The four series prefabricated houses are: 1. JH Prefabricated House Series 1-------K Modular Prefabricated House with double pitched slope(one storey, two storey, three storey); This series of prefabricated houses are all made of standardized components, take K as modulus(1K=1820mm) for .the length and width of our prefab house The horizontal size of the house is nK+160 and the vertical size is nK+160. Number of floors is denoted by the P modulus (1P=0.95m), 3P being one storey , 6P two storey, 9P three storey. Important Notice: the size of every single piece of sandwich panel forming the wall of JH Prefabricated House Series 1,2,3 is standard as 1820mm(L)*950mm(W) and particularly designed to connect each other by insertion without using any connecting accessories.
