Question 1

Can you customise the flat-pack container house to our own layout and requirements?

Accepted Answer

Yes. We support both OEM and ODM projects and can fully customise dimensions, layout, partitions, doors, windows, wall panels and interior fittings. Our technical team of about 30 engineers, with 30 years of experience, can issue drawings within two hours of receiving your requirement. Sanitary units, cabinets, wardrobes and lighting can be pre-installed in the factory before shipment. Send us your drawing or requirement list and we will confirm the solution together with the quotation.

Question 2

Are you a manufacturer or a trading company?

Accepted Answer

We are a manufacturer, not a trading company. Zhongyu Group was founded in 1995 and operates a production base of over 300 mu, about 200,000 square metres, in Weifang, Shandong, through four wholly-owned subsidiaries. Our annual capacity reaches 50,000 units, and we run our own steel structure, panel and fitting production lines. Because we are factory direct, quality issues are handled by the same team that builds the units.

Question 3

How are the units assembled on site, and what installation support do you provide?

Accepted Answer

Flat-pack container houses are shipped as separate components - top frame, bottom frame, columns, wall panels, doors and windows-and assembled on site with bolts, with no welding required. This means a local team can complete installation with hand tools and a small lifting device. We supply installation drawings, guide videos and photos, and provide online video guidance during installation. Where required, we can also arrange on-site installation service.

Question 4

How do you control quality, and what warranty period do you offer?

Accepted Answer

Every unit passes incoming material inspection, frame and welding checks and a water-tightness test before packing. The flat-pack container house is built as a single integrated box, so there are no joints between separate boxes and the risk of leakage is greatly reduced; We offer a three year warranty, while the industry norm is one year, and we provide installation guide videos and photos for reference.

Question 5

Can the design be adapted to different climate conditions?

Accepted Answer

Yes. Climate is one of the first parameters we confirm, because it determines panel thickness, insulation material and roof detailing. Wall panels are available in 50 mm, 75 mm and 100 mm thickness with rock wool, glass wool, EPS or PU filling, so the specification can match hot, humid, cold or windy conditions. For hot and dry regions we focus on reflective roofing and ventilation, while for humid or rainy areas we reinforce sealing and drainage.

Question 6

What is the service life of the container house?

Accepted Answer

Under normal outdoor use and reasonable maintenance, our flat-pack container house has a service life of 15 years or more. The structural frame is the longest lasting part, while panels, seals and surface coatings need periodic inspection and renewal. Because the house is bolted rather than welded, it can be dismantled, packed and moved to a new site, so the same unit can serve several projects in sequence.

Question 7

What applications is the flat-pack container house suitable for?

Accepted Answer

It is widely used as resort guest rooms, school classrooms and dormitories, staff accommodation, temporary hospital wards and quarantine facilities, mining and project camp housing, shops on commercial streets, hotel extensions and cultural tourism projects. Because the layout is flexible, the same structure can serve as a single office, a toilet block or a multi-unit accommodation block.

Question 8

Why should we choose your company?

Accepted Answer

We combine factory direct pricing with OEM and ODM capability, backed by a 300 mu production base, 50,000 units of annual capacity and 3,000 units held in permanent stock for fast delivery. Our references include the official Express Hotel supplier project for the World Cup Qatar 2022, and Chinese state-owned EPC contractors such as Sinosteel Group and CCTEB. Units are built with a bolted.

Question 9

What is your minimum order quantity and delivery time?

Accepted Answer

Our minimum order quantity is one unit, so you can place a trial order before committing to a larger project. We hold 3,000 flat-pack units in permanent stock, and a standard unit can leave the factory in as little as seven days. For bulk or customised orders, the lead time is confirmed according to quantity and configuration before the order is placed. Shipping time depends on the destination port.

Question 10

Do you have certifications and export experience?

Accepted Answer

Yes. We hold 58 plus domestic and international certifications, including CE and ISO 9001, and are recognised as a key enterprise in China's national building system. Our products have been delivered to 85 countries with more than 3,000 completed projects, including a 146-unit flat-pack container house camp supplied for an overseas project in Riyadh, Saudi Arabia.

Question 11

What is included in a standard flat-pack container house?

Accepted Answer

A standard unit measures 6,055 * 2,990* 2,896 mm, giving about 18.1 square metres of internal area. Each set includes the top frame, bottom frame, four columns, wall panels, a steel door, a plastic-steel sliding window, flooring and the connecting bolts. Partitions, sanitary units, cabinets and lighting can be added according to your layout.

Question 12

Can you send me your price list and confirm the cost for our project?

Accepted Answer

The unit price depends on the house type, quantity, wall panel thickness and interior configuration, so we prepare a project-specific quotation rather than a fixed price list. Please tell us the house type you need and the quantity, and we will send the matching specification together with the quotation. A higher quantity allows a more favourable unit price.

Question 13

How are the units packed, and how many can be loaded into one container?

Accepted Answer

Components are packed separately -top frame, bottom frame, columns, wall panels, doors and windows-and every accessory is wrapped in double-layer bubble film, with rollers fitted to make loading and unloading easier. The collapsed width is about 2.2 metres, which stays within road transport limits and allows the units to be loaded into a standard 40HQ sea container. Packing and loading quantities are confirmed with the quotation according to the model you select.

Question 14

What electrical components and fittings come with the unit?

Accepted Answer

Each unit is supplied with a distribution box, LED tri-proof lights, sockets and switches, plus connecting hardware such as M12 bolts, nuts, flat washers and self-drilling screws. Once you tell us the destination country, the electrical components can be matched to the local voltage and plug standard. Interior fittings such as sanitary units, cabinets and wardrobes can be pre-installed according to your layout.

Question 15

Can you handle the shipping to our project site?

Accepted Answer

Yes, we can arrange international shipping by sea or air for you. Please share the project site address so we can work out the most cost-effective shipping method and give you an accurate freight figure. Assembly on arrival is straightforward, and we provide installation drawings and video guidance for your local team.
