Corner Fittings for Container Mobile Houses

Admin September 16, 2026

Corner fittings for container mobile houses are key components used for connecting the frames of containers, box trucks, and quick-assembly houses. Their design, materials, and applications are all centered around structural stability and modular requirements.

1. Structural Design and Function

Corner fittings adopt a fixed container structure with external dimensions of 178×162×118 millimeters and a weight of approximately 11 kilograms. Their core design incorporates the principle of triangular stability, forming a geometrically rigid framework through the mutual support of three perpendicular planes. This structure not only enhances overall rigidity but also effectively disperses external impacts, ensuring that containers or quick-assembly houses remain resistant to deformation during transportation, stacking, or use.

During assembly, corner fittings are connected to panels via standardized bolt interfaces. For example, in containers, one corner fitting is installed at each corner, with side panels, end panels, and the base frame secured to the corner fittings with bolts to form an enclosed space. In quick-assembly houses, corner fittings serve as connection points between vertical columns and horizontal beams, enabling rapid assembly through modular design. This standardized interface design simplifies the construction process while ensuring precise alignment between different modules, improving assembly efficiency.

2. Materials and Processes

The main body of corner fittings is made of high-strength metal alloys, with some formulations incorporating elements like manganese and silicon to enhance impact resistance. For instance, manganese increases material hardness and wear resistance, while silicon helps optimize alloy fluidity and reduce casting defects. Additionally, corner fittings undergo heat treatment processes to eliminate internal stresses, preventing cracking due to stress concentration after prolonged use.

In terms of surface treatment, corner fittings typically employ anti-rust coatings or galvanization to withstand harsh environments. In salt spray tests, high-quality corner fittings can resist rusting for hundreds of hours, making them particularly suitable for coastal or high-humidity regions. This corrosion resistance extends the service life of corner fittings and reduces maintenance costs.

3. Application Scenarios

Corner fittings have a wide range of applications, covering containers, box trucks, and quick-assembly houses. In container transportation, corner fittings not only serve as connectors but also bear the load during stacking, ensuring the stability of multi-layer containers. In quick-assembly houses, the modular design of corner fittings supports rapid disassembly and assembly, meeting the needs of temporary buildings or emergency housing. Their standardized characteristics also make corner fittings essential foundational components in the logistics and construction industries.
