).补充：“镀55%铝锌钢卷”之铝锌合金结构是由55%铝、43.4%锌与1.6%矽在600C高温下固化而组成， 其整个结构由铝铁矽锌，形成致密的四元结晶体，此结晶体在钢板上形成一层屏障， 因而有效的防止腐蚀因子穿透。镀锌钢卷镀锌钢卷因表面被覆锌层阻隔大气的侵蚀，以防止底材继续腐蚀，及确保底材的使用寿命。镀锌钢卷还具有经济性与多样性，可符合不同环境，不同用途之要求，提供高附加价值之产品组合， 无论在精密仪器、资讯、电器、建筑、烤漆等领域都已普遍采用镀锌钢卷。特性耐腐蚀性“镀55%铝锌钢卷”的耐腐蚀性来自铝的障碍层保护功能，和锌的牺牲性保护功能。当锌在切边、刮痕及镀层擦伤部份作牺牲保护时，铝便形成不能溶解的氧化物层，发挥屏障保护功能。镀铝锌合金钢卷已在各种不同大气环境中，进行了20多年的室外曝露试验，证实镀55%铝锌钢板的切边保护功能，比镀锌钢板及镀5%铝锌钢板为佳。耐热性镀55%铝锌合金钢板之耐热性比镀锌钢板佳，与镀铝钢板之抗高温氧化性类似。镀铝锌合金钢板可用于315C的高温环境。反射性镀55%铝锌合金钢板具有高度反射率，使其成为抗热的屏障。用途建筑材料楼承板、天花板、阳台、仓库、屋顶、隔间、墙壁、遮阳天篷、导水天沟、风管工程、地下渠道、导管、 通气管、室内装饰、铁卷
