Special Columns for Container Houses

Special columns for container houses are typically made of steel, with common types including front columns, rear columns, and steel columns. Their specifications, materials, and processes must meet requirements for load-bearing capacity, corrosion resistance, and installation. The following provides an overview of specifications, materials and processes, application scenarios, and key purchasing considerations:

I. Specifications
The specifications of container house columns must match the overall structure. For example, the steel columns of a certain brand of packaged container-style mobile homes have dimensions of 210mm×150mm×2555mm and a wall thickness of 3mm, treated with galvanizing. The column thickness requirements for Erdos Hanjiang packaged container houses are no less than 1mm, formed through equipment pressing, with standard parts available on the market. Additionally, in container frame materials, columns are often used in conjunction with channel steel (e.g., 5×10 channel steel). Channel steel is used for welding the main crossbeams around the top and bottom, while columns serve as vertical support members, together forming the house skeleton.

II. Materials and Processes
Column materials are primarily steel, requiring high strength and corrosion resistance. National standard container frames typically use welded weathering steel (GB/T 4171), while non-box components use Q235B or Q345B steel (GB/T 700, GB/T 1591). In terms of processes, columns must undergo overall galvanizing or spray coating for corrosion resistance to extend their service life; welding processes must be full and free of cold welds to ensure structural safety. For example, columns produced by Cangzhou Xinhe Container Manufacturing Co., Ltd. support custom processing, with materials being steel containers and a fixed structure, meeting various load-bearing requirements.

III. Application Scenarios
As core support members of container houses, columns are widely used in construction site dormitories, temporary offices, commercial service buildings, and special equipment containers. Their design must consider safety during lifting, stacking, and transportation. For example, when stacking multiple containers, corner fittings and corner posts must be aligned and locked vertically, and lateral force-resisting members must be symmetrically arranged in plan and uniformly stiff vertically. Additionally, the thickness and material of columns directly affect the service life of the house, with high-quality columns enabling the house to be used for more than 10 years.

IV. Key Purchasing Considerations

1. Load-Bearing Capacity: Check the steel thickness of the main beams and columns to ensure they meet design load requirements.
2. Welding Quality: Observe whether the welds are full to avoid structural weaknesses caused by cold welds.
3. Corrosion Resistance: Prioritize columns with galvanized or spray-coated processes to prevent rust from affecting strength.
4. Specification Matching: Choose columns with appropriate specifications based on the house size and spatial combination form (e.g., single-container landing, horizontal container assembly, or vertical container stacking).
5. Supplier Qualifications: Select reputable merchants certified by the platform, such as Cangzhou Xinhe Container Manufacturing Co., Ltd., to ensure product quality and after-sales service.
