* Shanghai rebar futures extend gains
* Dalian iron ore down nearly 1% (Recasts; updates with closing prices)
BEIJING, Dec 20 (Reuters) - Benchmark steel rebar futures in China edged up on Friday, but posted a weekly fall, as market retraced after a robust gain last week amid demand uncertainties.
The most-actively traded construction steel rebar on the Shanghai Futures Exchange, for May 2020 delivery, closed up 0.3% at 3,507 yuan per tonne. It fell 0.5% for this week, retreating from a 2.5% gain the week earlier.
Hot-rolled coil, used in cars and home appliances, fell 0.7% to 3,526 yuan per tonne.
“(The decline) is price adjustment by market,” said Liu Xinwei, iron and steel researcher at Sublime China Information. “It rose too much before without sufficient reasons.”
Liu said prices are expected to further revise before economic stimulus pledged by government finally landed.
