镀锌板是指表面镀有一层锌的钢板，这种涂锌的钢板是为了防止钢板表面遭受腐蚀、延长其使用寿命。镀锌板由于涂镀工艺中处理方式不同，表面状态也不同，如普通锌花、细锌花、平整锌花、无锌花以及磷化处理的表面等。德国标准还规定有表面级别。镀锌板应具有良好的外观，不得有对产品使用有害的缺陷，如无镀、孔洞、破裂以及浮渣、超过镀厚、擦伤、铬酸污垢、白锈等。
Galvanized steel plate refers to a steel plate coated with alayer of zinc on its surface. This type of galvanized steel plateis designed to prevent surface corrosion and extend its servicelife. Galvanized sheet has different surface states due todifferent treatment methods in the coating process, such asordinary zinc flower, fine zinc flower, flat zinc flower, no zincflower, and phosphated surface. German standards also specifysurface grades. Galvanized sheet should have a good appearance andshould not have defects that are harmful to product use, such as noplating, holes, cracks, floating slag, exceeding plating thickness,scratches, chromic acid dirt, white rust, etc.
