鍍鋅(xin)鋼板(ban)(ban)(ban)(ban)按用(yong)(yong)(yong)途又可分為一(yi)般用(yong)(yong)(yong)、屋頂用(yong)(yong)(yong)、建(jian)(jian)筑外側板(ban)(ban)(ban)(ban)用(yong)(yong)(yong)、結(jie)構用(yong)(yong)(yong)、瓦壟板(ban)(ban)(ban)(ban)用(yong)(yong)(yong)、拉伸(shen)用(yong)(yong)(yong)和深沖用(yong)(yong)(yong)等(deng)鍍鋅(xin)鋼板(ban)(ban)(ban)(ban)。熱鍍鋅(xin)板(ban)(ban)(ban)(ban)主要應(ying)用(yong)(yong)(yong)于建(jian)(jian)筑外用(yong)(yong)(yong)，建(jian)(jian)筑內用(yong)(yong)(yong)，民用(yong)(yong)(yong)，門窗，家具，機(ji)械，電(dian)(dian)子及家用(yong)(yong)(yong)電(dian)(dian)器等(deng)領域。也有(you)機(ji)箱用(yong)(yong)(yong)這個，不(bu)過(guo)熱鍍鋅(xin)板(ban)(ban)(ban)(ban)不(bu)放(fang)輻射(she)的(de)(de)。空(kong)調，冰(bing)箱，微(wei)波爐及其(qi)類(lei)似家電(dian)(dian)背面的(de)(de)那個板(ban)(ban)(ban)(ban)就是熱鍍鋅(xin)板(ban)(ban)(ban)(ban)。鍍鋅(xin)層通過(guo)鈍化處(chu)(chu)理，可減少潮溫貯(zhu)運條件下產生折銹蝕(shi)(白銹) 。但這種化學(xue)處(chu)(chu)理的(de)(de)防腐(fu)蝕(shi)性能(neng)是有(you)限(xian)的(de)(de)，而且，妨礙大多數(shu)涂料(liao)的(de)(de)附(fu)著性。這種處(chu)(chu)理一(yi)般不(bu)用(yong)(yong)(yong)在鋅(xin)鐵合金鍍層，除光整(zheng)表面外，作為常規，生產廠對其(qi)他類(lei)型的(de)(de)鍍鋅(xin)層均進行鈍化處(chu)(chu)理。

樓(lou)(lou)承(cheng)板的(de)(de)使(shi)(shi)用是需要(yao)安裝的(de)(de)，那么如(ru)果要(yao)安裝就(jiu)要(yao)選(xuan)擇合適的(de)(de)小配件，焊后栓釘(ding)高(gao)度(du)大(da)于壓型鋼(gang)板波高(gao)30MM(留意挑(tiao)選(xuan)樓(lou)(lou)板的(de)(de)類型);栓釘(ding)頂面混(hun)凝土保護層不(bu)小于15MM(留意樓(lou)(lou)板總厚(hou)(hou)度(du))直徑不(bu)宜大(da)于19MM。樓(lou)(lou)承(cheng)板栓釘(ding)類型有ф8、ф10、ф13、ф16、ф19、ф22、ф25，栓釘(ding)一(yi)(yi)般(ban)(ban)在鋼(gang)結構修建中,遍及使(shi)(shi)用在柱腳(jiao)和樓(lou)(lou)板中,一(yi)(yi)般(ban)(ban)剛度(du)要(yao)求高(gao)的(de)(de)柱腳(jiao)都選(xuan)用鋼(gang)柱內伸至混(hun)凝土中，鋼(gang)柱埋入混(hun)凝土的(de)(de)部位四(si)周(zhou)均布栓釘(ding)。樓(lou)(lou)承(cheng)板輕鋼(gang)結構常用厚(hou)(hou)度(du)為0.8mm,1.0mm，1.2mm,荷載較大(da)的(de)(de)情況下會(hui)用到1.5mm。一(yi)(yi)般(ban)(ban)需要(yao)用栓釘(ding)與鋼(gang)梁銜接，板中配少量鋼(gang)筋，上面澆混(hun)凝土層，總厚(hou)(hou)度(du)約在100-200mm之間(jian)。

鍍鋅角鋼價格熱鍍鋅生產發展一直處于滯后狀態。20世紀50年代到60年代陸續建成了13條單張鋼板熔劑法熱鍍鋅機組，能力為10萬t/a，但因產量低、成本高、質量差、污染環境、經濟效益差等缺陷已先后停、轉產。從20世紀70年代末，我國才開始建造大型寬帶熱鍍鋅機組。銅仁鍍鋅角鋼熱(re)鍍鋅帶(dai)鋼(gang)在(zai)我(wo)國市場一直是緊缺品種(zhong)。從(cong)20世(shi)紀(ji)90年代(dai)中期(qi)以(yi)來(lai)，每年都要從(cong)國外進口80-100萬t左右。隨著國內(nei)經濟(ji)的發展，尤其是汽車、家電及建(jian)筑業的發展，對鍍鋅帶(dai)鋼(gang)的需求(qiu)量也大大增加(jia)。

近期(qi)鋼價(jia)延續(xu)低迷，隨著通國規模的酷暑和旱季(ji)到來，熱鍍鋅(xin)卷板價(jia)格商(shang)場(chang)逐漸進入需要(yao)旺季(ji)，海(hai)內鋼鐵商(shang)場(chang)或將窄幅調整。在決策(ce)層(ceng)(ceng)兩手抓制度措施落(luo)實狀況(kuang)、貨銀(yin)本位度定向寬松力度加大的直觀(guan)層(ceng)(ceng)面(mian)利好牽動下，商(shang)場(chang)信念逐漸趨穩，短期(qi)海(hai)內鋼價(jia)無望止跌企(qi)穩;另一上(shang)面(mian)，以后鋼價(jia)殺(sha)跌電能(neng)有余，而上(shang)漲也仍然屏障重(zhong)重(zhong)。熱鍍鋅(xin)卷板價(jia)格價(jia)錢或將長期(qi)在于低位運行場(chang)面(mian)。
