镀锌脚手架价格继续追涨。周末唐山突发的限产通知又让钢市炸开了锅，与以往不同的是此次限产力度较大且要求24日环保组进驻钢铁企业督促企业6月27日之前停限产到位，目前脚手架厂家基本接到相关通知。受其消息带动加之地方债发行创年内新高的消息，钢坯从周末截至24日连续上涨达百元，河北地区镀锌脚手架出厂报价上调60-100元不 等，且成交有明显好转，各管厂均反应有缺货和抢货的现象。现河北主流管厂镀锌脚手架4寸(3.75mm)出厂报价在4050-4380元，镀锌管4寸 (3.75mm)出厂报价5070-5270元，今日普遍上调幅度在50元左右。但与之相对应的下游市场却并没有这么乐观，从笔者了解到的情况来看，由于 终端需求不景气，脚手架厂家出货依然较弱，商家少量补货，操作普遍以出货为主，市场心态仍偏消极。短期来看，受原料端有力支撑，镀锌脚手架价格将继续坚挺，但需谨 慎利好被市场消化以后市场回归供需基本面所带来的价格回落。

Galvanized square tube prices continue to catch up. At the weekend, Tangshan's unexpected notice of production restriction made the steel market explode again. Unlike the previous one, this time, the intensity of production restriction was greater and the environmental protection group was required to enter the steel enterprise on June 24 to urge the enterprise to stop production restriction in place before June 27. At present, the square management manufacturer has basically received the relevant notice. Driven by the news and the local bond issuance hit a new high in the year, billets rose by 100 yuan from weekend to 24, and the quotation of galvanized square tubes in Hebei increased by 60-100 yuan, and the turnover improved markedly. All the pipe plants reacted to the phenomenon of shortage and rush of goods. Now Hebei mainstream pipe factory galvanized square pipe 4 inch (3.75mm) ex-factory quotation is 4050-4380 yuan, galvanized pipe 4 inch (3.75mm) ex-factory quotation is 5070-5270 yuan, today the general increase is around 50 yuan. However, the corresponding downstream market is not so optimistic. From what I know, due to the recession of terminal demand, TRADERS'shipment is still weak, merchants make up a small amount of goods, and the operation is generally dominated by shipment. The market mentality is still negative. In the short term, galvanized square pipe prices will continue to be strong supported by the raw material end, but we need to be careful to take advantage of the price drop brought by the market's return to supply and demand fundamentals after being digested by the market. 价格方面：国内重点城市4寸(3.75mm)镀锌脚手架的平均价格为4245元，比上周五价格上 涨29元，中心城市报价其中唐山上调90元、天津上调30元、北京上调20元、西安涨50元、济南涨20元、广州涨60元、成都涨20元，个别地区暂未跟涨。
