Container Mobile House Building Materials
The main building materials for container mobile houses include steel structural frames, enclosure panels, insulation materials, connectors, and sealing materials, as detailed below:
Steel Structural Frames: These are the core load-bearing structures of container mobile houses, typically made of galvanized steel or ordinary steel. For example, the products of Suzhou Zhongnan Steel Structure Co., Ltd. feature all-steel structural frames, with their packing boxes achieving a wind resistance rating of Level 12 and an earthquake resistance rating of Level 8. The frame deformation rate is only 0.18%, far below the industry's acceptable threshold of 0.3%. This frame structure not only provides sufficient strength and stability but also maintains structural integrity during multiple disassemblies and relocations.
Enclosure Panels: These include exterior and interior wall panels, commonly made of materials such as color-coated steel sheets and rock wool sandwich panels. Color-coated steel sheets offer advantages such as light weight, high strength, and easy installation, while rock wool sandwich panels provide excellent thermal insulation, heat resistance, and fire resistance. For instance, in the Jining region, due to long winters and significant temperature variations, there are high demands for condensation control on panels. Suppliers adjust the coating formulations on both sides of the panels, such as using high-weather-resistant polyester resin coatings on the exterior and adding moisture-proof aluminum foil layers on the interior to effectively reduce the probability of condensation.
Insulation Materials: These are primarily used to enhance the thermal insulation performance of the house and reduce energy consumption. Common insulation materials include rock wool, glass wool, and polystyrene foam boards. For example, companies in Hohhot that provide residential container houses commonly adopt a three-layer construction, with the middle layer filled with 80 to 100 millimeters of rock wool as the main insulation layer, reducing indoor temperature fluctuations by approximately 40% compared to traditional color-coated steel sheet houses.
Connectors and Sealing Materials: Connectors such as bolts and rivets are used to secure the steel structural frames and enclosure panels, ensuring the overall integrity of the structure. Sealing materials such as sealing strips and sealants are used to fill gaps between panels, improving the airtightness and watertightness of the house. For example, professional suppliers use CNC bending machines to control the bending angle of door frames within a tolerance of plus or minus 0.5 degrees and adopt ethylene propylene diene monomer rubber sealing strips, which offer superior weather resistance compared to ordinary silicone strips and have a service life of over five years.
