有花镀锌彩钢板介绍

1有花镀锌彩钢板包装分为镀锌钢板定尺包装和镀锌钢板卷装两种。一般用白铁皮包装，内衬防潮纸，外面用铁腰扎起来，防止内部镀锌钢板摩擦
2 有花镀锌彩钢板规范、型号和规范相关材料限值（如以下和）表示镀锌钢板的推荐极限厚度、长度、总宽度和允许问题。此外，还可根据客户要求指定纸板的总宽度和长度以及卷的总宽度。

1. The package is divided into two kinds: galvanized steel sheet cut into fixed length and galvanized steel sheet package with coil. Generally, it is packed with white iron sheet, lined with moisture-proof paper, and tied with iron waist outside to prevent friction between galvanized steel plates inside

2. Specifications, models and specifications related material limits (such as the following and) indicate the recommended limit thickness, length, total width and allowable problems of galvanized steel sheet. In addition, the total width and length of the board and the total width of the roll can also be specified according to the customer's request.
3. Overview of surface layer: due to the contradiction of treatment methods in coating process of galvanized steel sheet, the general situation is also contradictory, such as general zinc, fine zinc, flat zinc, no zinc and phosphating treatment. The galvanized steel sheet and coil cut into fixed length shall not have defects harmful to the application (described below). However, the steel coil is allowed to have welding position and so on.
4. Hot dip galvanizing quantity limit value of hot dip galvanizing amount: hot dip galvanizing amount is an effective method to listen to opinions generally, which implies the thickness of zinc coating of galvanized steel sheet. There are two kinds of double-sided hot-dip galvanizing, i.e. equal thickness hot-dip galvanizing, and double-sided hot-dip galvanizing quantity contradiction (namely differential thickness galvanizing). The module with hot galvanizing amount is g / m2.
5. Equipment function
(1) Compressive strength test: Generally speaking, if reasonable layout, drawing and deep drawing of galvanized steel sheet have compressive strength function request.
(2) Bending test: it is a key category to measure the processing function of sheet metal. However, the appeal of various countries to various galvanized steel plates is actually different. Generally, after the galvanized steel sheet is bent for 180o, the zinc layer on both sides shall not leave, and the plate foundation shall not have cracking and cracking.
6. The request of composition to the composition of hot-dip galvanized steel sheet is contradictory to the limit of various countries. If Japan does not entreat, Britain does. Generally, no product inspection was carried out.
7. There are two general goals for shape measurement, i.e. verticality and long knife bending. It is necessary to divide the vertical degree of plate and the larger allowable limit of long knife bending.
The pattern of galvanized steel plate is printed on the surface of galvanized steel plate. The appearance looks very bright and good-looking. It is generally used as a household appliance case and plastic bucket. There are no lines on the surface of Begonia galvanized steel sheet, which can't compare with the bright and dark color of hot-dip galvanized steel sheet, which is similar to cold-rolled steel sheet. There is no difference in the characteristics of flowering Begonia, mainly appearance.
