用電鍍(du)(du)(du)(du)(du)(du)(du)法制造這(zhe)種(zhong)(zhong)鍍(du)(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)具(ju)有良好的(de)加(jia)工性(xing)。但(dan)鍍(du)(du)(du)(du)(du)(du)(du)層(ceng)較薄，耐(nai)腐蝕性(xing)不如熱(re)浸(jin)法鍍(du)(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)；單(dan)(dan)面(mian)鍍(du)(du)(du)(du)(du)(du)(du)和雙(shuang)(shuang)面(mian)差(cha)鍍(du)(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。單(dan)(dan)面(mian)鍍(du)(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)，即只在(zai)一面(mian)鍍(du)(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)的(de)產品。在(zai)焊接、涂(tu)(tu)(tu)裝(zhuang)、防銹處理、加(jia)工等(deng)方面(mian)，具(ju)有比雙(shuang)(shuang)面(mian)鍍(du)(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)好的(de)適應性(xing)。為(wei)克服單(dan)(dan)面(mian)未(wei)涂(tu)(tu)(tu)鋅(xin)(xin)(xin)(xin)的(de)缺點，又有一種(zhong)(zhong)在(zai)另面(mian)涂(tu)(tu)(tu)以薄層(ceng)鋅(xin)(xin)(xin)(xin)的(de)鍍(du)(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)，即雙(shuang)(shuang)面(mian)差(cha)鍍(du)(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)；合金(jin)、復合鍍(du)(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。它是(shi)用鋅(xin)(xin)(xin)(xin)和其(qi)他金(jin)屬如鉛(qian)、鋅(xin)(xin)(xin)(xin)制成合金(jin)乃至復合鍍(du)(du)(du)(du)(du)(du)(du)成的(de)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。這(zhe)種(zhong)(zhong)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)既具(ju)有防銹性(xing)能，又有良好的(de)涂(tu)(tu)(tu)裝(zhuang)性(xing)能。 除上述五種(zhong)(zhong)外，還有彩色鍍(du)(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)、印花(hua)涂(tu)(tu)(tu)裝(zhuang)鍍(du)(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)、聚氯(lv)乙烯疊層(ceng)鍍(du)(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)等(deng)。但(dan)目(mu)前常用的(de)仍為(wei)熱(re)浸(jin)鍍(du)(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)。 鍍(du)(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)按用途又可分為(wei)一般(ban)用、屋頂(ding)用、建(jian)筑(zhu)外側(ce)板(ban)(ban)(ban)(ban)(ban)用、結構用、瓦壟板(ban)(ban)(ban)(ban)(ban)用、拉伸(shen)用和深沖用等(deng)鍍(du)(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。

熱鍍(du)鋅(xin)生(sheng)產發展一(yi)直(zhi)(zhi)處(chu)于滯(zhi)后狀態。20世(shi)(shi)紀(ji)50年(nian)(nian)(nian)(nian)代(dai)到60年(nian)(nian)(nian)(nian)代(dai)陸續建成(cheng)了(le)13條單(dan)張鋼(gang)板熔劑法(fa)熱鍍(du)鋅(xin)機(ji)組(zu)，能力為10萬t/a，但因產量低、成(cheng)本高(gao)、質(zhi)量差(cha)、污染環境、經濟(ji)(ji)效益差(cha)等缺陷已先后停(ting)、轉產。從20世(shi)(shi)紀(ji)70年(nian)(nian)(nian)(nian)代(dai)末，我國才(cai)開始(shi)建造大型(xing)寬帶熱鍍(du)鋅(xin)機(ji)組(zu)。熱鍍(du)鋅(xin)帶鋼(gang)在(zai)我國市場一(yi)直(zhi)(zhi)是緊缺品(pin)種。從20世(shi)(shi)紀(ji)90年(nian)(nian)(nian)(nian)代(dai)中期以來，每年(nian)(nian)(nian)(nian)都要從國外進口80-100萬t左右(you)。隨著國內經濟(ji)(ji)的(de)發展，尤其是汽車、家(jia)電及建筑業的(de)發展，對(dui)鍍(du)鋅(xin)帶鋼(gang)的(de)需(xu)求量也大大增加。

鍍(du)鋅(xin)卷分熱鍍(du)鋅(xin)和電鍍(du)鋅(xin)兩種，熱鍍(du)鋅(xin)鍍(du)鋅(xin)層厚，具有(you)鍍(du)層均(jun)勻，附著力強，使(shi)用壽(shou)命長等(deng)優點。電鍍(du)鋅(xin)成本低，表面不(bu)是很(hen)光滑，其本身(shen)的(de)(de)(de)耐腐蝕(shi)性(xing)(xing)比(bi)熱鍍(du)鋅(xin)管相差很(hen)多。提(ti)起鍍(du)鋅(xin)管，可(ke)能(neng)沒接觸(chu)過建(jian)材的(de)(de)(de)朋友并(bing)不(bu)了(le)解。從(cong)1935年(nian)建(jian)立一條連續涂(tu)層鋼(gang)板(ban)(ban)線開始(shi)，彩涂(tu)板(ban)(ban)得(de)到(dao)了(le)廣(guang)泛應用，目前彩涂(tu)板(ban)(ban)的(de)(de)(de)品種繁(fan)多，大約(yue)超(chao)過600種，彩涂(tu)板(ban)(ban)兼有(you)機聚(ju)合(he)物與鋼(gang)板(ban)(ban)兩者的(de)(de)(de)優點，既(ji)有(you)有(you)機聚(ju)合(he)物的(de)(de)(de)良(liang)好(hao)著色性(xing)(xing)、成型性(xing)(xing)、耐蝕(shi)性(xing)(xing)、裝飾性(xing)(xing)、又(you)有(you)鋼(gang)板(ban)(ban)的(de)(de)(de)高強度和易加(jia)工(gong)性(xing)(xing)，能(neng)很(hen)容易地進行沖壓裁(cai)剪、彎(wan)曲、深沖等(deng)加(jia)工(gong)。

熱鍍鋅廠家鍍鋅方管是一種具以熱軋或冷軋鍍鋅帶鋼或鍍鋅卷板為坯料經冷彎曲加工成型后再經高頻焊接制成的方形截面形狀尺寸的空心方形的截面型鋼鋼管；鍍鋅卷或將事先做好的冷彎空心型鋼管再經熱浸鍍鋅加工而成的鍍鋅方矩管。遂寧熱鍍鋅鍍(du)(du)(du)(du)(du)鋅量是(shi)表示(shi)鍍(du)(du)(du)(du)(du)鋅板鋅層厚度的一個(ge)普(pu)遍采用的有效方法。鍍(du)(du)(du)(du)(du)鋅量的單位為(wei)g/m2。鍍(du)(du)(du)(du)(du)鋅層通過鈍化處(chu)(chu)(chu)理(li)，可減少潮溫貯運條件下產生折銹蝕(白銹) 。但(dan)這種(zhong)化學處(chu)(chu)(chu)理(li)的防(fang)腐蝕性能是(shi)有限的，而(er)且，妨(fang)礙大多(duo)數涂(tu)料的附(fu)著性。這種(zhong)處(chu)(chu)(chu)理(li)一般不(bu)用在(zai)鋅鐵(tie)合金(jin)鍍(du)(du)(du)(du)(du)層，除光整表面(mian)外(wai)，作為(wei)常規，生產廠對(dui)其他類型的鍍(du)(du)(du)(du)(du)鋅層均(jun)進(jin)行鈍化處(chu)(chu)(chu)理(li)。
