镀锌板的表面色泽。对于小锌花、无锌花产品，通过光整可以使镀锌板获得一个光泽度更加均匀一致的表面。对于某些民营企业采用大锌花产品作为彩涂基板来说，能使大锌花因结晶形成的锌花凸点和不同的光泽度平整统一，使锌花变得模糊不清，有利于在涂装时遮盖掉锌花。

Surface color of the galvanized plate.For small zinc flower, zinc-free flower products, through the galvanized plate can obtain a more uniform gloss surface.For some private enterprises to use the large zinc flower products as the color coating substrate, can make the large zinc flower crystallization formed by the zinc flower convex points and different gloss smooth and unified, so that the zinc flowers become blurred, is conducive to cover the zinc flowers when painting.

也正是因为镀锌板的用途有这么多的分类，所以镀锌板价格在某些方面也有些差异。主要用于镀锌板等金属制品组件及材料的封存防锈。适用范围：适用于镀锌板、金属制品组件及材料的封存防锈处理，上助镀剂将钢构件浸于氯化锌与氯化铵的混合液中，使构件表面与空气相隔，防止氧化生锈，并使表面铁分子活化，使构件在热锌溶液中更易达成铁锌化合的反应;MIG电弧钎焊可用来焊接低合金钢、非合金钢以及不锈钢，主要用途还是焊接表面有镀层的钢板。熔滴过渡带来的热量就使镀锌层挥发，进入熔池的锌蒸汽很少，在凝固过程中又继续排出，因此焊缝中残留气孔极少。主要用途：建筑工程、机械制造、容器制造、造船、桥梁等。虽然镀锌板的使用范围很广泛，但是镀锌板厂家们也不能盲目的生产，一定要根据需求的情况而定。

It is precisely because there are so many classifications of galvanized plates that the price of galvanized plates varies in some ways.It is mainly used for galvanized plate and other metal product components and rust prevention materials.Scope of application: suitable for sealing and rust treatment of galvanized plates, metal product components and materials, immerse steel member in the mixture of zinc chloride and ammonium chloride to separate the member surface from air, prevent oxidation and rust, and activate surface iron molecules to achieve iron and zinc compound in hot zinc solution; MIG arc brazing can be used for welding low alloy steel, nonalloy steel and stainless steel for the main purpose.The heat brought by the melting drop transition will volatilize the galvanized layer, with very little zinc vapor entering the melting tank and continuing to discharge during solidification, so there are very few residual stomata in the weld.Main uses: construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge, etc.Although the use range of galvanized plate is very wide, but the galvanized plate manufacturers can not blindly produce, must be determined according to the situation of the demand.

近几年，我国镀锌板的生产量逐年增加，而进口量也在逐年增长，增长幅度甚至高于生产量的增幅；相信随着镀锌板的不断改进与发展，在乐从钢材批发市场中将会原来越多的见到它的身影！

In recent years, the production of galvanized plate has increased year by year, and the import volume is increasing year by year, even higher than the production rate; I believe that with the continuous improvement and development of galvanized plate in the Lecong steel wholesale market!
