熱(re)鍍(du)鋅(xin)生(sheng)產發展一直處于滯后狀態。20世(shi)紀50年代(dai)(dai)到60年代(dai)(dai)陸(lu)續建成了13條單(dan)張鋼(gang)板(ban)熔(rong)劑法熱(re)鍍(du)鋅(xin)機組(zu)，能力為(wei)10萬t/a，但因產量(liang)(liang)低(di)、成本高、質量(liang)(liang)差、污(wu)染環境、經濟(ji)效益(yi)差等缺陷已先后停(ting)、轉產。從(cong)20世(shi)紀70年代(dai)(dai)末，我(wo)國(guo)才(cai)開始建造大(da)型寬帶(dai)熱(re)鍍(du)鋅(xin)機組(zu)。熱(re)鍍(du)鋅(xin)帶(dai)鋼(gang)在我(wo)國(guo)市場一直是(shi)緊缺品種(zhong)。從(cong)20世(shi)紀90年代(dai)(dai)中期以來，每(mei)年都要從(cong)國(guo)外進(jin)口80-100萬t左右。隨著國(guo)內經濟(ji)的(de)發展，尤其是(shi)汽車、家電及建筑(zhu)業(ye)的(de)發展，對鍍(du)鋅(xin)帶(dai)鋼(gang)的(de)需(xu)求(qiu)量(liang)(liang)也(ye)大(da)大(da)增(zeng)加。

隨著鋼(gang)結(jie)構(gou)在(zai)建(jian)筑材料中的(de)(de)(de)興(xing)起，越來越多的(de)(de)(de)人選擇使用(yong)鋼(gang)結(jie)構(gou)樓(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)了(le)(le)(le)，鋼(gang)結(jie)構(gou)構(gou)件工廠產業化(hua)生產大(da)大(da)縮短(duan)了(le)(le)(le)工程工期(qi)，而樓(lou)(lou)(lou)(lou)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)施工方法卻(que)成(cheng)為(wei)影(ying)響(xiang)工期(qi)的(de)(de)(de)重(zhong)要因素(su)。采用(yong)那一(yi)代樓(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)對于樓(lou)(lou)(lou)(lou)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)耐火性能也有(you)區別。樓(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)厚(hou)(hou)(hou)(hou)度(du)(du)(du)(du)一(yi)般都是(shi)(shi)按(an)保險起見設計的(de)(de)(de)比較厚(hou)(hou)(hou)(hou)，正常情況下鋼(gang)梁之間的(de)(de)(de)跨(kua)度(du)(du)(du)(du)在(zai)2m以(yi)內(nei)樓(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)厚(hou)(hou)(hou)(hou)度(du)(du)(du)(du)在(zai)0.75-0.8mm就(jiu)可以(yi)了(le)(le)(le)，2-2.5m樓(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)厚(hou)(hou)(hou)(hou)度(du)(du)(du)(du)用(yong)0.8-1.0就(jiu)可以(yi)了(le)(le)(le)，跨(kua)度(du)(du)(du)(du)在(zai)3-4米樓(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)厚(hou)(hou)(hou)(hou)度(du)(du)(du)(du)用(yong)1.5mm，超(chao)過5m的(de)(de)(de)跨(kua)度(du)(du)(du)(du)是(shi)(shi)用(yong)臨時支(zhi)撐，因素(su)就(jiu)是(shi)(shi)混(hun)泥土(tu)澆筑的(de)(de)(de)高(gao)(gao)度(du)(du)(du)(du)，混(hun)泥土(tu)澆筑的(de)(de)(de)越高(gao)(gao)，樓(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)所需(xu)要的(de)(de)(de)厚(hou)(hou)(hou)(hou)度(du)(du)(du)(du)也就(jiu)越厚(hou)(hou)(hou)(hou)，還有(you)一(yi)個大(da)家容易忽略(lve)的(de)(de)(de)因素(su)就(jiu)是(shi)(shi)螺釘的(de)(de)(de)好壞也是(shi)(shi)決(jue)定(ding)樓(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)厚(hou)(hou)(hou)(hou)度(du)(du)(du)(du)的(de)(de)(de)，螺釘越好樓(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)承(cheng)(cheng)載力就(jiu)越強。

彩涂卷價格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。攀鋼彩涂卷價格按(an)生產(chan)及加工方法可分為(wei)以下(xia)幾類：熱浸(jin)(jin)鍍(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板。將薄鋼(gang)(gang)(gang)板浸(jin)(jin)入熔 微商(shang)貨源解的鋅(xin)(xin)槽中，使(shi)其(qi)表面(mian)粘附(fu)一層(ceng)鋅(xin)(xin)的薄鋼(gang)(gang)(gang)板。目前主要采(cai)用連續鍍(du)(du)鋅(xin)(xin)工藝生產(chan)，即把成(cheng)(cheng)卷的鋼(gang)(gang)(gang)板連續浸(jin)(jin)在(zai)(zai)熔解有鋅(xin)(xin)的鍍(du)(du)槽中制成(cheng)(cheng)鍍(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板；合(he)金化鍍(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板。這種鋼(gang)(gang)(gang)板也(ye)是用熱浸(jin)(jin)法制造，但在(zai)(zai)出槽后，立即把它加熱到５００℃左右，使(shi)其(qi)生成(cheng)(cheng)鋅(xin)(xin)和鐵的合(he)金被膜。這種鍍(du)(du)鋅(xin)(xin)板具有良(liang)好的涂料的密著(zhu)性和焊(han)接性。
