Review
Since the implementation of the reform and opening up policy, mainland cities and rural areas have gradually formed two incompatible economies to develop in different directions, in the city can often see perfect infrastructure construction, here are high-rise buildings, is for the struggle of workers shuttled through the traffic; and the countryside is a lonely and desolate, there are no high-rise buildings, only some low but practical bungalows.
However, a few years ago, the countryside began to be popular color steel tile houses, those years we can obviously see back to our hometown, some people's roofs are very beautiful, color steel tile houses are cost-effective, you can also avoid water, snow hidden dangers, it can be said that it is deeply loved by the people.
Even the temporary buildings in the city are built with this material, because the color steel tile house is very easy to build and the stability is better than other materials, which is its general popularity. Later, these colored steel tile houses suddenly disappeared, because the local governments had clearly ordered them to be demolished to avoid causing excessive public harm. This is strange, obviously it looks very cost-effective color steel tiles, in the end can bring us what kind of serious harm?
The color steel tile house is quite popular with the Chinese people
Color steel tiles, a building material, were not produced independently by the mainland at the earliest, but were imported from the United States around the 1960s and were generally welcomed by the domestic market. Compared with wood, red brick and other building materials, the advantages of color steel tiles are very obvious, its life expectancy is generally 8 to 20 years, if the maintenance is good, 30 years can also be barely maintained.
However, everyone initially used color steel tiles is not the advantage of its life, after all, there are countless materials that are stronger and more durable than color steel tiles, and what really impresses everyone is the price.
The construction cost of color steel tiles is extremely low, may be less than 30 yuan per square, and the price of some slightly lower quality color steel tiles can be reduced to at least 10 yuan per square, which is an advantage that other building materials cannot match.
Sometimes due to the compact construction period, many temporary housing in the city are used as the main building material, from its production to the application of the building at least one week, eliminating the complexity of transportation like other materials, can shorten the temporary construction period by more than 40%, saving a lot of labor and large raw material costs.
Not only that, the temporary housing built with color steel tiles is not worse than other expensive materials in terms of rain leakage and heat insulation, and the key is that its seismic effect can also withstand the test.
Remember that when the Sichuan earthquake did not know how many victims were homeless, the government built a color steel tile house when relocating them temporary residences, the construction period was urgent, and the efficiency of other building materials was really not as high as the color steel tile, since then the color steel tile is completely opened up to the mainland market, which is widely welcomed by everyone.
In the past few years, this kind of color steel tile house is popular in rural areas, and the unique advantages of color steel tile have greatly benefited farmers, whether it is used to build temporary residences or warehouses.
Color steel tile itself is very bright color, customers can choose different colors according to personal preferences; and because the domestic color steel tile guide uses cold bending processing technology to produce, which makes its hardness rise again by a grade, farmers prefer to use double-layer color steel tiles to build houses in order to improve the quality of the house.
There are huge hidden dangers in the use of color steel tile houses
However, if we are careful enough, we will find that there are fewer and fewer houses made of colored steel tiles in both urban and rural areas, and many houses that have just been built have been demolished.
The reason for this is that the government has issued an explicit policy, which clearly stipulates that the color steel tile house should be demolished, because its harm is suddenly revealed. So what are the hazards of color steel tile houses?
The first and most important thing is security. It is precisely because the construction process of the color steel tile house is simple, many people do not need to ask a professional installation team at all, and the roof of a family may be installed in one day, which can also save themselves a lot of money.
However, in fact, the people lack the understanding of color steel tiles, and their fixed points and bearing points are easily misplaced during installation, so that there are great hidden dangers in subsequent use. This kind of hidden danger may not burst out on normal days, but what if it is a typhoon or heavy rainfall? The consequences are unimaginable.
The second is the fire hazard. As mentioned above, most people like double-layer color steel tiles, which have a layer of foam sandwiched in the middle of this color steel tile, which plays a role in shock absorption, heat protection and heat preservation; some people like to brush some paint on color steel tiles to do waterproof and moisture-proof effects.
Once a fire occurs, because the color steel tiles are covered with iron sheets, the foam combustion of the sandwich layer will release a large amount of toxic gases, which is a huge harm to the human body.
Then there is the hidden danger of residence. Don't look at the color steel tile construction is very cheap, but really use it to build a house is not so comfortable to live, nothing else, whenever it rains color steel tile house roof is always crackling, rain in the middle of the night this sound can wake people up. Moreover, the color steel tiles that are generally used can maintain a maximum life of 10 years, and they must be replaced regularly when they expire, which is very troublesome.
Finally, there are illegal buildings. Because of the short construction period of color steel tiles, many bosses engaged in the construction industry like to use it to temporarily build houses or warehouses, which not only do not have any formalities, but also have poor housing safety, which is a typical illegal product.
If we live here and have an accident, the boss does not have to lose a penny, and in the end it is himself who suffers, which is doomed to be demolished.
epilogue
For now, most of the city's color steel tile houses have been banned according to law, and the remaining ones that meet the regulations must also be filed with the relevant departments to prevent major hidden dangers.
Although rural areas are also gradually canceling color steel tile houses, the process is much slower than in the city, because many people use color steel tiles to build houses to live, and they must be more careful in the stability and safety of houses, but in the face of safety hazards, color steel tile houses still have to be resolutely demolished.
