一般将成型用镀锌钢板分成一般质量、冲压质量、深冲质量与超深冲质量等四种。JIS G3302在1987年将冲压质量称为SGCD，且区分为三级，第一级SGCD1、第二级SGCD2及第三级SGCD3。而ASTM在1994年将分散为A526 CQ、 A527 LFQ、 A528DQ、A642 DQSK与A446 SQ合并成为人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.

热镀锌钢板均以建材、轻工、农业、交通等行业为主要用户。由于受现有热镀锌设备条件、工艺技术及原板性能的限制，实际生产可供汽车制造业使用的镀锌板很少。镀锌钢板的特点：镀锌能有效的防治钢材腐蚀，延长使用寿命。镀锌薄钢板（厚度为0.4～1.2mm）又称镀锌铁皮，俗称白铁皮。镀锌钢板广泛应用于建筑、车辆、家电、日用品等行业。

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.

双面镀锌高强度钢板能保证长久防锈，强度不会随使用时间的延长而降低。目前大多数自主品牌采用的都是单面镀锌钢板，其耐腐蚀度和强度都低于双面镀锌高强度钢板。相对于普通碳素结构钢板，高强度钢板拥有更好的强度和延展性，抗动态冲击特性也更优秀，同时，双面镀锌钢板相当于有了一层防护膜，延长耐腐蚀的时间。

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.
