Chinese steel futures fell for a third day on Friday, with demand in the world's top consumer of the metal expected to slow over winter and as the economy cools.
China's industrial output, fixed asset investment and retail sales missed expectations for last month, raising concerns that falling property investment growth would hit steel demand.
Steel appetite is also set to falter as cold temperatures in northern regions crimp construction activity and as the government orders curbs to industrial production as part of its campaign against pollution.
“Investors are increasing bearish on steel demand as the economy and property investment growth is slowing,” said a researcher with an investment firm in Shanghai.
“Meanwhile, steel demand is weakening as construction activity is hit by the cold weather and the government's crackdown on environmental pollution.”
