Container House Panel Thickness

The thickness of container house panels varies depending on the panel type, usage scenario, and functional requirements, with a common thickness range of 0.3mm to 3.0mm. The following provides specific explanations based on different panel types and usage scenarios:

I. Steel Structure Frame Enclosure Panels
Traditional container houses are centered around steel structure frames, and the thickness of the enclosure panels must meet structural strength and insulation needs. For example, in the Jining region, to cope with temperatures as low as -30℃, a combination of 0.8mm thick corrugated steel plates and 100mm rock wool sandwich panels is used. This ensures basic insulation performance while enhancing wind and snow resistance through increased steel thickness. If only ordinary galvanized plates are used, condensation can easily cause dew formation on the inner walls of the container when the temperature difference between day and night exceeds 20℃, necessitating improvements through increased panel thickness or optimized anti-corrosion processes (such as overall galvanizing).

II. Color-Coated Panel Sandwich Structure Panels
Color-coated panel houses are designed with the principle of 'lightweight and high strength'. The panels typically use 0.3 to 0.6mm thick galvanized steel sheets, which are cold-formed into a base plate and filled with polystyrene or rock wool inside. This structure achieves a balance between wind resistance and insulation by combining steel plates that bear tensile stress with core materials that bear shear stress. For example, in the Baotou region, which experiences strong winds in spring and large temperature differences between day and night, a combination of 0.45mm galvanized color-coated steel plates and 100mm glass wool sandwich panels effectively buffers indoor temperature fluctuations while resisting bending moments caused by wind loads.

III. Aluminum Single Panel Decorative Panels
Container houses with aluminum single panel construction use aluminum alloy sheets as the base material, which are processed through cutting, bending, welding, and other processes before being coated with fluorocarbon paint on the surface. The thickness of these panels is typically 2.0mm, 2.5mm, or 3.0mm, making them suitable for interior and exterior wall decoration of buildings. Their advantages include a smooth and flat panel surface, high hardness, and excellent weather resistance, but they come at a higher cost and are mostly used in scenarios with high requirements for aesthetics and durability.

IV. Special Functional Panels
Some scenarios have special requirements for panel thickness. For example, the rock wool sandwich panels of residential containers can be as thick as 600mm to achieve Class A fire resistance, moisture and corrosion resistance, as well as sound and heat insulation effects; the walls of packaged container houses use 75mm thick color-coated glass wool sandwich panels, while the bottom frames use 3.0mm thick galvanized main beams to balance structural strength and lightweight requirements.
