Container Mobile House Must-See
When purchasing container mobile houses, it is essential to focus on structural types, performance indicators, compliance, and the manufacturer's service capabilities, as detailed below:
Structural Type Selection: Container mobile houses mainly come in two types: welded integral boxes and bolt-connected modular boxes. Welded boxes are formed by factory-wide welding, with direct load paths where roof loads are evenly distributed to the ground through sidewall columns and bottom beams, offering strong resistance to deformation and suitability for frequent lifting and moving scenarios. Bolt-connected modular boxes use standard panels connected by bolts, with multiple load-bearing nodes along the path. The tightness of these nodes affects overall stability. When purchasing, check the wall thickness of columns and bottom beams, with common specifications ranging from 1.5mm to 3mm. Thicker walls provide greater load-bearing redundancy but also increase self-weight.
Performance Indicator Control: Structural stability is a core safety indicator that must comply with the GB50011-2010 Building Seismic Design Code. Leading manufacturers' products can withstand wind speeds of up to 12, suitable for extreme weather conditions like typhoon seasons in coastal areas. In terms of installation efficiency, leading manufacturers' prefabricated products can be hoisted on-site in just a few hours, while non-standard white-label products require piece-by-piece assembly, taking 2-3 days per unit. For foldable container houses, transportation efficiency is crucial. Leading manufacturers' foldable boxes can reduce their volume to 1/5 of their expanded state after folding, increasing single-trip transportation capacity by over 60% and reducing transportation costs per kilometer by about 25%. Regarding fire resistance, national standards require a B1 rating or higher, while white-label products often use flammable materials, achieving only a C-level fire rating.
Compliance Review: The 2025 Ministry of Housing and Urban-Rural Development's "Safety Code for Modular Temporary Buildings" explicitly requires container houses to pass fire resistance tests and wind and earthquake resistance certifications. Export products must have international certifications such as CE and ISO. Non-standard white-label products, failing to meet compliance requirements, cannot participate in government and enterprise project tenders and may face customs seizures or certification mismatches during export.
Manufacturer Service Capability Assessment: Leading manufacturers possess full-chain service capabilities, including independent R&D and design, mass production, customization and modification, installation, operation, and maintenance. They have standardized factory areas and complete automated production lines, ensuring stable delivery efficiency, better product adaptability, and longer service life. They can also establish a nationwide service network with a response time of no more than 24 hours.
