20ft Portable Flat Pack Modular Detachable Container House Prefab Low Cost

Frame material:The main frame is constructed using 2.0-3.0 mm thickened hot-dip galvanized square tubes, employing a full-welded process combined with high-strength bolt connections, resulting in overall stiffness and stability that far exceed industry standards. The top beam features a 180 mm reinforcement section, while the bottom beam features a 160 mm reinforcement section; the columns and corner brackets are integrally formed, enabling the structure to withstand pedestrian traffic on the roof as well as external impacts, with a structural service life of ≥15 years

Outstanding cost-effectiveness: Reduces costs by over 50% compared to traditional construction methods, offering the most optimal total lifecycle cost. The standard top-and-bottom frame structure has lower unit costs, reducing expenses by 50%-70% compared to conventional brick-concrete or steel structures, while eliminating complex foundation work and saving an additional 30% on foundation costs. Factory-based prefabrication eliminates on-site wet construction, cuts labor costs by 60%, and delivers comprehensive cost advantages that significantly surpass traditional building approaches

Flexible customization: On-demand configuration to create bespoke spaces. Customizable lengths (3m-9m), widths (2.2m-3m), and heights (2.5m-4m) to accommodate specific site conditions and functional requirements
