Installation video

Folding Steel Frame

Our container house frame is built of 1.5mm thick steel with full continuous welding at every connection.
Different from weak spot welding, full weld construction greatly improves structural strength for hoisting and stacking.
Finished with electrostatic powder spraying, the steel surface gets stable anti-rust & anti-corrosion protection, suitable for outdoor all-weather application.

Key features:· Hot-dip galvanized steel· High mechanical strength·Corrosion protection· High structural stability· Estimated service life ofmore than 30 years

Steel Structural Profiles

Our custom interlocking steel profile features a special concave-convex buckle structure with patented design. The interlocking seam forms an effective waterproof barrier, stopping rainwater infiltration at the joint. Compared with ordinary profiles on the market, its structural strength is increased by 30%. With a galvanized coating 20% thicker than standard options, it delivers stronger anti-corrosion performance and longer service life. Perfect for expandable and foldable container house frames, reliable for all outdoor weather conditions.

Safety & Quality

We offer multiple filling options, including rock wool, EPS and polyurethane.
The top-grade filling material achieves Class A fire resistance.
All types have passed environmental tests and comply with E0 standard, an internationally recognized low-emission grade.
It features lightweight, thermal insulation and sound insulation performance.
Suitable for extreme operating temperatures from -30°C to +70°C.

Fully Sealed Waterproof Joints

All panel joints are fully sealed with waterproof adhesive to form a continuous, tight bond.
The specially formulated adhesive is designed for outdoor exposure, delivering long-term water resistance.
It protects against corrosion, prevents water ingress, and resists impact from external debris.
With a 15-year maintenance-free service life, the waterproof seal remains stable under harsh weather conditions.

Transportation

Our foldable container house is engineered for convenient transportation and rapid assembly.
It is shipped in a folded state.
Backed by extensive international logistics experience, we can deliver our products to 90% of countries worldwide.
The foldable design cuts shipping costs and streamlines transport arrangements.
Key components are protected with cushion packaging to prevent damage during transit.
Once positioned on site, the unit can be unfolded and installed quickly.

304 Stainless Steel Welded Hinges

Our scissor folding design brings great portability and ultra-fast on-site installation.
Hinges are made of 304 stainless steel with full continuous welding.
Solid structure and reliable corrosion resistance for long-term outdoor service.

Application Scenarios

FAQ

Why do many low-cost expandable houses leak on the roof?

Leakage is mostly caused by the absence of drainage channels, thin panels and single-layer sealing. Our units come with built-in drainage channels, multi-layer UV-resistant waterproof sealant and undergo water spray testing before delivery.
What is the difference between your floor base and those thin low-cost alternatives?

Low-cost options use extremely thin floor steel plates that deform easily. We adopt thickened hot-dip galvanized floor frames with sealed panels to eliminate gaps for better waterproofing and load-bearing performance.
Some units have their roofs blown off by strong winds in the first winter. How wind-resistant are yours?

The roof adopts structural locking design instead of relying solely on sealant. We can provide wind / typhoon resistance test reports.
How long does installation actually take? Many buyers report it takes workers 7–10 hours.

Our version comes with pre-aligned components. Long installation times are usually caused by poor-quality products with misaligned holes and mismatched accessories. We supply drawings and instructional videos. For large projects, we can arrange an engineering team for on-site installation.
Why can some panels be bent by hand?

Manufacturers reduce steel thickness to cut costs. Our steel meets specified thickness standards and cannot be bent by hand under normal force.
How do you avoid misaligned screw holes and slipping self-tapping screws on thin sheets?

All holes are CNC pre-punched for consistent alignment, and thicker base material prevents screws from slipping.
Sharp sheet metal edges may cause cuts. Do you handle this?

All edges are deburred and finished before shipment.
Why can many doors still not close or lock properly after leveling?

This stems from deformed frames and warped panels. Our frames are welded and calibrated with jigs, and door frames are pre-installed and inspected at the factory.
Why can many doors still not close or lock properly after leveling?

This stems from deformed frames and warped panels. Our frames are welded and calibrated with jigs, and door frames are pre-installed and inspected at the factory.
What if the goods arrive dented, with missing screws or wrong parts?

Full inspection is carried out before shipment, and hardware is packed separately after counting. We guarantee replacement of defective parts as stipulated in the contract.
The structure becomes loose after assembly and screws work loose over time. How do you prevent this?

Lock washers and lock nuts are fitted at all key structural joints.
What causes warped panels that push doors out of alignment?

Thin steel plates deform easily with temperature changes. Thickened galvanized panels plus frame bracing reduce warping.
The pictures look premium but the actual product feels cheap. Will this happen with you?

This issue usually happens when middlemen use renderings but ship downgraded products. We are the direct manufacturer. We provide real production videos and support factory inspection via live stream.
Assembly manuals from many suppliers are hard to understand. What materials do you provide?

We supply high-definition step-by-step illustrated manuals and assembly videos. Engineers offer online support during installation. On-site technical service is available for large orders.
Why does the interior space feel much smaller than shown in pictures?

Renderings often ignore the thickness of frames and wall panels. We clearly state the internal usable dimensions in quotations, not only the outer dimensions.
Are dimensions overstated, with the actual size much smaller than advertised?

Both outer and internal dimensions are truthfully stated and written into the contract, with no exaggeration.
I am worried about insufficient insulation and condensation on inner walls in cold regions.

We use Class A fire-rated insulation material together with a vapor barrier design to prevent condensation at low temperatures, suitable for cold areas down to -30°C.
Are you a real factory or just an Alibaba reseller? Is your supply chain transparent?

We own a 50,000 m² factory in Guangzhou. On-site factory visits and live-stream production viewing are available, and our supply chain is traceable.
How is your after-sales service? Many sellers stop replying and refuse to send replacement parts after delivery.

We have formal after-sales terms. Spare parts for factory defects will be sent as agreed. We maintain communication after delivery. Since we are the factory, you can even communicate directly with our management.
Steel structures tend to rust and bring high long-term maintenance costs.

We adopt full hot-dip galvanizing plus anti-rust baking coating. Compared with ordinary spray-painted products, it delivers much better rust resistance and greatly lowers maintenance costs.
What is the service life of the waterproof sealant and the whole structure?

Our dedicated UV-resistant waterproof sealant can last up to 30 years. Our patented waterproof design, paired with galvanized steel structure, ensures a long service life with routine maintenance.
