Question 1

How is the insulation performance? Will it be cold in winter and hot in summer?

Accepted Answer

Walls use 50-150mm rock wool or glass wool insulated sandwich panels with thermal conductivity <=0.04W/(mK), paired with thermal-break doors and windows plus vapor barrier for year-round comfort from -20C to 45C.

Question 2

What about fire safety and fire rating?

Accepted Answer

Steel is non-combustible and rock wool core is A1 fire-rated. With optional intumescent fireproof coating, the building achieves 1.5-3 hour fire rating, meeting residential and public building fire codes worldwide.

Question 3

How long does a container house last?

Accepted Answer

Will it rust?	Main structure is designed for 50+ years. Hot-dip galvanized anti-corrosion treatment exceeds 1,000 hours salt spray without red rust, delivering 30 maintenance-free years in C3 and 20+ years in C4-C5 coastal environments.

Question 4

Can we install the container house ourselves? What tools are needed?

Accepted Answer

Fully-assembled modules only need crane placement and utility hookup. Flat-packed units come with detailed assembly manuals and numbered parts lists - ordinary workers with an electric wrench and basic hand tools can assemble, with our video guidance support.

Question 5

How many stories can container houses be stacked?

Accepted Answer

Is it safe?	Standard design supports 2-3 story stacking with reinforced corner posts on lower modules. Higher stacking can be specially designed. Connections use twist locks plus high-strength bolts, with full structural verification per local seismic and wind codes.

Question 6

Can container houses be expanded later?

Accepted Answer

Yes. Modular design supports lateral splicing and vertical stacking. New modules can be added on the side or stacked on top after 1-2 years, connecting to existing modules via standard twist locks and bolts without any demolition.

Question 7

Can air conditioning and fresh air systems be installed?

Accepted Answer

Yes. Walls have pre-reserved openings and outdoor unit bracket mounts for split AC quick installation on site. Fresh air ducts can run within the suspended ceiling, integrated with interior finishing for combined ventilation and temperature control.

Question 8

How is the electrical system configured?

Accepted Answer

All PVC conduits, junction boxes, distribution panel, circuit breakers, lights, switches and sockets are factory pre-installed. Simply connect to external mains power on site. Electrical systems can be customized to local voltage (110V/220V) and plug standards.

Question 9

How is waterproofing handled? Will it leak?

Accepted Answer

Roof uses single-piece bent panels without seams with 1-3% slope for drainage. Wall panels feature tongue-and-groove joints with built-in EPDM seals, and door/window frames are sealed with waterproof adhesive. Every unit passes water spray testing before delivery.

Question 10

Are you a factory or trading company? Can we visit?

Accepted Answer

We are a factory. Qingdao Yihe Steel Structure Group (EHSS), established in 2005, owns a 100,000SQ workshop with 8 production lines and 100,000-ton annual capacity. Factory visits are always welcome - we regularly host global clients for production line and showroom tours.

Question 11

What interior finishing is included?

Accepted Answer

Standard interior includes:integrated wall panels or gypsum board with paint, vinyl flooring or tiles, suspended ceiling, bathroom suite (toilet, washbasin, shower), and kitchen sink. Appliances and furniture are optional add-ons for a turnkey move-in ready solution.

Question 12

What's the minimum order quantity?

Accepted Answer

Can I buy just a few?	There is no strict MOQ. A single module can be shipped and we can arrange consolidated container sharing to reduce freight. Whether it's one sample unit or bulk camp procurement, we provide full-process service equally.

Question 13

What certifications do you have? What documents can you provide?

Accepted Answer

We hold ISO 9001 quality management certification. Products can come with CE (EN 1090-1), SGS/BV third-party test reports, EN 10204 Type 3.1 material certificates, and structural calculations. Additional certifications (GCC, SABER, etc.) can be supported upon request.

Question 14

Will container houses be damaged during sea freight? How are they packed?

Accepted Answer

Fully-assembled modules use their own structure as packaging with external protective film and internally secured furniture. Flat-packed units use steel pallets with strapping and rubber cushioning. Our long-term partnership with Maersk ensures shipping damage rate below 0.5%.

Question 15

Do container houses need local building permits? Can you assist?

Accepted Answer

Most countries require building permits. We provide structural calculations and drawings compliant with local codes (GB, AISC, Eurocode, AS/NZS), for your local registered engineer to review and stamp. The process typically takes 2-4 weeks with our full support.
