Container House Partition Thickness

The thickness of container house partitions typically ranges from 50mm to 100mm, depending on the material type and design requirements. The following analysis is conducted from three aspects: material type, design requirements, and structural characteristics:

1. Material Type Affects Thickness
Container house partitions are made from various materials, commonly including color-steel glass wool sandwich panels, rock wool sandwich panels, polyurethane sandwich panels, and light steel keel partitions. Among them, color-steel glass wool sandwich panels are widely used, with a standard thickness of 75mm (0.45mm color-steel sheets on both sides, filled with glass wool in the middle). Some projects may adopt 50mm or 100mm thickness to balance cost and performance. Rock wool sandwich panels, known for their excellent fire resistance, usually have a thickness ranging from 50mm to 100mm; polyurethane sandwich panels, renowned for their thermal insulation properties, typically have a thickness of 50mm to 80mm. Light steel keel partitions, as non-load-bearing structures, have a thickness determined by the keel spacing and covering materials, generally ranging from 75mm to 120mm, with a 20mm deformation space reserved to cope with container bending stress.

2. Design Requirements Determine Thickness Selection
Partition thickness needs to be adjusted according to functional requirements. For example, office areas or dormitories requiring high sound insulation may choose 100mm-thick rock wool sandwich panels; while temporary, low-cost projects may adopt 50mm-thick color-steel sheets. Additionally, partition thickness is also related to the container combination method: double-layer or row-connected container houses need to enhance overall stability by thickening partitions (such as 100mm sandwich panels) and incorporating waterproof node treatment techniques to prevent leakage.

3. Structural Characteristics Limit Thickness Range
Container houses are centered around steel structural frames, and partitions, as non-load-bearing structures, need to adapt to frame size limitations. The standard container has an internal net height of approximately 2.3m to 2.6m, and excessively thick partitions may compress usable space. Therefore, in practical engineering, partition thickness usually does not exceed 100mm, and lightweight materials (such as glass wool, polyurethane) are used to reduce self-weight and avoid imposing additional loads on the frame.
