建筑（屋顶和外墙板）的材料要求可分为安全性能（抗震、抗风、防火）、居住性能（防水、隔热、隔音）、耐久性（抗污染、耐候、美观）、生产加工（经济、易于加工，易于维护）。

安全和使用寿命对建筑物的最终所有者至关重要。对于设计单位来说，使用寿命、承载力、外观等更为重要。对于建筑墙体和屋顶成型处理器，彩色涂层面板的可加工性（表面硬度、耐磨性、形状和钢板强度）是首选要求。
当然，彩涂板的质量主要取决于彩涂板的生产厂家，但如果加工安装设备和方法不当，最终产品的外观和使用寿命将受到不同程度的损害。
[彩色涂层板的性能指标是什么？
基材：屈服强度、拉伸强度、延伸率
涂层：涂层重量、附着力
涂层：色差、光泽度、T弯、冲击、硬度、抗粉末性、耐湿热性。
表面：肉眼可见的表面缺陷等。

平面度：公差、不平等

The material requirements of building (roof and exterior wall panels) can be divided into safety performance (earthquake resistance, wind resistance, fire resistance), residential performance (waterproof, heat insulation, sound insulation), durability (pollution resistance, weather resistance, beauty), production and processing (economy, easy processing, easy maintenance).
Safety and service life are critical to the ultimate owner of the building. For design units, service life, bearing capacity, appearance and so on are more important. For building wall and roof forming processors, machinability (surface hardness, wear resistance, shape and steel plate strength) of color coated panels is the preferred requirement.
Of course, the quality of color coated sheet mainly depends on the manufacturer of color coated sheet, but if the processing and installation equipment and methods are inappropriate, the appearance and service life of the final product will be damaged to varying degrees.
[What are the performance indicators of color coated sheets?
Substrate: Yield Strength, Tensile Strength, Elongation
Coating: Coating weight, adhesion
Coating: color difference, gloss, T bending, impact, hardness, powder resistance, moisture and heat resistance.
Surface: Surface defects visible to the naked eye, etc.
Flatness: Tolerance, Inequality
