Flat Pack Container House Factory Direct Pre Assembled Steel

Forty Foot Shell and Floor Area

12,032 mm is the length of the larger flat pack container house, and the second size stretches to 12,192 mm. Floor area comes to about 18 m². The 1,970 mm door leaf fits with clearance above its frame. Each pack splits into a floor, four walls and a roof, bolted together on site.

Welded Frame and Twist Lock Casting

Corner castings weld to a frame of 1.5 mm and 1.6 mm steel, and they take ISO twist locks so stacked units lock down. Between the long sides, cross members at 600 mm centres carry the deck. Folded channel, 132 mm deep, closes the floor edge and stiffens it.

· Corner casting welded to the frame
· 1.5 mm and 1.6 mm steel sections
· Cross member at 600 mm centres
· Folded channel, 132 mm deep, at the edge
· Twist lock set for stacking

Core Thickness and Insulation Gain Over Thin Panels

Wall panels of a flat pack container house carry a 50 mm core, which lifts insulation by about 25% over a 30 mm panel. Inner skin at 0.28 mm and outer at 0.45 mm hold it flat. Overhead, the roof panel runs 100 mm thick. Cut edges close with a 15 mm trim.

Panel stack
· 50 mm core with a 0.28 mm inner skin
· 0.45 mm outer skin on the wall panel
· 100 mm roof panel for sun load
· 15 mm trim on every cut edge
· Gasket roll and sealant cartridge Cut edges close with a 15 mm trim, and the 100 mm roof panel carries the sun load that would otherwise soak through a thin sheet. The 50 mm wall core lifts insulation by about 25% over a 30 mm panel.

Factory Wiring and the Site Connection Point

Cable, switches and lamps are fitted at the plant and tested before the crate closes. Inside the door, a breaker board splits circuits for light and power. One supply cable enters on site through a sealed gland, and earthing bonds the frame to the same bar as the sockets. One cable does the site power.

Electrical parts
· Breaker board with split circuits
· Ceiling lamp, switch and socket
· Sealed gland for the supply cable
· Earth bar bonded to the frame
· Wiring diagram in the document wallet

Panels, Posts and Bolts in Sequence

Panels arrive numbered and go up in the order printed on the erection sheet. Posts bolt to the floor cassette first, then the wall panels drop into the channels. Last comes the roof panel, lifted and clamped along both edges. A pre assembled flat pack container house needs no welding, no cutting and no wet trade. Hand tools close the shell.

Fixing kit
· Bolts tagged to each panel
· Seam tape for the panel joints
· Outer corner angle
· Cartridge sealant and applicator

Pre Assembly Checks Before the Crate Closes

Every panel leaves the plant cut, drilled and finished, so the crew never trims one on site. Door frames arrive welded in, each leaf already hung. Circuits are proved at the panel. Only then does the loom get coiled into the crate, and each panel takes its number against the erection sheet.

Delivered ready to fit
· Leaf already hung on its hinges
· Loom coiled and labelled by room
· Panel numbers stencilled on the edge
· Erection sheet with the bolt order

Stacking Flat Packs Inside a Container

Flats stack with frames nested and panels laid between them, banded so nothing rests on a coated face. Strapping runs through the castings. A container takes a full set of modules when the order is packed this way. Each crate carries the unit number and the block it belongs to.

Papers and marks
· Erection sheet with the bolt order
· Wiring diagram and test record
· Customs invoice and packing list
· Unit number stencil

Canteens, Field Offices and Rural Clinics

Canteens, field offices, rural clinics and classrooms all run on the same shell. A long module gives room for a counter, tables and a service window at the far end. Because the parts are flat, the pack reaches ground a lorry cannot climb. Take it down, and the flat pack container house moves on to the next contract.
