鍍鋅帶鋼廠家鍍鋅鋼板是為防止鋼板表面遭受腐蝕，延長其使用壽命，在鋼板表面涂以一層金屬鋅，這種涂鋅的薄鋼板稱為鍍鋅板。珠海攀華鍍鋅帶鋼鋼(gang)(gang)板(ban)(ban)也(ye)是用熱浸法制(zhi)造，但(dan)在出槽(cao)后(hou)，立即(ji)把它(ta)加(jia)熱到(dao)500℃左右，使其生(sheng)(sheng)(sheng)成鋅(xin)(xin)(xin)(xin)和(he)(he)鐵的(de)合(he)金(jin)被膜(mo)。這(zhe)種(zhong)(zhong)鍍(du)(du)鋅(xin)(xin)(xin)(xin)卷(juan)具有良好(hao)的(de)涂料(liao)的(de)密著性(xing)和(he)(he)焊接性(xing)。合(he)金(jin)化鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)。這(zhe)種(zhong)(zhong)鋼(gang)(gang)板(ban)(ban)也(ye)是用熱浸法制(zhi)造，但(dan)在出槽(cao)后(hou)，立即(ji)把它(ta)加(jia)熱到(dao)500℃左右，使其生(sheng)(sheng)(sheng)成鋅(xin)(xin)(xin)(xin)和(he)(he)鐵的(de)合(he)金(jin)被膜(mo)。這(zhe)種(zhong)(zhong)鍍(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)具有良好(hao)的(de)涂料(liao)的(de)密著性(xing)和(he)(he)焊接性(xing)。熱浸鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)。將薄鋼(gang)(gang)板(ban)(ban)浸入熔解(jie)的(de)鋅(xin)(xin)(xin)(xin)槽(cao)中，使其表(biao)面(mian)粘附(fu)一(yi)層鋅(xin)(xin)(xin)(xin)的(de)薄鋼(gang)(gang)板(ban)(ban)。目前(qian)主(zhu)要采用連續(xu)(xu)鍍(du)(du)鋅(xin)(xin)(xin)(xin)工藝生(sheng)(sheng)(sheng)產，即(ji)把成卷(juan)的(de)鋼(gang)(gang)板(ban)(ban)連續(xu)(xu)浸在熔解(jie)有鋅(xin)(xin)(xin)(xin)的(de)鍍(du)(du)槽(cao)中制(zhi)成鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)。合(he)金(jin)、復合(he)鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)。它(ta)是用鋅(xin)(xin)(xin)(xin)和(he)(he)其他金(jin)屬如(ru)鉛、鋅(xin)(xin)(xin)(xin)制(zhi)成合(he)金(jin)乃至復合(he)鍍(du)(du)成的(de)鋼(gang)(gang)板(ban)(ban)。這(zhe)種(zhong)(zhong)鋼(gang)(gang)板(ban)(ban)既(ji)具有防銹(xiu)性(xing)能(neng)，又(you)有良好(hao)的(de)涂裝性(xing)能(neng)。

彩(cai)(cai)鋼(gang)(gang)(gang)(gang)是(shi)指彩(cai)(cai)涂(tu)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)，彩(cai)(cai)涂(tu)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)是(shi)一(yi)(yi)種帶有(you)有(you)機涂(tu)層的(de)(de)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)，傳統的(de)(de)涂(tu)層分好幾類，氟碳涂(tu)層的(de)(de)，幾乎可以防腐20年。一(yi)(yi)般從鋼(gang)(gang)(gang)(gang)廠以卷筒的(de)(de)形式分銷到(dao)各地(di)。我們經常看到(dao)的(de)(de)彩(cai)(cai)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)是(shi)指加(jia)工(gong)好的(de)(de)板(ban)(ban)(ban)材(cai)，厚度在50~100mm左右(you)，它是(shi)由中間的(de)(de)填料和兩面的(de)(de)彩(cai)(cai)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)組成。其中，彩(cai)(cai)板(ban)(ban)(ban)厚度有(you)0.4mm、0.5mm、0.6mm等不(bu)同的(de)(de)厚度,中間層可以是(shi)聚胺脂、巖綿或泡沫塑料等。由于有(you)專(zhuan)用型材(cai)，所(suo)以用彩(cai)(cai)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)構筑的(de)(de)廠房建造速度很快（如非典時(shi)的(de)(de)小湯山醫院(yuan)），但(dan)強度低。
