Nantong Fast-Assembled Container House
Nantong fast-assembled container houses are modular integrated houses quickly assembled on-site using standardized components. They are widely used in scenarios such as temporary offices and workers' dormitories. The following are their core structures, selection points, and comparison dimensions:
Core Structures and Materials
The structural forms are divided into welded frames and bolt-connected frames. The welded frame has good overall rigidity, strong wind and earthquake resistance, and is suitable for long-term fixed use; the bolt-connected frame can be disassembled and assembled multiple times, with low transportation costs, and is suitable for short-term projects or those with frequent site changes. Common wall materials include color-steel sandwich panels (such as rock wool, polyurethane, and EPS foam) and light steel keel composite panels. Color-steel sandwich panels are inexpensive but have average sound insulation and heat insulation; light steel keel composite panels have a high fire rating (up to Class A), good sound insulation (sound insulation of more than 45dB), and are relatively expensive. The floor system usually uses 15mm - 18mm thick cement fiber boards or checkered steel plates. Cement fiber boards are moisture-proof and flat, suitable for living; checkered steel plates have strong load-bearing capacity and are suitable for storing heavy equipment.
Common Models and Selection Points
The economical (standard) model is mostly 3m×6m in size, with a price of about 8,000 - 15,000 yuan per set. It is quickly installed and suitable for temporary workers' dormitories or short-term offices. The comfortable (reinforced) model can be up to 4m×8m in size, with good thermal insulation performance and a service life of more than 10 years, suitable for long-term camps or project offices. The high-end (customized) model can be customized in size, with complete functions and a beautiful appearance, with a price of about 30,000 - 80,000 yuan per set, suitable for scenic spot facilities or high-demand projects.
Key Comparison Dimensions
In terms of installation speed, the economical model is the fastest, completing one building in 2 - 3 days; the comfortable model takes 5 - 7 days; the high-end model takes 7 - 15 days. In terms of service life, the economical model is about 5 - 8 years; the comfortable model is 10 - 15 years; the high-end model can reach more than 20 years. In terms of transportation costs, the freight for a single set of the economical model is about 500 - 1,000 yuan; for the high-end model, due to its large size, the freight may double. In terms of environmental adaptability, given Nantong's humid climate, it is recommended to give priority to rock wool sandwich panels or light steel keel composite panels and avoid using EPS foam panels.
The industry mainly follows relevant national standards. When purchasing, it is necessary to confirm the fire rating. For dormitories or offices, the wall materials must meet Class A or Class B1 fire standards.
