Casa container pieghevole, direttamente dalla fabbrica, tipo Z, acciaio zincato

Steel Grades, Zinc Weights and Sill Sections

Folding posts of 1.5 mm tube carry the roof and take a fold at every move. Sill beams sit closest to ground water, so they get the heaviest zinc of any section on the frame. A 100 mm sill leaves room for the deck and the gasket. Along the hinge line, side wall frames flex each time the walls come down. Squaring happens in a jig before welding.

Frame sections
· Folding post in 1.5 mm galvanized tube
· Sill beam with the heaviest zinc coat
· Top crossbeam under the roof sheet
· Secondary beam inside the roof void
· Bottom crossbeam under the floor deck

Build starts with zinc coated tube, not painted mild steel. Zinc goes on before fabrication, so the coat wraps the full section rather than resting on the outside face alone. Where parts face ground water the zinc runs heavier, and inside the roof void a lighter coat will do. Main members carry a 1.5 mm wall. Coating weight and steel gauge together decide how long a galvanized folding container house lasts.

Roof Grid, Castings and Stainless Fasteners

Top crossbeams and secondary beams form a grid over the roof. Secondary members sit inside the void where no water can reach them, so their coat runs lighter than the rest. A 0.45 mm roof sheet spans that grid and sheds water to the gutter. Purlins stop the sheet drumming in wind. Welded as one unit, the grid lifts onto the walls.

Roof build
· Top crossbeam at each panel joint
· Secondary beam across the void
· 0.45 mm profiled roof sheet
· Ridge cap with a sealed lap
· Gutter and downpipe at the low side

Cast steel corner blocks carry a machined face that no coat can cover. Hinges run stainless because they wear against the pin at every fold, and the fasteners take the same grade. Salt air turns mixed metals into a battery. A 3 mm leaf takes the pin without ovalising it. Through the paint line the galvanized folding container house keeps its castings masked, so the machined face stays bare.

Corner and hinge parts
· Cast steel corner block, machined face
· Stainless hinge leaf and pin
· Stainless bolts through the post
· Zinc washer under each bolt head
· Sealant bead behind the casting

Weld Seams, Primers and Cut Ends

Each weld seam gets wire brushed, then a coat of zinc rich primer laid on by hand. The primer reaches the toe of every weld, where rust starts first. Cut ends take cold galvanizing before assembly. Overlap onto clean steel runs 20 mm. That closes the edge. Checks follow each step, and the frame reaches the paint line only when they pass.

Surface preparation
· Wire brush on every weld seam
· Zinc rich primer at the weld toe
· Cold galvanizing spray on cut ends
· Primer overlap onto clean steel
· Wipe down before powder coating Overlap onto clean steel runs 20 mm, and that closes the edge where water would otherwise start rust. Only when the primer and the cut ends all pass does the frame move on to the paint line.

Powder Coat Over the Galvanized Layer

Powder goes on electrostatically over the zinc layer of a galvanized folding container house, then cures in an oven at the set profile. Colour comes with it, plus a barrier against moisture. At each casting face, a 100 mm band stays masked and bare. Thickness is checked on one sample per batch. Any scratch reaching the zinc is touched up before packing.

Coating stages
· Degrease and rinse before coating
· Electrostatic powder over the zinc
· Oven cure at the set profile
· Masked faces on the castings
· Touch up pen in the RAL colour

Wall Panels, Ceiling and Door Hardware

Walls and roof of a z type folding container house take insulated sandwich panels, with a steel skin bonded to both faces. Underfoot, 15 mm board lies over galvanized joists, and a wear layer covers the deck. At each corner a 150 mm column carries the roof load down into the casting, so the panels never take that weight. Stainless screws and a gasket at the joint hold each panel. Ceiling boards hide the wiring.

Wall and floor parts
· Insulated panel with a steel skin
· Stainless screw at each fixing
· 15 mm floor deck on joists
· Wear layer over the deck
· Ceiling board with a service hatch

Before the pack closes, the steel door leaf is hung and checked. Sliding sashes carry fly screens. Every drain slot faces outward, and behind a service panel the washroom option puts a shower tray, a WC and a basin. Openings are framed before the panel is cut, so the edge stays sealed. Hardware is stainless to match the frame.

Door and window parts
· Steel door leaf with a lock bar
· Aluminium sliding sash and track
· Fly screen on each opening
· Drain slot at the sash base
· Stainless screws on all trims
