全国彩涂镀锌板的基板分类代号

目前,彩涂镀锌板主要应用于建筑业,也涉及汽车、板材等行业。由于其优良的性质,良好的耐腐蚀性,被广泛应用。在选择的时候,也要明确型号的选择,不同型号的产品性能也不同。下面介绍底板的分类代号。

1结构分类代号:z—普通锌片:按正常冷却速率结晶而成,可用于一般用途:x—小尺寸锌片:特殊控制冷却速度后,锌片尺寸小于普通锌花,适用于一般锌花不能满足要求的涂装等场合;GZ精整锌花:小锌花经精整加工而成,适用于拉深和超深拉深加工及表面粗糙度要求低的场合。
2彩涂镀锌板加工性能代号:Pt通用,JY机械咬合,SC拉深,CS超拉深,JY结构。选购时一定要注意使用。
三。彩涂镀锌板镀锌层重量代号:Z100、z200、z275;镀锌层重量是指钢板两侧的总锌含量,以每平方米彩色镀锌板的锌含量(g/m2)表示,如Z100表示其锌含量不低于100g/m2。
标记示例:镀锌层重量275g/m2,可加工性JY,表面结构Z,表面处理y,尺寸精度B,钢板长×宽×高0.70mm×700mm×2000mm标记为:钢板:275-JY-Z-y-B-0.70×700×2000-gb2518-81。

At present, color coated galvanized sheet is mainly used in the construction industry, and it is also involved in the automobile and plate industry. Due to its excellent nature, good corrosion resistance, it is widely used. When selecting, we should also make clear the model selection, and the performance of different models of products is also different. Here is to introduce the classification code of base plate.

1. Structure classification code: z-normal zinc flake: it is obtained by crystallization according to normal cooling rate, which can be used for general purpose: x-small-sized zinc flake: the size of zinc flake is smaller than that of normal zinc flower after special control of cooling rate, which is suitable for painting and other occasions where the normal zinc flower can not meet the requirements; GZ finishing zinc flower: small zinc flower is processed by finishing, which is suitable for deep drawing and ultra deep drawing processing and surface roughness requirements Low occasion.
2. Processing performance code: Pt general purpose, JY mechanical bite, SC deep drawing, CS ultra deep drawing, JY structure. When choosing, be sure to pay attention to the use.
3. Zinc coating weight code: Z100, z200, z275; zinc coating weight refers to the total zinc content on both sides of the steel plate, expressed in grams of zinc per square meter of color coated galvanized sheet (g / m2), for example, Z100 means its zinc content is not less than 100g / m2.
Marking example: zinc coating weight 275g / m2, processability JY, surface structure Z, surface treatment y, dimensional accuracy B, steel plate with length × width × height of 0.70mm × 700mm × 2000mm is marked as: steel plate: 275-jy-z-y-b-0.70 × 700 × 2000-gb2518-81.
