鍍(du)(du)(du)(du)(du)鋅(xin)鋼板按用(yong)(yong)(yong)途又可分(fen)為一般用(yong)(yong)(yong)、屋頂用(yong)(yong)(yong)、建筑外側板用(yong)(yong)(yong)、結(jie)構用(yong)(yong)(yong)、瓦壟板用(yong)(yong)(yong)、拉(la)伸用(yong)(yong)(yong)和深沖用(yong)(yong)(yong)等鍍(du)(du)(du)(du)(du)鋅(xin)鋼板。熱鍍(du)(du)(du)(du)(du)鋅(xin)板主要應用(yong)(yong)(yong)于建筑外用(yong)(yong)(yong)，建筑內用(yong)(yong)(yong)，民用(yong)(yong)(yong)，門窗，家具(ju)，機(ji)械，電(dian)子及家用(yong)(yong)(yong)電(dian)器等領(ling)域。也有機(ji)箱用(yong)(yong)(yong)這(zhe)個，不過熱鍍(du)(du)(du)(du)(du)鋅(xin)板不放輻射的(de)(de)(de)(de)。空調，冰(bing)箱，微波爐及其類似家電(dian)背面的(de)(de)(de)(de)那個板就是(shi)熱鍍(du)(du)(du)(du)(du)鋅(xin)板。鍍(du)(du)(du)(du)(du)鋅(xin)層通過鈍化(hua)(hua)處理，可減少潮溫貯運條(tiao)件下產生(sheng)(sheng)折(zhe)銹(xiu)蝕(白銹(xiu)) 。但(dan)這(zhe)種(zhong)化(hua)(hua)學處理的(de)(de)(de)(de)防腐蝕性(xing)能是(shi)有限的(de)(de)(de)(de)，而且，妨礙大多數涂料的(de)(de)(de)(de)附著性(xing)。這(zhe)種(zhong)處理一般不用(yong)(yong)(yong)在鋅(xin)鐵合金鍍(du)(du)(du)(du)(du)層，除光整表面外，作為常規，生(sheng)(sheng)產廠對其他類型(xing)的(de)(de)(de)(de)鍍(du)(du)(du)(du)(du)鋅(xin)層均進行鈍化(hua)(hua)處理。

鍍鋅鋼管批發熱鍍鋅卷板價格行業統計數據顯示，十一月國內粗鋼日均產量為兩百零九萬噸，環比下降3.3%，創出今年以來水平，但是當前減產受到季節性因素支撐，市場對數據有效性提出質疑。樂山鍍鋅鋼管鍍鋅(xin)卷(juan)工業(ye)品而言，近期(qi)陸(lu)續公(gong)布的(de)重要數據中性偏多。但值(zhi)(zhi)得注意的(de)是，同(tong)年十一(yi)月熱鍍鋅(xin)卷(juan)板價格工業(ye)增(zeng)加值(zhi)(zhi)和投資增(zeng)速放緩，進一(yi)步(bu)印證了國內(nei)總需(xu)求乏力(li)，工業(ye)復蘇(su)形勢不(bu)容樂觀。加上未(wei)來經濟(ji)結構調整等因素，工業(ye)品價格反彈高(gao)度將有限。傳統需(xu)求淡季(ji)效應(ying)還在(zai)持續不(bu)斷地(di)發酵，冬儲效果不(bu)佳。雖然數據顯(xian)示供應(ying)壓(ya)力(li)開始減輕，但是目(mu)前(qian)處于鋼(gang)鐵需(xu)求淡季(ji)，市場成(cheng)交萎(wei)縮，下游采購遲(chi)遲(chi)未(wei)能有效跟進，市場信心不(bu)足，鍍鋅(xin)鋼(gang)板貿易商(shang)囤貨現象也(ye)不(bu)明顯(xian)。

堆積(ji)樓(lou)(lou)承板(ban)(ban)的(de)地坪應(ying)(ying)基本平坦，鋼(gang)筋(jin)桁架樓(lou)(lou)承板(ban)(ban)堆積(ji)不宜過(guo)高，每堆不超越60張(zhang)。樓(lou)(lou)承板(ban)(ban)運至(zhi)現場，需(xu)妥善保護，不得有(you)(you)任何損(sun)壞和污染(ran)，特別不得感染(ran)油污。樓(lou)(lou)承板(ban)(ban)應(ying)(ying)根(gen)據排版圖預先(xian)切開、編號。起(qi)吊(diao)前，每捆(kun)要(yao)有(you)(you)兩條鋼(gang)絲繩，分(fen)別捆(kun)于兩頭(tou)四分(fen)之一鋼(gang)板(ban)(ban)長度(du)處(chu)，采用(yong)專用(yong)吊(diao)具吊(diao)起(qi)。應(ying)(ying)先(xian)行(xing)試吊(diao)，檢查重心(xin)是否(fou)穩定，鋼(gang)索是否(fou)會滑動，待牢(lao)靠，無慮時方可吊(diao)起(qi)。起(qi)吊(diao)時，應(ying)(ying)從(cong)下往上(shang)樓(lou)(lou)層(ceng)次序吊(diao)料為原則，避免(mian)因先(xian)行(xing)吊(diao)放(fang)上(shang)層(ceng)資(zi)料后，阻止下面樓(lou)(lou)層(ceng)的(de)吊(diao)放(fang)作業。整疊樓(lou)(lou)承板(ban)(ban)放(fang)梁(liang)面時，應(ying)(ying)考慮梁(liang)的(de)承載(zai)能(neng)力，避免(mian)因集(ji)中(zhong)載(zai)荷過(guo)大，造成梁(liang)的(de)變形。樓(lou)(lou)承板(ban)(ban)吊(diao)至(zhi)樓(lou)(lou)層(ceng)，暫時不鋪設時，應(ying)(ying)作牢(lao)靠固定，避免(mian)飛落(luo)和滑落(luo)傷人。

近期鋼價(jia)(jia)(jia)延續低迷，隨(sui)著(zhu)通國規(gui)模(mo)的酷暑和旱(han)季到來，熱鍍(du)(du)鋅(xin)卷板價(jia)(jia)(jia)格商(shang)場逐漸進入需要旺(wang)季，海(hai)內(nei)(nei)鋼鐵商(shang)場或將窄幅調(diao)整。在決策層兩手(shou)抓制度(du)措施落實狀況、貨(huo)銀本位度(du)定向寬松力度(du)加大的直觀層面利(li)好牽動下，商(shang)場信念逐漸趨穩，短期海(hai)內(nei)(nei)鋼價(jia)(jia)(jia)無望止跌企穩;另一(yi)上面，以后鋼價(jia)(jia)(jia)殺(sha)跌電能有余，而(er)上漲也(ye)仍然屏障(zhang)重重。熱鍍(du)(du)鋅(xin)卷板價(jia)(jia)(jia)格價(jia)(jia)(jia)錢或將長期在于低位運行(xing)場面。

熱鍍(du)(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)和電(dian)鍍(du)(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)在鍍(du)(du)(du)鋅(xin)(xin)(xin)量上有很(hen)大(da)(da)的差別，就像山東彩(cai)涂卷）。熱鍍(du)(du)(du)鋅(xin)(xin)(xin)的鍍(du)(du)(du)鋅(xin)(xin)(xin)量不(bu)可能(neng)太小(xiao)(xiao)，一(yi)般(ban)較小(xiao)(xiao)為雙面50～60g／m2，較大(da)(da)可達(da)600g／m2。電(dian)鍍(du)(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)的鍍(du)(du)(du)鋅(xin)(xin)(xin)層(ceng)可以很(hen)薄(bo)，較小(xiao)(xiao)達(da)15g／m2，但要求鍍(du)(du)(du)層(ceng)較厚的話則(ze)生產線速(su)度很(hen)慢，不(bu)適(shi)應現代化機組的工藝特(te)點(dian)，一(yi)般(ban)較大(da)(da)為lO0g／m2左右。正(zheng)因為如此，電(dian)鍍(du)(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)的生產受到很(hen)大(da)(da)的限制。工一(yi)般(ban)電(dian)鍍(du)(du)(du)鋅(xin)(xin)(xin)比(bi)較多，適(shi)用(yong)于小(xiao)(xiao)部(bu)件(jian)；熱鍍(du)(du)(du)鋅(xin)(xin)(xin)一(yi)般(ban)用(yong)于電(dian)力(li)設備和構件(jian)，適(shi)用(yong)于大(da)(da)的部(bu)件(jian)和設備。當然他們的價格也相(xiang)對便宜一(yi)些。建設部(bu)已正(zheng)式下文，淘汰(tai)技術落后(hou)的冷(leng)鍍(du)(du)(du)鋅(xin)(xin)(xin)管，不(bu)準用(yong)冷(leng)鍍(du)(du)(du)鋅(xin)(xin)(xin)管作水、煤氣管。
