How Thick Are the Columns of Container Houses

The thickness of the columns of container houses is usually not less than 1 millimeter. Some suppliers use square steel with a thickness of 4 millimeters or 6 millimeters, and customized products can reach 2.3 millimeters or more. The specific thickness varies depending on the supplier, purpose, and design requirements. Here is a detailed analysis:

1. Basic Standards and Common Specifications
Most container house columns are made of steel with a thickness of more than 1 millimeter, which is the minimum industry standard. For example, a supplier in Inner Mongolia explicitly states that the column thickness is 'not less than 1 millimeter' and requires professional equipment for pressing. There are ready-made products available on the market. These columns, together with channel steel, form the framework and play a decisive role in the overall strength of the house.

2. Supplier Differences and Performance Optimization

• Ordinary Suppliers: To reduce costs, some use square steel with a thickness of 4 millimeters as columns. However, when stacking two layers, the bottom columns may deform due to excessive local pressure, affecting the structural stability.
• Transforming Suppliers: They upgrade materials to improve performance. For example, they use square steel with a thickness of 6 millimeters and add reinforcing ribs at the connection nodes, increasing the overall compressive strength by about 50%. Such designs are more suitable for multi-layer stacking or high-load-bearing scenarios.

3. Customized Requirements and High-end Applications
For special purposes or high-end projects, the column thickness may be further increased. For example, a professional custom manufacturer in Beijing requires the column wall thickness to be 'not less than 2.3 millimeters' and emphasizes that the frame should be fully welded to meet the requirements of the JGJ/T 435-2018 standard regarding load and anti-overturning. In addition, industrial applications such as energy storage container houses may use steel plates with a thickness of 6 millimeters and enhance local strength through complex bending processes.

4. Material Selection and Structural Safety
The column thickness is not the only key factor; material quality and welding process are also crucial. The frames of national standard container houses are usually welded from section steel. It is necessary to ensure full and solid welding without cold solder joints and undergo overall galvanizing or spraying for anti-corrosion treatment. These details determine the safety of the container house during lifting, transportation, and long-term use, directly affecting its service life (usually more than 10 years).
