短期镀锌方管价格将继续盘整为主厂家多挺价…方管镀锌方管价格暂稳运行。今日期盘宽幅震荡，早盘翻红提振市场信心，镀锌方管厂多挺价观望，但随着午后跳水现货后劲不足，镀锌方管厂成交不畅，现河北主流方管厂镀锌方管 4寸(3.75mm)出厂报价在4000-4400元，镀锌方管4寸(3.75mm)出厂报价5140-5200元。总的来看，端午节即将来临，下游节前采 购意愿较差，迟疑观…

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，并在这种方管的根底大将方管置于热镀锌池中经过一系列化学反应后又形成的一种方管。热镀锌方管的出产工艺较为简略，且出产功率是很高的，种类标准也多，这种方管所需求的设备和资金很少，适合小型镀锌方管厂家的出产。可是从强度上来说这种钢管的强度是远远低于无缝方管的。
In brief, the centralized classification of galvanized square tubes can be divided into hot galvanized square tubes and cold galvanized square tubes. It is precisely because of the different addition of these two galvanized square tubes that many different physical and chemical properties of them are created. Generally speaking, they differ in strength, endurance and mechanical function. Hot-dip galvanized square pipe: a square pipe which is welded by bending of steel plate or strip and placed in a hot-dip galvanizing bath at the root of the square pipe after a series of chemical reactions. The production process of hot-dip galvanized square tubes is relatively simple, and the output power is very high, and there are many kinds of standards. The square tubes require little equipment and capital, which is suitable for the production of small-scale galvanized square tubes manufacturers. But in terms of strength, the strength of this kind of steel pipe is far lower than that of seamless square pipe. ??而冷镀锌方管是在所用的方管上使用冷镀锌的原理来使方管具有防腐蚀的功能。与热镀锌不同冷镀锌涂料首要经过电化学原理来进行防腐，因而必须保证锌粉与钢材的充分触摸，发生电极电位差，所以钢材外表处理很重要。
And the cold galvanized square pipe is to use the principle of cold galvanizing on the square pipe used to make the square pipe have the function of anti-corrosion. Different from hot-dip galvanizing, cold-dip galvanizing coatings are mainly anticorrosive by electrochemical principle. Therefore, it is necessary to ensure the full touch between zinc powder and steel, and the potential difference between electrodes occurs. Therefore, the surface treatment of steel is very important.

镀锌方管有热镀锌方管和电镀锌方管两大类。热镀锌方管有湿法、干法、铅锌法、氧化还原法等。不同热镀锌办法的首要差异在钢管酸浸清洗后，用什么办法活化管体外表进步镀锌质量。现出产中首要选用干法和氧化还原法，其特点见表。电镀锌的锌层外表非常光滑细密、组织均匀;具有杰出的力学功能和抗腐蚀能力;锌耗比热镀锌低60%～75%。电镀锌在技术上有一定的复杂性，但对单面镀层，内外外表镀层厚度不同的双面镀层，以及薄壁管镀锌等皆须选用此法。
_galvanized square tubes can be divided into hot galvanized square tubes and galvanized square tubes. Hot-dip galvanized square pipe has wet method, dry method, lead-zinc method, oxidation-reduction method and so on. The primary difference between different hot-dip galvanizing methods is how to activate the outside surface of the pipe to improve galvanizing quality after acid leaching cleaning. Dry method and redox method are the most important methods in production. Their characteristics are shown in the table. The zinc coating of galvanizing is very smooth, compact and uniform in structure. It has excellent mechanical function and corrosion resistance. The consumption of zinc is 60%-75% lower than that of hot galvanizing. Electroplating zinc is technically complicated, but it is necessary to select this method for single-side coating, double-sided coating with different thickness of inner and outer coating, and thin-walled tube galvanizing.

国内方管价格亦或有趋弱可能厂家心态较为积…方管方管市场价格基本维稳。价格方面：由于期货震荡影响，方管市场价格略受波动，不过好在有利好支撑，各区域价格基本保持坚挺态势。华北区域：在环保迫切趋严情况下，相对于市场仍有一 定的刺激作用，因此方管厂家心态较为积极。不过，北方市场需求不及南方，因此价格上涨空间受限。华东区域：其环保相比北方没有那么严峻，因此… 银川方管价格多是继续以稳为主市场需求一般…方管银川市场方管价格基本稳定，市场成交一般。从市场上了解到，近期酒钢、八钢资源到货不多，市场库存小幅下降。据不完全统计，现在银川市场方管库存 量在0.4万吨，比上周减少0.05万吨。由于方管厂家目前库存多是前期高价成本，即使目前市场需求一般，也无降价意愿，多是继续持稳销售。需求方面，虽然宁 夏地区今年以来有较多风…
