Why did Guangshan County tear down the steel tile house?

There are great security risks in such a house. At present, the thickness of single-layer steel tiles sold in the market is often less than 1cm, which leads to houses built with steel tiles that are neither thermal insulation nor sound insulation. In summer, the steel tile house is extremely hot. If it rains heavily again, there will be a loud noise in the room, just like in a drum, which is unbearable. Materials are often flammable, but once a fire happens, it is inside the steel tile, which can't be put out by traditional fire extinguishers, and polystyrene will produce deadly gas after burning. The superposition of these factors makes the color steel tile house a dangerous existence.
