FAQ
Q: Does your company is a factory or trade company?
A: We are factory, so you will enjoy the best price and competitive price.
Q: Can you offer designing service?
A: Yes, we have own design engineers. We could design full solution drawings as per your requirements.

Q: Do you have stock for all items?
A: In general, we produce based on the order which we confirmed.
Q: Are container homes safe?
A: Shipping containers are as safe and reliable as traditional homes. We all know that shipping containers can transport many different types of goods over long distances and need to go through many bumpy roads. This is a strict test for shipping containers and ensures that the goods can reach the customer unscathed. This also fully demonstrates the safety and reliability of shipping containers. They can withstand many tests such as weather and natural disasters, so container houses transformed from shipping containers are also safe and reliable.
Q: Are shipping containers hot to live in?
A: In fact, if no measures are taken, the container house will indeed be very hot when used in summer. We can consider making some modifications to the interior and exterior walls of the container, such as adding insulation materials, pasting wall panels on the exterior walls, and installing air conditioners inside to ensure that the container house can provide comfort under any temperature conditions.
