BEIJING: Chinese steel futures advanced on Monday, with rebar and hot-rolled coil gaining more than 3%, lifted by attractive industrial profit margins and rising demand amid strong construction and manufacturing activity.

China's industrial profit surged 179% in the first two months from the year-ago period, data from the National Bureau of Statistics showed on Saturday.

Apparent demand for five main steel products, including steel rebar and hot-rolled coil, rose 5.6% week-on-week, data from Mysteel consultancy showed.

"According to the usual practice, if daily turnover for construction materials stays above 200,000 tonnes for a week, it can be proved that peak demand season has come," Tang Chuanlin, analyst with CITIC Securities said in a note.
