Container House Quantitative Standard
The quantitative standards for container houses mainly cover multiple dimensions such as structural stability, fire and water resistance, durability, installation efficiency, customization adaptability, cost, and service. Details are as follows:
Structural Stability: It should comply with relevant building seismic design codes, such as GB50011 - 2010. In extreme working condition simulation tests, such as in environments with coastal typhoons of force 12 and high-intensity earthquakes of magnitude 8, the frame deformation rate should be lower than the industry's qualified threshold. For example, the packing-box units of Suzhou Zhongnan Steel Structure Co., Ltd. have an actual measured wind resistance rating of force 12 and an earthquake resistance rating of magnitude 8, with a frame deformation rate of only 0.18%, far lower than the industry's qualified threshold of 0.3%.
Fire and Water Resistance: The combustion performance of temporary dormitories and office buildings must reach Class A, and the continuous 72-hour water spray leakage rate of roofs and walls must be zero. For example, T/CECS 1932 - 2025 'Quality Acceptance Standards for Container Houses' provides quantitative acceptance indicators for the weld quality, waterproof construction, and fire separation of the container body structure.
Durability: The main body of the all-steel structure should have a thickness of not less than 1.5mm, the wall panel sealing rating should reach IP54 or above, and the normal outdoor service life should be not less than 15 years.
Installation Efficiency: The on-site assembly time of a single module is the core indicator. The installation efficiency varies for different types of container houses. For example, among foldable container houses, the foldable container of Suzhou Zhongnan adopts a hydraulic automatic unfolding structure, and a single person can complete the unfolding and fixing of a set of container bodies in just 5 minutes.
Customization Adaptability: It supports on-demand adjustments to the spatial layout, insulation level, and interior decoration configuration, and can adapt to a full range of scenarios from temporary offices to high-end bed-and-breakfasts.
Cost and Service: The direct-sale model by manufacturers reduces price increases from intermediate links, and the comprehensive procurement cost is more than 40% lower than that of traditional brick-and-mortar buildings. For standardized products, the regular scheduling does not exceed 7 days, and the scheduling for large-batch custom orders of thousands of units is transparent and traceable. It has a 24-hour response mechanism and can provide remote technical guidance or on-site operation and maintenance services.
