鍍(du)(du)(du)鋅(xin)卷(juan)分熱鍍(du)(du)(du)鋅(xin)和(he)電鍍(du)(du)(du)鋅(xin)兩種，熱鍍(du)(du)(du)鋅(xin)鍍(du)(du)(du)鋅(xin)層厚，具有鍍(du)(du)(du)層均勻，附著力強，使用(yong)壽命長(chang)等優點。電鍍(du)(du)(du)鋅(xin)成本(ben)(ben)低，表(biao)面不是很(hen)光滑，其本(ben)(ben)身的(de)(de)(de)耐腐蝕性比熱鍍(du)(du)(du)鋅(xin)管(guan)相差(cha)很(hen)多(duo)。提起(qi)鍍(du)(du)(du)鋅(xin)管(guan)，可能沒接觸過(guo)建(jian)材的(de)(de)(de)朋友并不了解。從1935年(nian)建(jian)立(li)一(yi)條連(lian)續涂層鋼板線開始(shi)，彩(cai)涂板得到了廣(guang)泛應用(yong)，目前彩(cai)涂板的(de)(de)(de)品種繁多(duo)，大約超過(guo)600種，彩(cai)涂板兼(jian)有機聚合物(wu)與鋼板兩者的(de)(de)(de)優點，既有有機聚合物(wu)的(de)(de)(de)良好著色性、成型性、耐蝕性、裝飾性、又有鋼板的(de)(de)(de)高強度和(he)易(yi)加工(gong)性，能很(hen)容易(yi)地(di)進行沖壓裁剪、彎曲、深沖等加工(gong)。

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。南寧鍍鋅角鋼鍍(du)鋅(xin)(xin)卷主(zhu)要(yao)用于(yu)建(jian)筑、家電、汽車(che)、容(rong)器、交(jiao)通(tong)及家業等領(ling)域。特(te)別是鋼(gang)結構建(jian)筑、汽車(che)制(zhi)造(zao)、鋼(gang)板倉制(zhi)造(zao)等行業。耐腐蝕強、表(biao)面質(zhi)量好、得利于(yu)深(shen)加工、經(jing)濟實用等。有關(guan)產品標(biao)準都列明鍍(du)鋅(xin)(xin)卷推(tui)薦的標(biao)準厚度(du)(du)、長(chang)度(du)(du)和寬度(du)(du)及其允許偏差(cha)。鍍(du)鋅(xin)(xin)卷厚度(du)(du)偏差(cha)一般在(zai)0.05mm，長(chang)寬偏差(cha)一般在(zai)5mm ，板材的厚度(du)(du)一般在(zai)0.2-3.2之(zhi)間(jian) 。
