彩涂镀锌板因其尺寸规格备受欢迎

彩色镀锌板是指表面有一层锌的钢板。镀锌是一种经济实用的防腐方法。全世界约一半的锌生产用于这一过程。镀锌钢板涂锌金属,以防腐蚀,延长使用寿命。这种镀锌钢板叫做彩色镀锌钢板.

彩色镀锌板的推荐厚度、长度和宽度及其误差在有关产品规范中有规定。一般来说,彩涂镀锌板越厚,允许误差越大,而不是固定的0.02-0.04mm。厚度误差根据屈服强度、拉伸系数等也有不同的要求。长宽误差5mm,板厚0.4~3.2
外观:外观:由于涂装过程中处理方法的不同,彩涂镀锌板的外观也不同,如普通锌花、细锌花、平锌花、非锌花和磷化处理。德国的规范也有等级制度。

彩色镀锌板外观应突出,不应有任何不利于产品使用的缺陷,如无镀层、孔洞、裂纹和浮渣、镀层厚度以外的划痕、铬酸粉尘、白锈等。在国外代码中非常清楚。订货时应在合同中说明不足之处。镀锌量标准值:镀锌量是表示镀锌板厚度的有效方法。镀锌量为g/m2。

.Coloured galvanized sheet refers to steel sheet with a layer of zinc on its surface. Galvanizing is an economical and practical anticorrosion method. About half of the world's zinc production is used in this process. Galvanized steel sheet is coated with zinc metal to avoid corrosion and prolong its service life. This kind of galvanized steel sheet is called color galvanized steel sheet.
The recommended thickness, length and width of color-coated galvanized sheets and their errors are stipulated in relevant product specifications. Generally speaking, the thicker the color-coated galvanized sheet, the greater the allowable error, rather than the fixed 0.02-0.04 mm. Thickness error also has different requirements according to yield strength, tensile coefficient and so on. The error of length and width is 5 mm, and the thickness of plate is between 0.4 and 3.2.
Appearance: Appearance: Due to the different treatment methods in the painting process, the appearance of color-coated galvanized sheet is different, such as ordinary zinc flower, fine zinc flower, flat zinc flower, non-zinc flower and phosphating treatment. German norms also have a hierarchical appearance.
The coloured galvanized sheet should have a prominent appearance and should not have any defects harmful to the use of the product, such as no coating, holes, cracks and scum, scratches beyond the thickness of the coating, chromic acid dust, white rust, etc. Detailed rules on appearance defects are very clear in foreign codes. Deficiencies should be specified in the contract when ordering. Standard Value of Galvanized Quantity: Galvanized Quantity is an effective method to indicate the thickness of galvanized sheet. The galvanizing quantity is g/m2.
