C型鋼廠家鍍鋅卷分熱鍍鋅和電鍍鋅兩種，熱鍍鋅鍍鋅層厚，具有鍍層均勻，附著力強，使用壽命長等優點。萬州C型鋼電鍍(du)鋅成本低(di)，表面不(bu)是很(hen)光滑，其本身的耐腐蝕(shi)性比熱鍍(du)鋅管(guan)相(xiang)差很(hen)多。提起鍍(du)鋅管(guan)，可能沒接觸過建材的朋友并不(bu)了解。從1935年建立一條連續涂(tu)(tu)層鋼板(ban)線開始，彩涂(tu)(tu)板(ban)得到(dao)了廣泛應用，目(mu)前彩涂(tu)(tu)板(ban)的品種繁多，大(da)約(yue)超過600種，彩涂(tu)(tu)板(ban)兼(jian)有(you)機聚(ju)合物(wu)(wu)與鋼板(ban)兩者的優點，既有(you)有(you)機聚(ju)合物(wu)(wu)的良(liang)好著(zhu)色性、成型性、耐蝕(shi)性、裝飾性、又有(you)鋼板(ban)的高強度和易加(jia)(jia)工性，能很(hen)容(rong)易地進行沖(chong)壓裁剪、彎(wan)曲、深沖(chong)等加(jia)(jia)工。

鍍(du)(du)鋅(xin)方(fang)管是(shi)一種(zhong)具以熱軋或冷軋鍍(du)(du)鋅(xin)帶(dai)鋼或鍍(du)(du)鋅(xin)卷板為坯(pi)料經冷彎(wan)曲(qu)加工成型后再(zai)經高頻焊接制成的(de)(de)(de)(de)方(fang)形截(jie)面(mian)形狀尺(chi)寸的(de)(de)(de)(de)空心(xin)方(fang)形的(de)(de)(de)(de)截(jie)面(mian)型鋼鋼管；鍍(du)(du)鋅(xin)卷或將(jiang)事(shi)先(xian)做(zuo)好(hao)的(de)(de)(de)(de)冷彎(wan)空心(xin)型鋼管再(zai)經熱浸鍍(du)(du)鋅(xin)加工而(er)成的(de)(de)(de)(de)鍍(du)(du)鋅(xin)方(fang)矩管。鍍(du)(du)鋅(xin)量是(shi)表(biao)示鍍(du)(du)鋅(xin)板鋅(xin)層(ceng)(ceng)厚度的(de)(de)(de)(de)一個(ge)普(pu)遍(bian)采用(yong)的(de)(de)(de)(de)有效方(fang)法。鍍(du)(du)鋅(xin)量的(de)(de)(de)(de)單位為g/m2。鍍(du)(du)鋅(xin)層(ceng)(ceng)通過鈍化(hua)處理，可減少潮溫貯(zhu)運條件下產(chan)生(sheng)(sheng)折(zhe)銹(xiu)蝕(shi)(shi)(白銹(xiu)) 。但這種(zhong)化(hua)學處理的(de)(de)(de)(de)防腐蝕(shi)(shi)性能是(shi)有限的(de)(de)(de)(de)，而(er)且，妨礙大(da)多數涂料的(de)(de)(de)(de)附著性。這種(zhong)處理一般不用(yong)在鋅(xin)鐵合金(jin)鍍(du)(du)層(ceng)(ceng)，除光(guang)整表(biao)面(mian)外，作為常規，生(sheng)(sheng)產(chan)廠對其他(ta)類型的(de)(de)(de)(de)鍍(du)(du)鋅(xin)層(ceng)(ceng)均進(jin)行鈍化(hua)處理。
