.

4. Standard Dry Cargo Containers (20GP/40GP)

• 20-foot dry cargo container: It has a tare weight of about 2.32 tons, with a steel thickness of 2-3 mm used for the frame, floor, and roof. Steel accounts for about 90% of the weight, i.e., approximately 2.09 tons.
• 40-foot dry cargo container: It has a tare weight of about 3.72 tons, with a similar steel thickness to the 20-foot container but a larger size, resulting in increased steel usage and a weight of about 3.35 tons.
  These containers are designed for long-distance transportation, with high-strength steel and a relatively large weight.

5. Special Containers

• 40-foot high cube container (40HC): It has a tare weight of about 3.95 tons. Due to the increased height, more steel is used, making it heavier than a standard 40-foot container.
• Refrigerated containers or open-top containers: Due to the additional insulation layer or open-top structure, the steel weight may be slightly adjusted, but the core frame is still based on standard containers.

Summary
The steel weight of container houses depends on the type, size, and structural design. Ordinary packed or foldable container houses have a steel weight ranging from 800 to 1350 kilograms, while standard transportation containers (such as 20GP/40GP) can have a steel weight of 2.32 to 3.95 tons. When choosing, it is necessary to comprehensively evaluate based on the intended use (such as living, transportation, or temporary construction) and load-bearing requirements.
