Thickness of Exterior Wall Panels for Container Houses
The thickness of exterior wall panels for container houses varies depending on the material and purpose, with no unified standard. It can be categorized into the following three types:
Metal profiled wall panels are a common exterior wall material in container houses, typically formed by stamping cold-rolled steel plates or galvanized steel plates. Their thickness generally ranges from 0.7mm to 2.0mm, with common thicknesses including 1.0mm, 1.2mm, 1.5mm, 1.8mm, and 2.0mm. These panels are characterized by their lightweight, high strength, and corrosion resistance, making them suitable for scenarios requiring high structural strength but no special thermal insulation, such as temporary office buildings or storage facilities. The choice of thickness should consider load requirements and costs; for example, 1.0mm panels are often used in low wind pressure areas, while 2.0mm panels are suitable for coastal or high wind pressure regions.
Composite sandwich wall panels (thermal insulation panels) are composed of two metal panels with an intermediate thermal insulation core material, with a total thickness typically ranging from 50mm to 100mm, and common specifications being 50mm, 75mm, and 100mm. The core function of these panels is to provide thermal insulation, and their structure can be divided into two types: one type has an outer layer of 0.5mm color-coated steel plate or rock wool board, with an inner layer of 50mm, 75mm, or 100mm thermal insulation board (such as polystyrene or rock wool); the other type is an overall composite structure where the thickness of the two metal panels may differ, but the total thickness remains within the above range. For example, 75mm thick composite panels are widely used in cold northern regions, effectively reducing energy consumption.
Exterior wall panels for container aluminum panel building temporary houses have relatively concentrated thickness specifications, mainly 2.0mm, 2.5mm, and 3.0mm. Aluminum panels are advantageous for their strong weather resistance and good decorative properties, often used in high-end temporary houses or scenarios with high aesthetic requirements. The choice of thickness is related to the building span and wind pressure level; for example, 2.0mm aluminum panels are suitable for single-story temporary houses, while 3.0mm aluminum panels are used for multi-story or large-span structures.
It should be noted that the selection of wall panel thickness in actual projects should be comprehensively evaluated based on climate conditions, usage functions, and budget. For example, areas with high thermal insulation requirements should prioritize composite sandwich wall panels, while temporary buildings may adopt more economical metal profiled wall panels.
