combinhou prefab house is of thin-walled lightweight steel structure, which meets the building structural requirements (water-p 1.Prefabricated steel frame house 2.Comfortable living 3.Beautiful and practicalcombinhou prefab house is of thin-walled lightweight steel structure, which  meets the building structural requirements (water-proof and anti-corrosive). All the steel components such as trusses, beams, purlins and columns are standardized, painted and anti-rust which can be normally used for more than 20 years. Columns are bolted to the foundation and other steel components.Wall Panel: Color-coated steel sandwich panel made of double-sided steel sheets and the middle layer of expanded polystyrene (EPS) foam Steel Sheet: 0.326mm thickness, EPS foam: 100mm thickness, density: 12kg /m3. This kind of EPS  sandwich panels are heat and sound insulated. Roof Panel: Color-coated steel sandwich panel made of double-sided steel sheets and the middle layer of expanded polystyrene (EPS) foam, steel sheet: 0.326mm thickness; PU foam: 100mm thickness and density: 12kg /m3. The rain water is evacuated by rain gutter.Doors are profiled bar frames and color-coated steel sandwich boards. Windows are PVC frames with sliding glass. Doors, windows and interior partitions can be flexibly fixed. Staircases are designed outside the house.  Due to prefab houses designed and manufactured in modulus, various designs can be provided to meet customers' satisfaction. Main material specification list: As listed in the attached file “Main Material Specification for double-pitched prefabricated house”. 3. Technical Parameter Snow load capacity: 100kg/m2 External wall heat transmission coefficient: 0.35Kcal/m2hcMain skeleton(Base-plate or Floor plate Load Capacity): 200 kg/m2 Wind resistance: Grade 11(wind speed≤111.5km/h)Earthquake resistance: Grade 84. Loadability (Packing):  One 40’HQ container can load such prefab houses about 300~350 square meters.5. Features and Advantage: Tightly airproof, heat insulated and preservation, waterproof, resistant to fire and moisture proof; Easy assembly and disassembly, flexible layout, green and environmental friendly; Beautiful in design and structure; color-coated steel sheet used in and out of the house; good appearance and effectiveness; the trade-off between design and color. Over 20 year’s life span by normal use; space-saving for container shipping; repeatable and recycled; material and labor extremely cost-efficient.
