Transportable Prefabricated Modular Container Prefab House Ready for Quick Setup House

Walls use 50-150mm rock wool or glass wool insulated sandwich panels with thermal conductivity <=0.04W/(mK), paired with thermal-break doors and windows plus vapor barrier for year-round comfort from -20C to 45C.

Steel is non-combustible and rock wool core is A1 fire-rated. With optional intumescent fireproof coating, the building achieves 1.5-3 hour fire rating, meeting residential and public building fire codes worldwide.

Will it rust? Main structure is designed for 50+ years. Hot-dip galvanized anti-corrosion treatment exceeds 1,000 hours salt spray without red rust, delivering 30 maintenance-free years in C3 and 20+ years in C4-C5 coastal environments.

Fully-assembled modules only need crane placement and utility hookup. Flat-packed units come with detailed assembly manuals and numbered parts lists - ordinary workers with an electric wrench and basic hand tools can assemble, with our video guidance support.

Is it safe? Standard design supports 2-3 story stacking with reinforced corner posts on lower modules. Higher stacking can be specially designed. Connections use twist locks plus high-strength bolts, with full structural verification per local seismic and wind codes.
