Aluminum-coated zinc is mainly used to protect iron-based alloys that are prone to rust. Compared to pure galvanized steel, aluminum-coated zinc steel has stronger corrosion resistance because the zinc-aluminum alloy can protect the underlying steel from environmental erosion, while the zinc can also react with the adjacent steel to achieve self-repair. This is similar to galvanized steel.

Aluminum-coated zinc is a material applied to metals through the hot-dip process. Therefore, the thickness of aluminum-coated zinc steel coils is similar to that of hot-dip galvanized steel coils. The coating thickness varies depending on the substrate, and the hot-dip coating thickness is approximately 1 mil. Under the same coating thickness, the lifespan of aluminum-coated zinc steel is usually longer than that of galvanized steel, depending on the environment.

镀铝锌主要用于保护易生锈的铁基合金。与纯镀锌钢相比，镀铝锌钢的耐腐蚀性更强，因为锌铝合金能保护底层钢材免受环境侵蚀，同时锌还能与接触的钢发生反应，实现自我修复。这一点与镀锌钢类似。

镀铝锌是在热浸工艺中应用于金属的材料，因此，镀铝锌钢卷的厚度与热浸镀锌钢卷的厚度相似。涂层厚度会因基材而异，热浸涂层厚度约为 1 密耳。在同等涂层厚度下，镀铝锌钢的使用寿命通常会比镀锌钢更长，具体取决于所处环境。
