Here's an interesting article comparing Chinese steel and American steel: https://gensteel.com/building-faqs/b...steel-quality/

"There have been a large number of reports of Chinese steel quality issues. Between 2011 and 2012 eight bridges in China, using Chinese steel, collapsed. In 2008 an earthquake struck the Sichuan province, and in one steel school that was poorly built, 700 children were crushed to death."

While it may not "make sense" to our minds for them to use low quality steel in vital infrastructure, they still do it a whole lot more than we do in the U.S.
