一般將成型用鍍鋅鋼板分成一般質(zhì)量、沖壓質(zhì)量、深沖質(zhì)量與超深沖質(zhì)量等四種。JIS G3302在1987年將沖壓質(zhì)量稱(chēng)為SGCD，且區(qū)分為三級(jí)，第一級(jí)SGCD1、第二級(jí)SGCD2及第三級(jí)SGCD3。而ASTM在1994年將分散為A526 CQ、 A527 LFQ、 A528DQ、A642 DQSK與A446 SQ合并成為人STM A653。

Generally, the galvanized steel plate is divided into four kinds: general quality, stamping quality, deep flushing quality and ultra-deep flushing quality. JIS G3302 In 1987, the stamping quality was called SGCD, and it was divided into three levels, SGCD 1, SGCD 2 and SGCD 3. ASTM merged in 1994, integrating A526 CQ, A527 LFQ, A528DQ, A642 DQSK and A446 SQ into human STM A653.

熱鍍鋅鋼板均以建材、輕工、農(nóng)業(yè)、交通等行業(yè)為主要用戶(hù)。由于受現(xiàn)有熱鍍鋅設(shè)備條件、工藝技術(shù)及原板性能的限制，實(shí)際生產(chǎn)可供汽車(chē)制造業(yè)使用的鍍鋅板很少。鍍鋅鋼板的特點(diǎn)：鍍鋅能有效的防治鋼材腐蝕，延長(zhǎng)使用壽命。鍍鋅薄鋼板（厚度為0.4～1.2mm）又稱(chēng)鍍鋅鐵皮，俗稱(chēng)白鐵皮。鍍鋅鋼板廣泛應(yīng)用于建筑、車(chē)輛、家電、日用品等行業(yè)。

Hot-dip galvanized steel plate are building materials, light industry, agriculture, transportation and other industries as the main users. Due to the limitation of the existing hot dip galvanizing equipment conditions, technology and performance of the original plate, the actual production of galvanized sheet can be used in the automobile manufacturing industry. Characteristics of galvanized steel plate: galvanized steel can effectively prevent steel corrosion and prolong the service life. Galvanized sheet steel plate (thickness of 0.4~1.2mm) is also known as galvanized iron skin, commonly known as white iron sheet. Galvanized steel plate is widely used in construction, vehicles, home appliances, daily necessities and other industries.

雙面鍍鋅高強(qiáng)度鋼板能保證長(zhǎng)久防銹，強(qiáng)度不會(huì)隨使用時(shí)間的延長(zhǎng)而降低。目前大多數(shù)自主品牌采用的都是單面鍍鋅鋼板，其耐腐蝕度和強(qiáng)度都低于雙面鍍鋅高強(qiáng)度鋼板。相對(duì)于普通碳素結(jié)構(gòu)鋼板，高強(qiáng)度鋼板擁有更好的強(qiáng)度和延展性，抗動(dòng)態(tài)沖擊特性也更優(yōu)秀，同時(shí)，雙面鍍鋅鋼板相當(dāng)于有了一層防護(hù)膜，延長(zhǎng)耐腐蝕的時(shí)間。

Double-sided galvanized high-strength steel plate can guarantee long-term rust prevention, and the strength will not decrease with the extension of use time. At present, most of the independent brands use single-sided galvanized steel plate, its corrosion resistance and strength are lower than that of double-sided galvanized high strength steel plate. Compared with ordinary carbon structural steel plate, high strength steel plate has better strength and ductility, and better dynamic impact resistance. At the same time, double-sided galvanized steel plate is equivalent to a layer of protective film, which extends the corrosion resistance time.
