鍍鋅帶鋼批發鍍鋅鋼板按用途又可分為一般用、屋頂用、建筑外側板用、結構用、瓦壟板用、拉伸用和深沖用等鍍鋅鋼板。江北鍍鋅帶鋼對(dui)于一般防(fang)保護用鍍(du)(du)層(ceng)，可以采(cai)用堿性鋅(xin)(xin)(xin)酸鹽鍍(du)(du)鋅(xin)(xin)(xin)彩色鈍化工藝(yi)(yi)。有時(shi)為了產品的(de)(de)(de)配色需要，也可以采(cai)用藍白色鈍化工藝(yi)(yi)，比(bi)如軍綠色鈍化、黑色鈍化等(deng)。為提高(gao)鋼(gang)(gang)(gang)管的(de)(de)(de)耐(nai)腐蝕(shi)性能，對(dui)一般鋼(gang)(gang)(gang)管進行鍍(du)(du)鋅(xin)(xin)(xin)。鍍(du)(du)鋅(xin)(xin)(xin)卷分熱(re)鍍(du)(du)鋅(xin)(xin)(xin)和電鍍(du)(du)鋅(xin)(xin)(xin)兩種，熱(re)鍍(du)(du)鋅(xin)(xin)(xin)鍍(du)(du)鋅(xin)(xin)(xin)層(ceng)厚(hou)，電鍍(du)(du)鋅(xin)(xin)(xin)成(cheng)(cheng)本低，表(biao)面不是很(hen)光(guang)滑。吹氧焊管：用作煉鋼(gang)(gang)(gang)吹氧用管，一般用小口徑的(de)(de)(de)焊接鋼(gang)(gang)(gang)管，規格由3/8-2寸八種。用08、10、15、20或者195-Q235的(de)(de)(de)鋼(gang)(gang)(gang)帶(dai)制(zhi)作成(cheng)(cheng)的(de)(de)(de)，為了防(fang)腐蝕(shi)，有得(de)進行滲鋁處理。鍍(du)(du)鋅(xin)(xin)(xin)其防(fang)護作用更強(qiang)(qiang)，抗腐蝕(shi)能力強(qiang)(qiang)。整個結(jie)構(gou)由鋅(xin)(xin)(xin)，形(xing)成(cheng)(cheng)致密的(de)(de)(de)四元結(jie)晶體，此結(jie)晶體在鋼(gang)(gang)(gang)板上(shang)形(xing)成(cheng)(cheng)一層(ceng)屏(ping)障， 因而有效的(de)(de)(de)防(fang)止腐蝕(shi)因子穿透。 耐(nai)腐蝕(shi)性來自鋅(xin)(xin)(xin)的(de)(de)(de)障礙層(ceng)保護功能強(qiang)(qiang)。

熱鍍(du)鋅(xin)(xin)生產發(fa)展(zhan)一直處于滯后狀態。20世紀(ji)50年(nian)代到60年(nian)代陸續建成了13條單張鋼板(ban)熔劑(ji)法熱鍍(du)鋅(xin)(xin)機(ji)(ji)組，能力為(wei)10萬(wan)t/a，但因(yin)產量低、成本高、質量差(cha)、污染環境(jing)、經濟(ji)效益差(cha)等缺陷(xian)已先后停(ting)、轉產。從(cong)20世紀(ji)70年(nian)代末，我國才開(kai)始建造大(da)型寬帶熱鍍(du)鋅(xin)(xin)機(ji)(ji)組。熱鍍(du)鋅(xin)(xin)帶鋼在(zai)我國市場一直是緊(jin)缺品種(zhong)。從(cong)20世紀(ji)90年(nian)代中期以(yi)來，每年(nian)都要(yao)從(cong)國外進口80-100萬(wan)t左右。隨著國內經濟(ji)的發(fa)展(zhan)，尤其是汽(qi)車、家(jia)電(dian)及建筑業的發(fa)展(zhan)，對鍍(du)鋅(xin)(xin)帶鋼的需求(qiu)量也大(da)大(da)增加。

實現(xian)了機械化生(sheng)產(chan)(chan)(chan)(chan)，有利(li)于鋼(gang)筋排列間距均勻(yun)、混凝土保(bao)護層(ceng)厚度一致，提高了樓(lou)板的(de)施工(gong)(gong)(gong)質量。裝(zhuang)配式鋼(gang)筋桁架樓(lou)承板可顯著減少現(xian)場鋼(gang)筋綁(bang)扎工(gong)(gong)(gong)程量，加快施工(gong)(gong)(gong)進度，增(zeng)加施工(gong)(gong)(gong)保(bao)證，實現(xian)文明施工(gong)(gong)(gong)。裝(zhuang)配式模板和(he)連接件(jian)拆裝(zhuang)方便，可多次重復(fu)利(li)用(yong)，節(jie)約鋼(gang)材，符(fu)合國(guo)家(jia)節(jie)能環保(bao)的(de)要求。鋼(gang)構(gou)自主研發的(de)產(chan)(chan)(chan)(chan)品(pin)配套自動(dong)化生(sheng)產(chan)(chan)(chan)(chan)設備，大(da)大(da)提高了勞動(dong)生(sheng)產(chan)(chan)(chan)(chan)率，有效降低了產(chan)(chan)(chan)(chan)品(pin)成本，并(bing)編(bian)制了產(chan)(chan)(chan)(chan)品(pin)生(sheng)產(chan)(chan)(chan)(chan)企業標(biao)準、設計手(shou)冊和(he)節(jie)點(dian)構(gou)造圖集以(yi)(yi)及施工(gong)(gong)(gong)手(shou)冊。并(bing)經過多項(xiang)工(gong)(gong)(gong)程應用(yong)，各項(xiang)性能可以(yi)(yi)滿足現(xian)澆鋼(gang)筋混凝土樓(lou)板承載力和(he)變形的(de)要求。
