镀铝锌光板是冷轧钢带为基板，经过连续热浸镀铝锌工艺而生产出来的镀铝锌板产品。        镀铝锌板具有耐腐蚀强、表面质量好、得利于深加工、经济实用等特点。表面呈特有的光滑、平坦和华丽的星花，基色为银白色。铝锌钢板的镀层成份按重量比率分别由55%的铝和43.4%的锌，1.6%的硅组成。镀铝锌钢主要用于建筑、家电、汽车、容器、交通及家业等领域。特别是钢结构建筑、汽车制造、钢板仓制造等行业。    镀铝锌板的生产工艺是连续熔融镀层工艺。金属镀层产品的长期耐腐蚀性能主要取决于镀层物的融解率和镀层的厚度，镀锌钢板的镀锌层融解率比55%铝锌合金镀层的镀铝锌钢板的融解率高。因此55%铝锌合金镀层的镀铝锌钢板的使用寿命比镀锌钢板要长，经过20年后约无锈蚀迹，基板采用55%铝的铝锌合金镀层，其防锈蚀可达50年以上。
