Filling the Fireproof Board & Foaming Treatment
The interior is filled with high-performance Cyclopentane Polyurethane (CPPU) insulation board,
which is flame-retardant, heat and sound insulated, heat preservedated, waterproof and airtight after getting foaming. The thickness of insulation layer could be about 50-80 mm.
Standard Earthquake-resistant Structure
Precision grinding followed by a triple-layer anti-rust coating forms a dense protective barrier over every weld. This treatment dramatically boosts corrosion resistance and service life, keeping the structure steady in marine, desert, and high-humidity climates.
Energy-saving Insulation Control System

Delivers a 24/7 supply of fresh outdoor air even with windows closed, while its multi-stage filtration removes harmful gases, prevents mold, and eliminates odors to keep the indoor environment clean and healthy.
Smart and Stylish Exterior Design
All models use fluorocarbon-coated aluminum shells that resist weather, corrosion, acid rain, and UV rays—perfect for harsh conditions. The ivory-white finish has a 75% matte effect, avoiding the dullness of full matte and the harshness of pure white, so the cabin blends naturally into the environment. The coating keeps its color for up to 20 years without fading.
