Introduction to the classification and use of galvanized sheet.

镀锌钢板按生产工艺可分为以下几类：

Galvanized steel sheet according to the production process can be divided into the following categories:

1、热镀锌钢板。将钢板浸入熔融锌浴中以将镀锌钢板粘附到表面。目前主要采用连续镀锌工艺生产，即将成卷的钢板连续浸入镀槽中，锌在镀槽中熔化形成镀锌钢板。

1.Hot dip galvanized steel sheet. The steel sheet is immersed in a molten zinc bath to adhere a zinc-plated steel sheet to the surface. At present, it is mainly produced by a continuous galvanizing process, that is, a coiled steel plate is continuously immersed in a plating tank in which zinc is melted to form a galvanized steel sheet.

2. 合金镀锌钢板。这种钢板也是采用热浸法来生产，但是在取出后，立即将其加热到大约500℃，以形成锌和铁的合金涂层。这种镀锌板具有良好的涂层附着力和焊接性。

2.Alloyed galvanized steel sheet. This steel sheet is also produced by hot dip, but immediately after it is taken out, it is heated to about 500 ° C to form an alloy coating of zinc and iron. This galvanized sheet has good adhesion and weldability of the coating.

3.电镀锌钢板。通过电镀生产这种镀锌钢板具有良好的可加工性。但镀层较薄，耐蚀性不如热镀锌板。

3.Electro-galvanized steel plate. The production of such a galvanized steel sheet by electroplating has good workability. However, the coating is thinner and the corrosion resistance is not as good as that of hot dip galvanized sheet.

4.单面电镀和双面差镀锌钢板。单面镀锌钢板，即只在一侧镀锌的产品。在焊接、喷漆、防锈处理和加工方面比双面镀锌板具有更好的适应性。为了克服一侧未镀锌的缺点，有一种在另一侧镀有薄薄一层锌的镀锌板，即双面差镀锌板。

4.Single-sided plating and double-sided differential galvanized steel. Single-sided galvanized steel, that is, a product that is only galvanized on one side. It has better adaptability than double-sided galvanized sheet in welding, painting, anti-rust treatment and processing. In order to overcome the shortcomings of uncoated zinc on one side, there is a galvanized sheet coated with a thin layer of zinc on the other side, that is, a double-sided differential galvanized sheet.

5.合金、复合镀锌钢板。它由锌和其他金属，如铅、锌合金甚至复合镀钢制成。这种钢板具有优良的防锈性能和良好的涂层性能。

5.Alloy, composite galvanized steel sheet. It is made of zinc and other metals such as lead, zinc alloy or even composite plated steel. This steel plate has excellent rust resistance and good coating properties.

除上述五种外，还有彩色镀锌钢板、印刷镀锌钢板、聚氯乙烯层压镀锌钢板等。然而，最常用的仍然是热浸镀锌板。

In addition to the above five types, there are also colored galvanized steel sheets, printed galvanized steel sheets, and polyvinyl chloride laminated galvanized steel sheets. However, the most commonly used ones are still hot dip galvanized sheets.

镀锌钢板又可分为通用型、屋面型、建筑外墙板型、结构型、瓦板型、拉伸型和深冲型镀锌钢板。

Galvanized steel sheets can be further divided into galvanized steel sheets for general use, roofing, exterior panels for buildings, structural, tiled slabs, tensile and deep drawing.
