电镀锌SECC
宝山钢铁股份有限公司生产的厚度为0.30mm～2.0mm的连续电镀锌/锌镍合金钢板及钢带，以下简称钢板及钢带。其表面颜色多种，例如：SECCN5呈淡蓝色。宝钢规定订货中未注明尺寸及不平度精度、表面质量级别、表面处理种类及包装方式，则以尺寸普通精度、不平度普通精度、表面质量级别为FB、表面处理为铬酸钝化处理，并按供方指定的包装方式供货。对等厚镀层，镀层重量每面三点试验平均值应不小于相应面公称镀层重量，单点试验值不小于相应面公称镀层重量的85％；对差厚及单面镀层，镀层重量每面三点试验平均值应不小于相应面公称镀层重量，单点试验值不小于相应面公称镀层重量的80％。使用本产品时，用户应根据其加工工艺、涂漆方法、涂漆设备等情况选择合适的表面处理方式，并尽量缩短本产品的储存时间。选择合适的表面处理可减轻运输和储存过程中产生白锈的倾向，同时能够改善涂漆层的粘附性，对镀层起保护作用。对后道加工工序需磷化和喷漆的，不推荐选择铬酸钝化处理方式。
Electric galvanized sheet SECC
Baoshan iron and steel co., LTD. Production of thickness from 0.30 mm to 0.30 mm continuous nickel/zinc alloy steel sheet and galvanized steel strip, hereinafter referred to as the steel plate and steel belt. The surface color of kinds, such as: SECCN5 are light blue. Baosteel rules not specified in the order size and roughness level of precision, surface quality, surface treatment type and packing, with common size precision, roughness average precision, surface quality level for the FB and surface treatment of chromate passivation treatment, and the way of packing supplier specified by the supplier. Equivalent thick coating, the coating weight each three corresponding nominal surface coating test should not be less than the average weight, single point test value is not less than 85% by weight of the corresponding nominal surface coating; For different thickness and single coating, the coating weight each three corresponding nominal surface coating test should not be less than average weight, single point test value is not less than 80% by weight of the corresponding nominal surface coating. When using this product, the user should be based on its process, coating methods, coating equipment, and so on and so forth to choose the right means of surface treatment, and try to shorten the storage time of this product. To choose the appropriate surface treatment can reduce tend to produce white rust during transportation and storage, at the same time can improve the adhesion of the coating layer, the protective coatin
