日本日新钢铁公司继锌系、铝系、锌铝系热镀层钢板之后，最近又开发出锌铝锰热镀层钢板。可用作预制结构住宅材料、卷帘式铁门、土木加工产品等要求耐蚀性高的建筑材料，现已开始正式生产。在镀锌层中添加锰，可提高耐蚀性，但添加易氧化的锰构成镀层，技术难度很大，因此在世?
Japan’s Nisshin Steel Corp. has recently developed zinc-aluminum-manganese-hot-dipped steel sheets following zinc-, aluminum-, and zinc-aluminum-based hot-dipped steel sheets. It can be used as prefabricated residential materials, rolling shutters, civil engineering products and other building materials that require high corrosion resistance, and has now begun production. The addition of manganese to the galvanized layer can improve the corrosion resistance, but the addition of easily oxidizable manganese constitutes a plating layer, and the technology is very difficult, so it is in the world?
