About YG’s 20-foot Container Houses
20-foot container houses are modular prefabricated buildings built based on the international standard 20-foot shipping container size. YG’s 20-foot container houses use a high-strength steel structure as the main frame, and the walls, doors, windows, water and electricity systems, ceilings, floors, and other complete interior decoration are prefabricated in the factory, making them fully usable independent spaces upon delivery, requiring no complex on-site construction.
YG’s 20-foot container houses differ from traditional repurposed shipping containers. They utilize a new modular customization process and are not refurbished second-hand freight containers. The overall structure is a one-piece light steel welded structure, with a neat structure, strong sealing, and a higher safety factor. They can be used independently or combined in multiple units to create various functional spaces such as offices, dormitories, shops, and guesthouses, making them a new type of building product with both temporary and semi-permanent use value.
How 20-Foot Container Houses Work
20-foot container houses completely overturn the traditional construction model of “on-site pouring and layer-by-layer construction” through factory prefabrication and on-site modular assembly. The overall operation process is divided into two core stages:
First, the factory integrated prefabrication stage. The manufacturer welds the main frame using high-strength galvanized steel according to standard dimensions, ensuring structural load-bearing capacity and stability. Simultaneously, the factory completes all processes, including wall insulation, fireproof board installation, waterproofing and sealing, pre-installation of water and electricity lines, door and window installation, and interior decoration, integrating all the necessary functional modules into a single unit, resulting in a finished building unit upon delivery.
Second, the on-site rapid assembly stage. The finished container houses are transported to the construction site by truck. Only a simple foundation needs to be leveled, and four workers can complete the hoisting, fixing, and wiring within three hours, putting the house into use. When multiple containers are combined, they are spliced and fixed using special connectors, and gaps are sealed with waterproofing to create large functional spaces. The entire structure relies on a steel frame for load-bearing and is modularly assembled, eliminating the need for concrete pouring. It achieves stable use through physical fixing and sealing processes and can be repeatedly hoisted, moved, and reused.
Key Features and Advantages of 20-Foot Container Houses
1. Rapid Construction and High Efficiency
Traditional construction projects can take months, and assembling prefabricated houses is cumbersome. In contrast, 20-foot container houses are entirely prefabricated in the factory, requiring no on-site construction. They are ready to use immediately upon arrival, with each container taking only a few hours to set up, significantly reducing construction time and perfectly suited for urgent construction and short-term projects.
2. Robust and Durable, Safe and Stable
The overall structure utilizes a thickened light steel frame, offering excellent earthquake and wind resistance, capable of withstanding gale-force winds of up to level 11 and earthquakes of magnitude 8. It is suitable for complex outdoor environments such as fields and construction sites. The surface is treated with anti-corrosion and rust prevention, making it waterproof, moisture-proof, fireproof, and heat-insulating, with a service life of over 15 years, far superior to ordinary prefabricated houses.
3. Outstanding Cost-Effectiveness and Low Overall Cost
No large amounts of building materials and labor are required for construction, resulting in no construction waste. The construction cost is only about one-third of that of traditional brick-and-mortar buildings. Furthermore, it can be repeatedly moved and reused, a one-time investment for multiple uses, completely solving the pain point of temporary buildings being a one-time investment that cannot be reused, and significantly reducing long-term usage costs.
4. Flexible and versatile, with excellent adaptability
Standard sizes offer high versatility; it can be used as a standalone unit or horizontally assembled and vertically stacked to create multi-story office buildings, staff dormitories, commercial streets, and other large-scale structures. Exterior and interior designs are customizable to meet diverse style needs, from minimalist commercial spaces to trendy cultural tourism destinations.
5. Green and environmentally friendly, low-carbon, and energy-saving
Fully industrialized prefabrication ensures zero dust and construction waste on-site, resulting in pollution-free construction. Materials are recyclable and reusable, offering excellent thermal insulation performance, effectively reducing long-term energy consumption. It meets global standards for green building and low-carbon construction, ensuring strong compliance for both export and domestic markets.
Main Application Scenarios of 20-foot Container Houses
- Engineering and Infrastructure Sector: Widely used in construction sites for highways, railways, bridges, mines, etc., serving as offices, staff dormitories, meeting rooms, and material warehouses, quickly addressing temporary office and accommodation needs on construction sites. The entire unit can be moved and reused after project completion.
- Commercial and Cultural Tourism Sector: Primarily used in trendy container shops, convenience stores, milk tea shops, scenic area guesthouses, camping stations, market stalls, etc. The modular design is stylish and novel, allowing for rapid construction and the creation of distinctive commercial streets, suitable for short-term commercial activities and lightweight cultural tourism projects.
