20ft Folding Container House Foldable Prefab Container Home

Folded Depth, Floor Area and Clear Height

Open, the 20ft folding container house gives 14.5 m² of floor and 2265 mm of headroom under the ceiling. Folded for the road, the same body is only 390 mm deep, so a stack of shells shares one trailer slot. Four corner castings take the slings, and a yard forklift shifts the package on level ground. A crew checks the pad first.

Square Tube Columns and Stainless Hinges

Columns are 150 by 62 mm galvanized U-groove sections with a 1.5 mm wall, welded to a 160 mm sill beam. Each column top carries a cast steel block that takes the lifting load and the weight of a stack above. Wall panels turn on 304 stainless hinges of 3 mm plate, chosen because water collects along that line. Coach bolts rather than welds join one module to the next on site.

Hinge and column schedule
· 150 by 62 mm galvanized U-groove column, 1.5 mm wall
· 160 mm sill beam welded to each post foot
· Cast steel corner block at every column top
· 304 stainless hinge, 3 mm plate, two per wall
· Coach bolts and packing shims in the hardware box A cast steel block at each column top takes the lifting load, so the crane can pull a module from the stack without bending a column. Water runs off the hinge line, which is why the hinge plate is stainless rather than plain steel.

Sandwich Panels, Roof Sheet and Floor Deck

Walls take 50 mm sandwich panels, 0.28 mm steel outside and a rock wool core within. That core weighs 65 kg per cubic metre. It earns the wall Class A, and heat holds better than with a foam fill. Roofing runs 0.45 mm profiled steel over 30 mm of wool, laid across the short run of the body. Seams stay off the walk line. The floor is a 15 mm MGO deck under a 1.6 mm wear film. A ceiling panel of 0.28 mm lifts away to reach the wiring.

Sockets, Breaker and Ceiling Lighting

Wiring is pulled and tested at the plant, before the panels close for the road. Inside, the standard set is one breaker, a pair of US sockets and one 110 V outlet. Five LED lights cover a room of this size. The circuit is rated at about 1.5 kW, enough for lights, a fan and a kettle. Voltage and plug type follow the destination market, while a leakage trip guards the ring.

Rollers, Ramps and Temporary Site Housing

A folded depth of 390 mm is what pays the freight, because a stack of shells uses a fraction of built volume. No strap touches a panel, since loading runs through the four castings. Crates carry the hardware box, a key set and the wiring diagram. Rollers or a short ramp help a crew slide the package into place without a crane.

Site offices, staff rooms, security posts and small clinics all run on the same body. Camps take one unit first, then add a second as the crew grows, and each module packs to the same slab. Relief work favours the 20ft folding container house, since a batch moves on one truck. This body also serves as a canteen or a first aid room.
