* Chinese steel-related futures trade flat from previous session
* Analysts warn record high steel output to weigh on prices
* However, more economic stimulus may underpin demand
SHANGHAI, July 15 (Reuters) - Chinese steel futures steadied on Friday, heading for its fourth weekly gain, as better-than-expected macro-economic data spurred hopes that easing monetary policy would underpin steel demand in the world's top producer.
China's economy grew 6.7 percent in the second quarter from a year ago, slightly better than expected, and Chinese banks extended 1.38 trillion yuan in net new yuan loans in June as Beijing stepped up efforts to stabilise growth in the world's second-largest economy. have climbed this week following the announcement of a mandated steel output cut in the key producing region of Tangshan city in China between July 12-31. However, one analyst cautioned that the measures were not being enforced as strictly as expected, cooling the market. analysts expected more potential stimulus from China will underpin steel demand and the country's campaign to tackle a supply glut will cap growth in steel production, while some warned that the rally was too quick and outpaced the spot market.
"The new yuan loans is higher than expected and this will support steel demand and we haven't seen any big correction on steel futures after the rally, suggesting the outlook remains positive," said Yu Yang, an analyst with Shenyin & Wanguo Futures in Shanghai.
But Xia Jun, an analyst with GF Futures in Foshan, warned that there has been no big improvement in fundamentals and futures surged too quickly driven by expectation of supply interruptions in Tangshan and on fund buying.
