彩鋼板涂層是冷軋鋼板、鍍鋅鋼板，進行表面化學處理后涂敷（輥涂）或復合有機薄膜（PVC膜等），再經烘烤固化而制成的產品。也有人把這種產品稱之為“預輥涂彩鋼板”。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涂料對于材質有良好的附著性，彩涂鋼板易于加工成型，價廉且產品多，顏色和光澤的選擇余地大。聚酯涂料對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重的地區或需多次成型加工的產品。 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.
