<p><p>据新市场报告，近一周，国内现货镀锌方管价格综合指数报收于135.98点，一周下跌2.58%。目前，现货镀锌方管价格继续整体回落，市场“追高不追跌”，下游采购谨慎，而钢贸商却急于出货，价格不断松动，但总体成交平淡。虽说目前尚处于传统的消费旺季，但市场的看涨信心与接货意愿相对不足。<br /> 据分析，在建筑钢市场上，价格出现不同程度的下跌。等地一周吨价跌幅均超100元。在等地的市场可以看到，镀锌方管期货价格在走低，现货镀锌方管价格也在回落，市场“看空”氛围再度加强。主导镀锌方管厂的新出厂定价虽然还在表现强势，但相对较弱的需求是抑制价格实际走势的重要因素。<br /> 在板材市场上，价格总体下跌。热轧板卷价格出现不同程度的下跌，其中场价格的周跌幅为240元，居于。在一些地区，市场心态偏弱，部分商家有“抛货”的现象。一些成交尚可，但总体接货不畅，下游多按需采购。中厚板价格止涨返跌，等地吨价一周下跌超过100元。市场的观望情绪浓厚，需求持续减弱。<br/><img

/><br/>镀锌带方管一般分冷镀锌和热镀锌，冷镀锌也可称为电镀锌，冷镀锌工艺用于保护金属防止腐蚀，为此利用了锌填料的涂料，在利用任何一种涂敷的方法将其涂在被保护表面，干燥之后形成锌填料涂层，在干燥涂层中具有含量的锌（达到95%）。适合于修理工作（即在修理工作过程中，仅在被保护的钢表面损伤的地方，只要修理好表面就可以重新涂敷）。冷镀锌工艺用于各种钢制品和构筑物的防腐。(冷镀锌就是电镀锌，镀锌量达到95%，其本身的耐腐蚀性比较好。采用电镀锌的价格相对便宜一些。实际上,冷镀锌的效果,适合应用于修补，防腐蚀,具有的防锈功能；防锈性能超过电镀或热镀锌层；擦破漆膜后，对底层金属仍有保护作用。钢铁在冷却的条件下在表面镀锌，而热镀锌是钢管在热浸的条件下对表面镀锌，它的附着力很强，不容易脱落，热镀锌管虽然也出现锈蚀的现象，但在很长的周期可以满足技术、卫生要求。电镀层均匀，厚度很薄；热镀层较厚，厚度不均匀。电镀外观光亮，热镀颜色较暗。<br/><img
