电镀锌钢板是指采用电镀锌工艺镀锌的钢板。与热镀锌钢板相比,镀锌层厚度薄,但成本低。
镀锌又称冷镀锌, 彩钢板价格表是利用电解原理在工件表面形成均匀、致密、结合良好的锌层的过程。与其他金属相比,锌相对便宜,容易镀。它是一种低值耐腐蚀的电镀层,广泛应用于保护钢制件,特别是防止空气氧化腐蚀和装饰。
镀锌板是指表面有一层锌的钢板。镀锌是一种经济有效的防腐方法。全世界约一半的锌生产用于这一过程。镀锌是为了防止钢板表面的腐蚀,延长钢板的使用寿命。

彩钢板价格表 镀锌板市场及生产消费概况
近年来,我国镀锌板产量逐年增加,进出口量也逐年增加,增速高于产量增幅;扣除生产重复统计,镀锌板消费量约527万吨。自1999年以来,进口量超过生产量,国内产品自给率不足50%,并有逐年下降的趋势。
彩钢板价格表 镀锌钢消费量的增长主要依靠进口。近年来,镀锌钢进口逐年增加,进口产品主要品种为镀锌钢,但进口镀锌钢所占比重逐年下降。相应地,进口镀锌钢的比重也在逐年提高。2003年,我国镀锌钢进口量首次超过镀锌钢进口量。
镀锌钢板的特点:电镀生产的镀锌钢板具有良好的加工性能,但镀层较薄,耐蚀性不如热镀锌钢板。

Electro galvanized steel sheet refers to the steel sheet galvanized by electro galvanizing process. Compared with hot-dip galvanized steel

sheet, the thickness of galvanized layer is thin, but the cost is low. Galvanizing, also known as cold galvanizing, is the process of forming uniform, dense and well combined zinc coating on the surface of the workpiece by using the principle of electrolysis. Compared with other metals, zinc is relatively cheap and easy to be plated. It is a low value corrosion-resistant electroplated layer, which is widely used to protect steel parts, especially to prevent air oxidation corrosion, and for decoration. Galvanized sheet refers to the steel plate with a layer of zinc on its surface. Galvanizing is an economic and effective anticorrosion method. About half of the world's zinc production is used in this process. Galvanizing is to prevent the surface of steel plate from corrosion and prolong its service life. General situation of galvanized sheet market and production and consumption In recent years, the production of galvanized sheet in China is increasing year by year, the import and export volume is also increasing year by year, the growth rate is higher than the increase of production volume; after deducting the repeated statistics of production, the consumption of galvanized sheet is about 5.27 million tons. Since 1999, the import volume has exceeded the production volume, and the self-sufficiency rate of domestic products is less than 50%, and there is a trend of decreasing year by year. The increase of galvanized steel consumption mainly depends on imports. In recent years, the import of galvanized steel has been increasing year by year, and the main varieties of imported products are galvanized steel, but the proportion of imported galvanized steel has been decreasing year by year. Accordingly, the proportion of imported galvanized steel has been increasing year by year. In 2003, for the first time, the import of galvanized steel in China exceeded the import of galvanized steel. Characteristics of galvanized steel sheet: the galvanized steel sheet produced by electroplating has good processability, but the coating is thinner and the corrosion resistance is not as good as that of hot dip galvanized steel sheet.
