Shanghai copper up

The most-traded copper contract on the Shanghai Futures Exchange finished up 2.8 percent to 51,840 yuan a tonne on Friday buoyed by expectations of strong demand in top industrial metals consumer China. Early readings on Chinese manufacturing are due on Saturday ahead of a week-long holiday. China's factories likely cranked up activity for the 14th straight month in September as the country's year-long building boom and higher prices generate hearty profits, though the pace of growth may have eased slightly from August.
