彩鋼板涂層是冷軋鋼板、鍍鋅鋼板，進(jìn)行表面化學(xué)處理后涂敷（輥涂）或復(fù)合有機(jī)薄膜（PVC膜等），再經(jīng)烘烤固化而制成的產(chǎn)品。也有人把這種產(chǎn)品稱之為“預(yù)輥涂彩鋼板”。目前用于彩色涂層鋼板的涂料種類有聚酯涂層(PE)、氟碳涂層(PVDF)、硅改性涂層(SMP)、高耐侯涂層(HDP)、丙稀酸涂層、聚氨脂涂層(PU)、塑料溶膠涂層(PVC)等。PE涂料對(duì)于材質(zhì)有良好的附著性，彩涂鋼板易于加工成型，價(jià)廉且產(chǎn)品多，顏色和光澤的選擇余地大。聚酯涂料對(duì)耐紫外光性與涂膜耐粉化性，并不理想，因此PE涂料的使用仍需受到一些限制，一般用在空氣污染不嚴(yán)重的地區(qū)或需多次成型加工的產(chǎn)品。

Color steel plate coating is a product made of cold-rolled steel plate, galvanized steel plate, surface chemical treatment after coating (roll coating) or composite organic film (PVC film, etc.), and then after baking and curing products. Some people also call this product "pre-roll coated color steel plate". At present, the types of coatings used for color coating steel plate include polyester coating (PE), fluorocarbon coating (PVDF), silicon modified coating (SMP), high-resistant coating (HDP), propionized acid coating, polyurethane coating (PU), plastic sol coating (PVC), etc. PE coating for the material has a good attachment, color coated steel plate is easy to process and shape, cheap and many products, color and luster choice is large. Polester coating is not ideal for uv resistance and coating resistance, so the use of PE coating still needs to be subject to some restrictions, generally used in the air pollution is not serious areas or need multiple molding processing products.
