鍍鋅板價格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。南岸鍍鋅板電鍍(du)鋅(xin)成本(ben)低，表(biao)面不(bu)是很光(guang)滑，其(qi)本(ben)身的(de)耐(nai)腐蝕性(xing)比(bi)熱鍍(du)鋅(xin)管相差很多。提(ti)起鍍(du)鋅(xin)管，可(ke)能沒接觸過建材的(de)朋友并不(bu)了解。從1935年建立一條連續涂(tu)層鋼(gang)(gang)板線開始，彩涂(tu)板得到(dao)了廣泛應(ying)用，目前彩涂(tu)板的(de)品種繁多，大約超過600種，彩涂(tu)板兼(jian)有(you)(you)機(ji)聚合物與鋼(gang)(gang)板兩(liang)者的(de)優點，既有(you)(you)有(you)(you)機(ji)聚合物的(de)良好著色性(xing)、成型性(xing)、耐(nai)蝕性(xing)、裝飾性(xing)、又有(you)(you)鋼(gang)(gang)板的(de)高強(qiang)度和易加工性(xing)，能很容易地進行沖壓裁(cai)剪、彎曲、深(shen)沖等加工。

彩(cai)(cai)(cai)鋼(gang)(gang)是(shi)指(zhi)彩(cai)(cai)(cai)涂(tu)鋼(gang)(gang)板(ban)(ban)(ban)，彩(cai)(cai)(cai)涂(tu)鋼(gang)(gang)板(ban)(ban)(ban)是(shi)一種帶有有機(ji)涂(tu)層的鋼(gang)(gang)板(ban)(ban)(ban)，傳統的涂(tu)層分好幾(ji)類，氟(fu)碳(tan)涂(tu)層的，幾(ji)乎可(ke)以(yi)(yi)防腐20年。一般從(cong)鋼(gang)(gang)廠以(yi)(yi)卷筒的形(xing)式分銷到各地。我們經常看到的彩(cai)(cai)(cai)鋼(gang)(gang)板(ban)(ban)(ban)是(shi)指(zhi)加(jia)工(gong)好的板(ban)(ban)(ban)材，厚度(du)在50~100mm左右，它是(shi)由中間的填料(liao)和兩(liang)面的彩(cai)(cai)(cai)鋼(gang)(gang)板(ban)(ban)(ban)組(zu)成。其中，彩(cai)(cai)(cai)板(ban)(ban)(ban)厚度(du)有0.4mm、0.5mm、0.6mm等不同的厚度(du),中間層可(ke)以(yi)(yi)是(shi)聚胺脂、巖綿或(huo)泡沫塑料(liao)等。由于有專用型(xing)材，所(suo)以(yi)(yi)用彩(cai)(cai)(cai)鋼(gang)(gang)板(ban)(ban)(ban)構(gou)筑的廠房建(jian)造速度(du)很(hen)快(kuai)（如非典時的小(xiao)湯(tang)山(shan)醫(yi)院(yuan)），但(dan)強度(du)低。
