鍍(du)(du)(du)(du)鋅卷(juan)分熱鍍(du)(du)(du)(du)鋅和電鍍(du)(du)(du)(du)鋅兩種，熱鍍(du)(du)(du)(du)鋅鍍(du)(du)(du)(du)鋅層(ceng)厚，具有鍍(du)(du)(du)(du)層(ceng)均勻，附著力強(qiang)，使用壽命長(chang)等優點。電鍍(du)(du)(du)(du)鋅成本低，表面(mian)不是(shi)很(hen)光滑(hua)，其本身(shen)的耐(nai)腐蝕性(xing)比熱鍍(du)(du)(du)(du)鋅管(guan)相(xiang)差很(hen)多(duo)(duo)。提起鍍(du)(du)(du)(du)鋅管(guan)，可能(neng)沒(mei)接(jie)觸(chu)過建材的朋友并不了解。從1935年建立(li)一(yi)條連續涂(tu)(tu)層(ceng)鋼(gang)板線開始(shi)，彩(cai)涂(tu)(tu)板得到了廣泛應(ying)用，目前(qian)彩(cai)涂(tu)(tu)板的品種繁(fan)多(duo)(duo)，大約超過600種，彩(cai)涂(tu)(tu)板兼有機(ji)聚(ju)合物與鋼(gang)板兩者的優點，既有有機(ji)聚(ju)合物的良好著色性(xing)、成型性(xing)、耐(nai)蝕性(xing)、裝飾性(xing)、又有鋼(gang)板的高強(qiang)度和易加工性(xing)，能(neng)很(hen)容易地進行沖壓(ya)裁剪(jian)、彎(wan)曲、深(shen)沖等加工。

鍍鋅角鋼價格鍍鋅是一種經常采用的經濟而有效的防腐方法。鋅產量的一半左右均用于此種工藝。鍍鋅卷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，這種涂鋅的鋼板稱為鍍鋅卷。昆山鍍鋅角鋼鍍鋅卷(juan)(juan)(juan)主要用于(yu)建筑、家(jia)(jia)電、汽(qi)車(che)(che)、容器(qi)、交通及(ji)家(jia)(jia)業等領(ling)域。特別是鋼結構建筑、汽(qi)車(che)(che)制(zhi)造、鋼板倉制(zhi)造等行業。耐腐蝕強、表面質量好、得利于(yu)深加工、經濟實用等。有關產品標準都列(lie)明鍍鋅卷(juan)(juan)(juan)推薦的(de)標準厚(hou)度、長度和寬(kuan)度及(ji)其允許偏差。鍍鋅卷(juan)(juan)(juan)厚(hou)度偏差一般在(zai)0.05mm，長寬(kuan)偏差一般在(zai)5mm ，板材的(de)厚(hou)度一般在(zai)0.2-3.2之間(jian) 。

熱(re)(re)(re)鍍(du)鋅(xin)生產(chan)發(fa)展(zhan)一(yi)(yi)直處于(yu)滯(zhi)后(hou)狀態(tai)。20世(shi)紀(ji)50年(nian)(nian)代到60年(nian)(nian)代陸續建(jian)(jian)成了13條單張(zhang)鋼板熔(rong)劑法熱(re)(re)(re)鍍(du)鋅(xin)機組，能力(li)為(wei)10萬t/a，但因產(chan)量低(di)、成本高、質量差(cha)、污染環境(jing)、經濟效益差(cha)等缺陷已先(xian)后(hou)停、轉產(chan)。從(cong)20世(shi)紀(ji)70年(nian)(nian)代末，我國才(cai)開始建(jian)(jian)造大型寬帶(dai)熱(re)(re)(re)鍍(du)鋅(xin)機組。熱(re)(re)(re)鍍(du)鋅(xin)帶(dai)鋼在我國市場一(yi)(yi)直是緊缺品種。從(cong)20世(shi)紀(ji)90年(nian)(nian)代中期以來(lai)，每(mei)年(nian)(nian)都要從(cong)國外進口80-100萬t左右。隨著國內經濟的(de)發(fa)展(zhan)，尤其(qi)是汽車、家電及(ji)建(jian)(jian)筑業的(de)發(fa)展(zhan)，對鍍(du)鋅(xin)帶(dai)鋼的(de)需求量也大大增加。
