Prefabricated houses have a long service life and are cheap. The material of the prefab house is made of light steel as the skeleton, so its service life is about 20 years. If you pay attention to the maintenance and upkeep of the prefab house during use, its service life will be relatively extended. . In the past few years, the price per square meter of prefabricated houses has dropped from 250 yuan per square meter, and it still includes installation and transportation costs.

The price of brand new prefabricated houses in 2021 is about 170 yuan to 190 yuan. For some better quality prefab houses, the price can still reach about 230 yuan. The reason why cheaper prefabricated houses are cheap is because the materials used have been It is not as good as before. The columns of prefabricated houses are now only 1.5 mm. The thickness of the original columns was about 1.8 mm. The cost of the entire frame has been reduced, and the wall panels of prefab houses are not as thick as before. Some prefab houses are now priced at a very low price. The wholesale price is only about 120 yuan per square meter. It is okay to build a one-story house like this, but it is a bit dangerous to build a two-story house because the materials used are relatively thin and the thickness of the columns is only 1.2 mm or 1.4 mm. And although the thickness of the board is said to be 5 centimeters of fireproof rock wool sandwiched in the middle, its density is not enough, and it only weighs 20 to 30 kilograms per cubic meter.
The price is very low, so remember, only one layer is enough, otherwise, the quality of the second layer will be worrying.
Prefab house pricing principles and area calculation methods
Single layer area = (Number of K in length direction X1.82+0.16) X (Number of K in width direction X1.82+0.16)
Double layer area = single layer area X2
The area of the stairs is calculated based on the horizontal projected area.
The platform area is calculated as half of the actual area.
Calculate the price based on square meters: square number * unit price + freight = final price
