Housing building system that is formed after integrated production in factories and on-spot assembly. It has thin-walled cold-formed steel components as the basic structure, and new structural panel as the structural system that goes along with other thermal-insulation materials and decoration materials.
Product characteristics: Energy Conservation, Environmental Protection, Convenient, Shortcut, Safe, and Practical.
Lasting quality: Service life of more than 50 years;
Snow resistance: Basic snow pressure of 1.55kN/m2;
Refractory property: Different designs up to 1-4 hours ;
Seismic performance: 9 degree fortification (basic seismic acceleration 0.4g) ;
Wind resistance: Basic wind pressure of 0.85kN/m2, speed of 209km/hr;
Sound insulation value: The sound insulation of the external wall (200mm thickness) is 65dB, the Inner wall (double-sided double layer 9.5mm plasterboard, 181mm wall) sound insulation is 44dB;
Ventilation performance: Combination of natural ventilation and air supply to ensure the indoor air fresh and clean, the fresh air volume is greater than 15%;
External wall impact resistance:The concentrated impact load of 250kg;
Thermal insulation property:Thermal resistance value of 200mm thick wall is 4.24Km2 / W, its thermal insulation property is twice as high as that of 490mm thick porous block brick.
