Adopt upgraded structural design and high-quality materials to achieve excellent wind and earthquake resistance. The galvanized steel frame with thickened walls and integrated connection nodes enables the house to withstand 12-14 level strong winds and 8-level earthquake intensity, adapting to harsh climate conditions in various regions. The sandwich panels are filled with flame-retardant materials (such as rock wool) reaching B1 fire rating, while the galvanized surface treatment effectively prevents corrosion and moisture, ensuring structural stability and living safety even in humid or coastal environments.
