1.镀锌板的定义
镀锌钢板是为防止钢板表面遭受腐蚀，延长其使用寿命，在钢板表面涂以一层金属锌，这种涂锌的薄钢板称为镀锌板。
2.镀锌板的分类和用途
按生产及加工方法可分为以下几类：
①热浸镀锌板。将薄钢板浸入熔解的锌槽中，使其表面粘附一层锌的薄钢板。目前主要采用连续镀锌工艺生产，即把成卷的钢板连续浸在熔解有锌的镀槽中制成镀锌钢板；
②合金化镀锌钢板。这种钢板也是用热浸法制造，但在出槽后，立即把它加热到500℃左右，使其生成锌和铁的合金被膜。这种镀锌板具有良好的涂料的密着性和焊接性；
③电镀锌钢板。用电镀法制造这种镀锌钢板具有良好的加工性。但镀层较薄，耐腐蚀性不如热浸法镀锌板；
④单面镀和双面差镀锌钢板。单面镀锌钢板，即只在一面镀锌的产品。在焊接、涂装、防锈处理、加工等方面，具有比双面镀锌板更好的适应性。为克服单面未涂锌的缺点，又有一种在另面涂以薄层锌的镀锌板，即双面差镀锌板；
⑤合金、复合镀锌钢板。它是用锌和其他金属如铅、锌制成合金乃至复合镀成的钢板。这种钢板既具有卓越的防锈性能，又有良好的涂装性能。
