本周杭州方管市場價格大幅下跌，截至8月30日，杭州方管批量成交指導價格：沙鋼 Φ8-10mm高線為3990元,比上周同期降120元，中天Φ12mm三級螺紋鋼為3790元，比上周同期降80元；中天Φ25mm三級螺鋼為3630 元，比上漲同期降80元。永鋼Φ8-10mm三級盤螺為3990元，比上漲同期降100元。周初兩日，杭州方管廠家多次下調報 價，兩日降幅在120-130，隨后幾日，期螺超跌反彈，吸引了一部分抄底需求，另有一些終端企業開始出現明顯的低價補貨和收貨，市場低價成交量有所增 加，但高價成交仍然吃力，現貨價格基本穩定，周五，受29日晚中美磋商消息影響，期貨有一定拉漲，現貨也隨之上漲40，成交尚可。

This week, the market price of Hangzhou square pipe dropped sharply. As of August 30, the guiding price of Hangzhou square pipe volume transaction: Shagang 8-10mm high line was 3990 yuan, 120 yuan lower than the same period last week, Zhongtian_12mm third-class thread steel was 3790 yuan lower than the same period last week, 80 yuan lower than the same period last week; Zhongtian_25mm third-class thread steel was 3630 yuan, 80 yuan lower than the same period of increase. Yonggang 8-10mm three-stage snail is 3990 yuan, 100 yuan lower than the same period of increase. 

On the first two days of the week, Hangzhou Fangguan manufacturer lowered its quotation many times, with a decline of 120-130 in two days. Then, the snail overfall rebounded in a few days, which attracted a part of the demand for bottom-copying. Other terminal enterprises began to appear obvious low-price replenishment and receipt. The market volume of low-price transactions increased, but high-price transactions were still laborious and spot prices were still difficult. Basically stable, on Friday, affected by the news of the Sino-US consultation on the evening of the 29th, futures rose to a certain extent, spot also rose by 40, and trading was still acceptable.

供需矛盾仍然尖銳。唐山市發布《全市大氣污染防治強化管控方案》初稿，較《意見稿》相比，第二階段部分方管廠家限產比例上調，但整體限產力度依然較為寬松。不過在唐山環保限產等因素的影響下唐山地區的方管廠家的產量確實是有明顯的減少，但宣鋼、承鋼等不受唐山限產管控的方管廠家仍然保持正常生產，8月29日，商務部召開 新聞發布會，宣布中美雙方經貿團隊一直保持有效溝通，關于9月份赴美磋商，雙方正在討論中，當前最重要的是為雙方繼續磋商創造必要的條件。

The contradiction between supply and demand is still acute. Tangshan City issued the preliminary draft of "Intensified Control Plan for the Prevention and Control of Air Pollution in the City". Compared with the "Opinion Draft", the proportion of production limitation increased in the second stage, but the overall capacity limitation is still relatively loose. However, under the influence of Tangshan's environmental protection and production restriction factors, the output of local managerial factories in Tangshan area has obviously decreased, but Xuan Gang, Chenggang and other local managerial factories which are not controlled by Tangshan's production restriction still maintain normal production. On August 29, the Ministry of Commerce held a press conference to announce that the economic and trade teams of China and the United States have maintained an effective ditch. Tong. As for the September consultation with the United States, the two sides are discussing. At present, the most important thing is to create the necessary conditions for the two sides to continue the consultation.

庫存方面：本周杭州方管庫存79.75萬噸：較前期整體庫存降3.87萬噸：線材3.75萬噸，螺紋鋼76萬噸

Inventory: Hangzhou square pipe inventory 797.5 million tons this week: 38.7 million tons lower than the previous overall inventory: 37.5 million tons of wire rod, 760,000 tons of threaded steel

據統計30日唐山主要倉庫鋼坯庫存約42.2萬噸，較上周(23日)增8.5萬噸，主導大庫庫存增加明顯

According to statistics, the stock of billets in the main warehouse of Tangshan on the 30th day was 422,000 tons, an increase of 85,000 tons compared with last week (23 days). The stock in the main warehouse increased significantly.

原材料方面：30日16:30昌黎部分鋼坯資源降40，現普碳方坯含稅出廠3300元。

Raw materials: 30:30 Changli part of the billet resources decreased by 40, now ordinary carbon billet with tax factory 3300 yuan.

近期來看，從基本面來看，本周庫存處于下降通道，這也說明了本周利好消息所刺激出來的抄底需求對庫存消化起到了不小的作用。不過方管廠家方面，后期限產力度如何 還需觀望，產量方面是利好還是利空先畫個問號，但中美關系有望緩和卻是眼下的明顯利好，或對下周行情有所支撐。故預計下周行情或窄幅調整。預計下周杭州方管市場價格或窄幅調整。

In the near future, from the basic point of view, this week's inventory is in the decline channel, which also shows that the good news this week stimulated the demand for bottom-reading has played a very small role in inventory digestion. However, in the case of manufacturers, it is still necessary to wait and see how the late production limit is going to work. Whether the output is good or bad is the first question mark. However, the expected easing of Sino-US relations is an obvious advantage at the moment, or a support for the market next week. Therefore, the market is expected to adjust in a narrow range next week. It is expected that the market price of building materials in Hangzhou will be adjusted in a narrow range next week.
