镀铝锌彩涂板是近年来国内由于高端应用而产生的新型材料，常用CCLI指代。是由较镀锌更具耐腐蚀性能的镀铝锌钢板（55％铝、43%锌与1.6％硅）作为基板经过表面脱脂、磷化、络酸盐处理后，涂上有机涂料经烘烤而制成的产品。
实验表明，镀铝锌彩涂板（AZ150,G345A,PVDF）非常适用于极端环境下的建筑或其他设施，极具耐蚀和耐气候性，且此种钢板各大钢厂均可保证20年以上的使用寿命。另外高强度钢板在国外已普遍使用，具有较好的经济性，也是国内的发展趋势。
Aluminum zinc color coated plate is a new material produced due to high-end applications in China in recent years, which is commonly referred to as CCLI. It is a product made of aluminum zinc plated steel plate (55% aluminum, 43% zinc and 1.6% silicon) with more corrosion resistance than zinc plating as the substrate, after surface degreasing, phosphating and complex acid salt treatment, coated with organic coating and baked.
Experiments show that the aluminum zinc color coated plate (az150, g345a, PVDF) is very suitable for buildings or other facilities in extreme environments, with great corrosion resistance and climate resistance, and the major steel mills can guarantee the service life of this kind of steel plate for more than 20 years. In addition, high-strength steel plate has been widely used abroad, which has good economy and is also the development trend in China.
