The durability of Shandong Remote's prefabricated houses stems from engineered material systems and protective technologies that exceed conventional construction. The primary structure utilizes hot-dip galvanized steel (275g/m² coating) with a calculated 75-year service life in C3 corrosion environments. Wall assemblies incorporate impact-resistant fiber cement sheathing and UV-stable exterior finishes that maintain appearance without repainting for 25+ years. The roofing systems feature standing seam metal panels with Class A fire ratings and hail impact resistance. All structural connections are designed for fatigue resistance with 3x safety factors against dynamic loads. The houses demonstrate proven performance in accelerated aging tests equivalent to 50 years of service, with maintenance requirements 40% lower than traditional buildings.
