鍍(du)(du)(du)鋅方管(guan)(guan)是(shi)一(yi)種具以(yi)熱(re)軋(ya)或(huo)冷軋(ya)鍍(du)(du)(du)鋅帶鋼或(huo)鍍(du)(du)(du)鋅卷板(ban)(ban)(ban)為坯料經(jing)冷彎(wan)(wan)曲加(jia)工成(cheng)型后再經(jing)高頻(pin)焊接制成(cheng)的(de)方形截面形狀尺寸的(de)空心(xin)(xin)方形的(de)截面型鋼鋼管(guan)(guan);或(huo)將(jiang)事先做(zuo)好的(de)冷彎(wan)(wan)空心(xin)(xin)型鋼管(guan)(guan)再經(jing)熱(re)浸鍍(du)(du)(du)鋅加(jia)工而成(cheng)的(de)鍍(du)(du)(du)鋅方矩管(guan)(guan)。鍍(du)(du)(du)鋅卷廠產量隨著(zhu)國民生活水平不斷提高和城市化建設的(de)不斷推進，從(cong)現在(zai)的(de)1.6億(yi)噸每(mei)年，增加(jia)到3億(yi)噸甚至更多也不是(shi)什么很遙(yao)遠的(de)夢想(xiang)。作(zuo)為煉(lian)鋼原(yuan)料的(de)鐵礦(kuang)石(shi)與廢鋼，前者是(shi)不可的(de)資源，后者是(shi)可以(yi)循環利用(yong)(yong)的(de)資源。無論從(cong)環保(bao)角度還是(shi)從(cong)鋼企的(de)運作(zuo)成(cheng)本(ben)上看(kan)，廢鋼都(dou)有著(zhu)礦(kuang)石(shi)所無法比(bi)擬的(de)優勢(shi)。發展高強度熱(re)鍍(du)(du)(du)鋅鋼板(ban)(ban)(ban)。隨著(zhu)汽(qi)車工業逐漸向、節能(neng)方向發展，對汽(qi)車用(yong)(yong)鍍(du)(du)(du)鋅鋼板(ban)(ban)(ban)性(xing)能(neng)要求也進一(yi)步提高。為了汽(qi)車板(ban)(ban)(ban)的(de)耐腐蝕(shi)性(xing)，將(jiang)擴(kuo)大熱(re)鍍(du)(du)(du)鋅鋼板(ban)(ban)(ban)的(de)使用(yong)(yong)率。

熱鍍鋅鋼管價格彩鋼是指彩涂鋼板，彩涂鋼板是一種帶有有機涂層的鋼板，傳統的涂層分好幾類，氟碳涂層的，幾乎可以防腐20年。一般從鋼廠以卷筒的形式分銷到各地。我們經常看到的彩鋼板是指加工好的板材，厚度在50~100mm左右，它是由中間的填料和兩面的彩鋼板組成。其中，彩板厚度有0.4mm、0.5mm、0.6mm等不同的厚度,中間層可以是聚胺脂、巖綿或泡沫塑料等。蘭州酒鋼熱鍍鋅鋼管由于有專用(yong)型材(cai)，所以(yi)用(yong)彩(cai)鋼板構筑的(de)(de)廠房建造(zao)速度很快（如非典時的(de)(de)小湯山醫院），但強度低(di)。
