Welded Chassis, Panel Core and Roof Sheet
Welded tube forms the chassis, with a continuous bead at every node instead of corner tacks. Columns stand at the four corners and take the lift load as well as the stack above them. Hinges run the full height of each long wall. Each hinge rides a stainless pin, and paint seals the galvanized tube so a joint knocked on site cannot start rusting through.

Sandwich board makes the walls of the 20ft x type folding container house, steel skin on both faces with an insulating core between them. The roof repeats that build and adds a profiled sheet that turns rain away from the fold line. Underfoot, a board deck with a wear layer goes down before the walls fold. Tape over every joint keeps driving rain out of the core.
