Core Structure and Advantages of the Prefab Expandable House
A qualified prefab expandable house must have extreme structural resilience. We use Q235B hot-dip galvanized steel for the main frame.
- Setup Speed: 2 workers finish the task in only 15-20 minutes.
- Lifespan: The structural integrity lasts for 25-30 years.
- Wind Resistance: Capable of withstanding Grade 10 winds (approx. 100km/h).
Why Choose a Prefab Expandable House Over Traditional Timber?
For clients looking for a 40ft expandable container house for sale, the fire resistance of a metal structure is the key selling point.
