As a Chinese manufacturer specializing in providing high-quality modular container house to clients worldwide, GROSSE GROSSE understands that you may encounter various questions in international trade. Therefore, we have compiled this Frequently Asked Questions (FAQ) guide to help you better understand our products, services, and the entire import and export process.
Q&A on Container Products
How long do container houses last?
The main frame of GREAT GRANDE’s full range of container houses is made of high-strength galvanized steel, which offers excellent corrosion resistance. With normal use and regular maintenance, the houses can last for more than 25 years.
What is the wind resistance of the houses?
Unser high-strength container houses feature an optimized structural design, with wind resistance up to levels 10-13. This makes them ideal for use in windy coastal areas or on Pacific islands. We have successfully exported our products to many such countries.
What are the advantages of GREAT GRANDE container houses compared to other products on the market?
One of our core advantages is the convex and concave groove design at the folding points of the container house, which is our patented technology. This design provides a built-in waterproof function, eliminating the need for additional sealant. It effectively isolates wind, sand, and rainwater from the outside, completely preventing any leakage issues.
Can the roof be raised?
Yes, GREAT GRANDE supports customized container house services, and you can choose to raise the roof. If you increase the height by up to 1.3 meters using EPS material, it may affect the number of units that can be loaded into one container. However, if you switch to a colored stone tile material, they can be loaded without an issue.
Can a 40 ft house be raised and still fit into a 40HQ container?
Yes, a 40ft container house can be raised, but it requires corresponding structural reinforcement, such as strengthening the columns and ensuring a flat load-bearing structure at the bottom to guarantee the stability and safety of the house.
Container Houses Shipping & Customs Clearance
Can you deliver to my address?
If your address is in the United States, we can arrange direct door-to-door delivery for the container house, but please note that the shipping and customs fees for this service may be high. For other countries or regions, we typically ship the goods to a major port in your country. After the goods arrive at the port, you will need to find a local freight forwarding company to assist with customs clearance and subsequent transportation.
How long does shipping to my country take?
This depends on your country and the specific port. Please let us know the port you would like to ship to, and we will check the detailed container house shipping time and cost for you.
How much do I need to pay for import duties?
The import tax rates vary from country to country. You can consult with your local freight company or customs department using our container house product’s HS code 940690 to get accurate tax rate information.
Container Houses Assembly & After-Sales Service
I’m new to construction. How can I ensure I can successfully assemble the house? What kind of help can you provide if I encounter problems?
We completely understand your concerns. That’s why we have designed a complete solution to ensure you can easily assemble container house:
Modular Design & Clear Labeling: The internal components of the house, such as wires, pipes, and insulation boards, are pre-installed at the factory. You will receive several large modules rather than scattered parts. All interfaces are quick-connect or color-coded—for example, a blue water pipe connector only fits a blue socket, making operation simple.
Guidance Without Language Barriers: In addition to a comprehensive English assembly manual, we also provide a full-length, high-definition video tutorial. You can watch it in advance to assess the difficulty. The video will demonstrate every step, from unboxing to completion.
Real-Time Technical Support: If you encounter any problems during assembly, you can directly connect with our engineers via WhatsApp or WeChat for a video call. They can see your progress in real-time and provide online guidance, just like an expert standing beside you.
Spare Parts Guarantee: Each package includes an additional 5% of standard parts (such as screws and buckles) in case they are needed. If any major components are damaged during shipping, we will immediately send replacements by air freight at no cost to you, ensuring there are no delays.
I plan to place the house in a wet and cold winter climate, such as in Ireland or New Zealand. How do you guarantee that condensation will not form inside the walls?
Unlike some low-cost products that simply fill the frame with insulation cotton, our container house insulation and moisture-proof system employs a more comprehensive solution:
Continuous Thermal Bridge-Free Insulation Layer: We lay a continuous, high-performance layer of rockwool or EPS board throughout the entire interior of the container. This is like the house wearing a complete set of warm thermal underwear, completely eliminating “cold spots” and preventing condensation from forming at the source.
Efficient Drainage System: Our houses can be equipped with downspouts to effectively concentrate and drain rainwater, preventing seepage or accumulation and further enhancing moisture-proof performance.
We are confident in the quality and durability of our products and can provide you with a long-term mold-free guarantee.
If you have any other questions, please feel free to contact us. We look forward to working with you and providing you with a high-quality container house solution.
