Folding Container House Custom OEM Z Type Flat Packed

Span, Packed Depth and Ordered Mass

Open, a custom z type folding container house measures 5,800 mm by 2,500 mm, and the pad has to carry that footprint exactly. That is about 14.5 m² of floor, with 2,430 mm of internal height, so a standing adult clears the ceiling. Folded, the pack sits 390 mm deep and stacks on a flat rack. Weight runs 1,100 kg on a standard build and 1,180 kg when the panel order gets thicker. The crane, the lorry and the pad all follow from those numbers.

Tube Sizes, Panel Skin and Core

Square tube comes in two wall thicknesses, 2.0 mm on the main beams and 1.5 mm through the cross members and braces. A 160 mm sill beam carries the floor deck. At each corner stand 100 mm posts. Hinge barrels run stainless and bolt through a 200 mm plate. Every tube end gets capped and sprayed with cold galvanizing before paint.

Chassis schedule
· 2.0 mm galvanized main beam along each long side
· 1.5 mm cross members under the floor deck
· 160 mm sill beam with a folded top lip
· 100 mm corner posts, four to a unit
· 200 mm hinge plate in stainless steel

Outside, a custom z type folding container house carries 0.28 mm colour steel, with a 0.35 mm liner facing the room. A 50 mm core sits between them, bonded across the full face with a two part adhesive. Roof panels follow the same build, and the floor deck is 15 mm board. Panel edges fold into a lip that takes a gasket. Two people carry one finished panel by hand.

Panel and deck build
· 0.28 mm steel skin on the outer face
· 0.35 mm liner on the room side
· 50 mm insulated core, bonded full face
· 15 mm floor deck under a wear sheet
· Folded edge with a rubber gasket seat

Main Board, Ceiling Lights and Sockets

Wiring runs through the panel voids and terminates at marked boxes. Inside sit a main switch, an earth leakage trip and spare ways for the circuits that will be added later on site. Lamps and sockets sit on separate circuits. Heights for every switch follow the drawing agreed at order. An outside socket and a light over the door can join the same loom.

Electrical kit
· Distribution board with spare ways
· Leakage trip on the socket ring
· Ceiling lamps on a switched circuit
· Wall sockets at drawing heights
· External light over the entry door Spare ways sit in the board for the circuits that will be added later on site, and an outside socket plus a light over the door can join the same loom.

Erection Steps and Site Labour Needs

Once the pack is on the pad, erection needs no crane. Four workers cut the banding, lift the roof frame and stand the long walls, with pins dropping into the corners behind them. Roof cams draw the seam closed. End panels slide into their channels, and the door is checked for swing. The drawing carries a crew through the next unit.

Crew hand tools
· Banding cutter and a rubber mallet
· Podger bar for the corner pins
· Spirit level for the pad
· Sealant gun and two spare nozzles
· Touch up paint in the RAL shade

Crate Packing, Export Papers and Field Use

Flat, a custom z type folding container house stacks into a 40HQ at 50 mm wall thickness. Timber cradles take each unit and film wraps the pack. For a long sea leg, desiccant bags go inside before the wrap closes. Lifting points stay clear of the film, so a crane hook can still reach them. Outside marking matches the packing list and the frame stencil.

Packing list
· Timber cradle under each corner
· Shrink film over the folded pack
· Desiccant bags inside the wrap
· Corner guards on the castings
· Packing list in a weatherproof pouch

Documents ride with a custom z type folding container house: invoice, packing list, bill of lading and certificate of origin. Mill certificates, test reports and stamped drawings can join an OEM order. At the plant, spares cover pins, roof cams, sash rollers and lock barrels. The same body takes work as an office, a spare room, a clinic bay or a staff cabin.
