（1）冷轧基板

(1) Cold rolled substrate

由冷轧基板生产的彩色板，具有平滑美丽的外观，且具有冷轧板的加工性能；但是表面涂层的任何细小划伤都会把冷轧基 板暴露在空气中，从而使露铁处很快生成红锈。因此这类产品只能用于要求不高的临时隔离措施和作室内用材。

Color plates produced from cold-rolled substrates have a smooth and beautiful appearance, and possess the processing performance of cold-rolled plates; However, any small scratches on the surface coating will expose the cold-rolled substrate to the air, causing the exposed iron to quickly form red rust. Therefore, these types of products can only be used for temporary isolation measures with low requirements and as indoor materials.

（2）热镀锌基板

(2) Hot dip galvanized substrate

把有机涂料涂复在热镀锌钢板上得到的产品即为热镀锌彩涂板。热镀锌彩涂板除具有锌的保护作用外，表面上的有机涂层 还起了隔绝保护、防止生锈的作用，使用寿命比热镀锌板更长。热镀锌基板的含锌量一般为180g/m2（双面），建筑外用热 镀锌基板的镀锌量高为275g/m2。

The product obtained by coating organic coating on hot-dip galvanized steel plate is hot-dip galvanized color coated plate. In addition to the protective effect of zinc, the organic coating on the surface of hot-dip galvanized color coated sheet also provides insulation protection and prevents rust, resulting in a longer service life than hot-dip galvanized sheet. The zinc content of hot-dip galvanized substrates is generally 180g/m2 (double-sided), and the zinc content of hot-dip galvanized substrates for building exteriors is as high as 275g/m2.

（3）热镀铝锌基板

(3) Hot dip aluminum zinc substrate

根据要求，也可以采用热镀铝锌钢板作为彩涂基板（55%AI-Zn和5%AI-Zn）。

According to the requirements, hot-dip aluminum zinc steel plates can also be used as color coated substrates (55% AI Zn and 5% AI Zn).

（4）电镀锌基板

(4) Electroplated galvanized substrate

用电镀锌板为基板，涂上有机涂料烘烤所得的产品为电镀锌彩涂板，由于电镀锌板的锌层薄，通常含锌量为20/20g/m2，因 此该产品不适合使用在室外制作墙、屋顶等。但因具有美丽的外观和优良的加工性能，因此主要可用于家电、音响、钢家 具、室内装璜等。

The product obtained by baking electroplated galvanized sheet with organic coating is electroplated color coated sheet. Due to the thin zinc layer of electroplated sheet, which usually contains 20/20g/m2 of zinc, this product is not suitable for outdoor wall and roof production. However, due to its beautiful appearance and excellent processing performance, it can mainly be used in household appliances, audio systems, steel furniture, interior decoration, etc.
