沈阳方管市场暂稳观望。今日鞍钢国贸4010元盘价维稳，本地方管厂家也维稳观望以待后市。昨日晚间美联储宣布降息，但今日对期货市场并未激起多大水花，早盘开市，期货价 格仍以回落开局，下午盘加速回落。本地方管厂家出货不佳。据悉，连日来，由于处于淡季，方管出货一直欠佳，市场大户出货在300-400吨，有时不到 200吨。多数方管厂家表示，地处淡季，下游拿货积极性偏差，鞍钢和营口资源均到货正常，尽管唐山在出台环保政策，但是对沈阳当地环保政策却迟迟不动，方管厂家库存不敢累积太多，钢厂盘价也基本在4000左右波动，最低价格是3980元，在成本的支撑下，方管厂家操作上也偏于挺价，致使本地方管价格近一周一直变化不大。当前沈阳方管格局供需基本处于平衡状态，在此情况下，预计明日沈阳方管价格亦呈现盘中盘整格局。

Shenyang Fangguan Market is on the sidelines for a while. Today's Angang International Trade 4010 yuan price is stable, local management manufacturers are also stable to wait for the future market. Yesterday evening, the Federal Reserve announced interest rate cuts, but today's futures market did not stir much water. The market opened early, futures prices still started to fall, and the afternoon market accelerated to fall. Local managers have poor delivery. It is reported that in recent days, due to the off-season, square tube shipment has been poor, large market households shipped 300-400 tons, sometimes less than 200 tons. Most square managers said that in the off-season, the enthusiasm of downstream picking up goods was biased, and the resources of Angang and Yingkou arrived normally. Despite Tangshan's environmental protection policy, the local environmental protection policy of Shenyang was slow to move. Businessmen dared not accumulate too much stock. The price of steel mills fluctuated around 4000, with a minimum price of 3980 yuan. Supported by cost, square tube manufacturers are also biased in their operation, resulting in little change in local local tube prices in the past week. At present, the supply and demand of Shenyang Square Pipe pattern are basically in balance. In this case, it is expected that Shenyang Square Pipe Price will also present a consolidation pattern in the market tomorrow. 方管价格方面：1日沈阳:普8mm方管鞍钢4110元(吨价，下同)，普10mm鞍钢3980元，普20mm鞍钢、营口3890元，锰板加150元。
