According to the results obtained from iron smelting research, the extent of destruction caused by earthquakes is very high, even among newly built buildings with apparently strong frames, and one of the reasons for this is the use of non-standard materials. The countries on the southern edge of the Persian Gulf apply very strict regulations to construction steel.
Also, in the oil industry, from the beginning of the 1980s, petrochemicals and refineries were first removed from the National Persian Oil Company, then they were not integrated and were handed over separately.
