Why is the YG 20ft Expandable Container House so popular?
20ft expandable container house is gaining popularity worldwide thanks to these major advantages:
- Extremely low transportation cost: Only 2.2 meters wide when folded, matching the size of a standard 20ft container. It can be easily loaded onto flatbed trucks, container ships or trains without overlimit approval. One standard truck can carry 4–5 units at a time, cutting transportation costs by over 70% compared with traditional prefabricated houses.
- Amazing installation speed: After delivery, only 2–3 workers with simple tools can finish unloading and unfolding in 2–4 hours. All doors, windows, wiring, plumbing, cabinets, toilets and shower rooms are pre-installed before delivery, making it truly ready to use.
- High space utilization: The internal width reaches 5.56 meters when unfolded, with a usable area of about 28 square meters. Unlike the narrow, cramped space of a traditional 20ft container, expandable portable homes provide a truly comfortable living experience.
- Sturdy and durable: The main frame is welded from high-quality Q235 strip steel with high structural strength and a designed service life of more than 15 years. Wall panels are EPS sandwich panels, ensuring both strength and excellent thermal insulation.
