The Model A Concave-Convex Beam Folding Container House is our reinforced folding unit: the same 370 mm fold-flat concept, but built on an interlocking concave-convex beam frame for greater rigidity and better frame alignment during repeated folding.
What is a concave-convex beam folding container house?
Definition: a concave-convex beam folding container house is a foldable prefabricated building whose side frames use interlocking (concave-convex) profiled beams — 60x70x1.5 mm — rather than plain square tubes. The interlocking profile locks the frames together, increasing rigidity and preventing misalignment while the unit is folded for shipping. Also known as: interlocking beam folding container, X-fold container house.
Product overview
Model A is engineered for maximum transport efficiency and rapid deployment. When unfolded it provides a 5800 x 2500 x 2420 mm room with 50 kg/m³ rock wool sandwich panel walls, an 18 mm fire-rated floor and a 20A electrical package. When folded, the unit is only 370 mm thick, so twelve sets load into one 40ft high cube container — the same ocean freight moves 12 units instead of 1.
Concave-convex beam structure
- Base frame: 40x80x2.0 mm long beams combined with 60x70x1.5 mm convex tubes; 60x80x2.0 mm galvanized short beams; 9 secondary beams and 6 supports
- Side frames: 60x70x1.5 mm concave-convex channel x 8, with dedicated folded supports and 34 stainless steel hinge shafts
- Front/rear frames: 60x40x1.5 mm P-type tubes with dedicated door-edge and threshold profiles
- Roof: 60x40x1.5 mm P-type tube frame, 30x50x1.3 mm purlins, glass wool insulation, 0.4 mm roof tile and 831 ceiling tile
The result is a stiffer folding mechanism that keeps doors, windows and panels aligned through years of repeated folding and relocation.

FAQ
What is a concave-convex beam folding container house?
A foldable prefabricated unit whose side and base frames use interlocking (concave-convex) profiled beams instead of plain square tubes. The interlocking profile raises rigidity and keeps frames aligned during folding and transport. Model A is 5800x2500x2420 mm unfolded and folds to just 370 mm thick.
How many units fit in one container?
Twelve sets load into a single 40ft high cube container when folded to 370 mm, cutting ocean freight per unit to a fraction of a fully assembled container house.
How long does it take to unfold?
10-15 minutes with 2-3 workers using basic hand tools — no crane, welding or specialist equipment.
Can it be reused and relocated?
Yes. The concave-convex beam frame with stainless steel hinge shafts lets the unit fold back to 370 mm for transport, so it can be redeployed many times over its 10-year design life.
Four Key Advantages
Fast Assembly
Pre-fabricated and modular design allows rapid on-site deployment. Most units can be assembled within 24-48 hours, minimizing labor costs and project timelines.
Cost-Effective Shipping
Optimized flat-pack design drastically reduces shipping volume. Multiple units can be loaded into a single container, saving up to 60% on international freight costs.
Built to Last
Corrosion-resistant galvanized steel frame with premium insulation. Engineered to withstand extreme weather, from scorching deserts to freezing mountains.
Stackable Design
Up to 3 stories with structural integrity. Modular connection system enables flexible expansion as your needs grow over time.
