生产工艺上浅谈镀锌方管的区别方管简单聊聊镀锌方管的集中分类，我们先从其出产工艺上来看，这样是可以分为热镀锌方管和冷镀锌方管的。正是由于这两种镀锌方管的加不相同也就造就了它们许多不同的物理和化学性质。总的来说它们在强度、耐性和机械功能方面都有许多的差异。热镀锌方管：是在运用钢板或者是钢带弯曲成型后焊接制成的方管，并在这…

方管市场主跌个稳。周一开盘，期货市场疲弱下行，国内方管市场报价主跌个稳。目前国内主导城市：邯郸武安、天津、江阴、上海、乐从等区域价格分别运行在3870、 3850、3810、3920、4050元左右。较月初相比，华北市场邯郸持稳；天津跌30元；华东、华南市场江阴跌110元；上海跌90元；乐从跌20 元。在环保限产的影响下，北方价格较为强势，南方则由于限产不迫切，敏感度较低，价格支撑力度不足，下跌幅度相比于华北较大，不过，整体来看，7月市场来 回拉锯震荡，因此方管价格变化相对不大。区域价差则因南北钢价下跌幅度不同，略有扩大，但影响不大。目前截至收盘，期螺收于3877元，跌63元。另据市 场了解，午后随着期盘继续下行，邯郸、江阴等地二次下调10-30元，可见，市场交投氛围较差，成交受阻。因此明日来看，在月末阶段下，国内方管或继续稳中趋弱格局。

The market has fallen steadily. At the opening of Monday, the futures market was weakening, and the domestic market prices fell steadily. At present, the regional prices of Handan, Wuan, Tianjin, Jiangyin, Shanghai and Lecong are running around 3870, 3850, 3810, 3920 and 4050 yuan respectively. Compared with the beginning of the month, Handan held steady in North China; Tianjin dropped 30 yuan; Jiangyin in East and South China dropped 110 yuan; Shanghai dropped 90 yuan; Lecong dropped 20 yuan. Under the influence of environmental production restriction, prices in the north are relatively strong, while in the south, due to the lack of urgency, sensitivity and price support, the decline is larger than that in North China. However, overall, the market oscillates back and forth in July, so the change of square tube prices is relatively small. The regional price gap is slightly widened due to the different declining ranges of steel prices between the north and the south, but the impact is not significant. At present, as of the close of the market, futures snails closed at 3877 yuan, down 63 yuan. According to market understanding, in the afternoon, with the futures market continued to decline, Handan, Jiangyin and other places cut 10-30 yuan twice. It can be seen that the market trading atmosphere is poor and trading is blocked. So tomorrow, at the end of the month, domestic management will continue to stabilize and weaken. 方管价格方面，截至7月29日，国内重点城市16-25mm普板主流价格保持在3952元(吨价，下同)，均价较上个交易日跌8元，较上周同期跌12元，较上月同期涨18元。

As for square price, as of July 29, the mainstream price of 16-25mm board in key cities in China remained at 3952 yuan (ton price, the same below). The average price was 8 yuan lower than the previous trading day, 12 yuan lower than the same period last week and 18 yuan higher than the same period last month.
