If you want a standard expandable container house with no customization, 3–5 days may be enough. Sometimes, a factory can even finish one in a single day.
How can it be that fast?
Factories that ship large volumes often have steel frames ready, with the welding and painting already finished.
With the frames prepared, three to five workers can quickly install the electrical wiring, wall panels, doors, and windows. That's one expandable container house assembled.
But in reality, it may take a month before the house is ready for delivery.
1. Customization slows things down
Most orders involve at least some customization, and that adds work beyond the standard production process.
For example, if you choose sprayed polyurethane foam insulation, the foaming work and its production schedule may add around ten days.
2. The factory has its own production schedule
Factories usually have a queue. And in my experience, two very Chinese rules sometimes come into play:
- The boss's priority orders and the top salesperson's orders get made first.
- Whoever chases the factory hardest gets moved up the queue.
That's guanxi—the art of getting things done through relationships—in action.
So look after the salesperson you work closely with, haha. Your order volume gives them more bargaining power when they're fighting for a production slot for you.
3. Ask the factory to hold the finished house for a while
My suggestion: ask the factory whether the finished house can stay at the factory for about two weeks before shipping, especially if it was assembled in just a few days.
Why? Sealants and adhesives need time to cure properly. The exact curing time depends on the materials used, but rushing a newly assembled house straight into a container is not always a good idea.
If the sealant hasn't set properly, the moisture and vibration of ocean freight may affect the joints or sealing.
Many factories won't bring this up on their own. There are two practical reasons:
- A finished expandable house takes up a lot of factory space.
- They want to ship quickly and collect the final payment.
