我國建(jian)筑業(ye)中，噪(zao)聲(sheng)污染問題久為人們所(suo)詬病。輕(qing)型樓承(cheng)板的(de)(de)應用(yong)使得土(tu)建(jian)建(jian)筑物局(ju)面被打(da)破，集(ji)環境破壞及污染少、材(cai)料回收和(he)利用(yong)率高、符(fu)合(he)(he)可持續發展要求等眾多(duo)優(you)點于(yu)一身的(de)(de)樓承(cheng)板建(jian)筑應運而生，逐步被人們所(suo)接受。輕(qing)型樓承(cheng)板是近(jin)十年來發展較(jiao)快的(de)(de)領域，在采(cai)用(yong)輕(qing)型樓承(cheng)板占非住宅(zhai)建(jian)筑投資的(de)(de)50%以上。這種結構工業(ye)化、商品化程度高，施(shi)工快，綜合(he)(he)效(xiao)益高，市場需求量很大(da)，已(yi)引起結構設(she)計(ji)人員認識。樓承(cheng)板的(de)(de)研究開發已(yi)在各地試點，是輕(qing)鋼發展的(de)(de)一個重要方(fang)向，目前已(yi)經有(you)多(duo)種的(de)(de)低層、多(duo)層和(he)高層的(de)(de)設(she)計(ji)方(fang)案和(he)實例。

彩涂卷批發熱鍍鋅板和電鍍鋅板在鍍鋅量上有很大的差別，就像山東彩涂卷）。熱鍍鋅的鍍鋅量不可能太小，一般較小為雙面50～60g／m2，較大可達600g／m2。江津彩涂卷電(dian)鍍(du)鋅(xin)板的(de)(de)(de)鍍(du)鋅(xin)層可(ke)以(yi)很薄，較(jiao)(jiao)小達15g／m2，但(dan)要求鍍(du)層較(jiao)(jiao)厚的(de)(de)(de)話則(ze)生(sheng)產線(xian)速度很慢，不適(shi)應現代化(hua)機組(zu)的(de)(de)(de)工藝特點，一(yi)般較(jiao)(jiao)大為lO0g／m2左右。正因為如此，電(dian)鍍(du)鋅(xin)板的(de)(de)(de)生(sheng)產受到很大的(de)(de)(de)限制。工一(yi)般電(dian)鍍(du)鋅(xin)比較(jiao)(jiao)多，適(shi)用(yong)于(yu)小部件；熱鍍(du)鋅(xin)一(yi)般用(yong)于(yu)電(dian)力(li)設備和(he)構件，適(shi)用(yong)于(yu)大的(de)(de)(de)部件和(he)設備。當然(ran)他們的(de)(de)(de)價格也相(xiang)對便宜一(yi)些。建設部已正式下文，淘汰(tai)技術落(luo)后的(de)(de)(de)冷(leng)鍍(du)鋅(xin)管(guan)，不準用(yong)冷(leng)鍍(du)鋅(xin)管(guan)作水、煤氣管(guan)。

彩(cai)鋼(gang)(gang)(gang)是指彩(cai)涂(tu)(tu)鋼(gang)(gang)(gang)板，彩(cai)涂(tu)(tu)鋼(gang)(gang)(gang)板是一(yi)種(zhong)帶有有機涂(tu)(tu)層的(de)(de)(de)鋼(gang)(gang)(gang)板，傳統的(de)(de)(de)涂(tu)(tu)層分好(hao)(hao)幾類，氟碳涂(tu)(tu)層的(de)(de)(de)，幾乎可以(yi)防(fang)腐20年。一(yi)般從鋼(gang)(gang)(gang)廠(chang)以(yi)卷筒的(de)(de)(de)形(xing)式分銷到各地(di)。我們經常(chang)看到的(de)(de)(de)彩(cai)鋼(gang)(gang)(gang)板是指加工好(hao)(hao)的(de)(de)(de)板材，厚(hou)度在50~100mm左右，它是由中(zhong)間的(de)(de)(de)填(tian)料和兩面(mian)的(de)(de)(de)彩(cai)鋼(gang)(gang)(gang)板組成(cheng)。其中(zhong)，彩(cai)板厚(hou)度有0.4mm、0.5mm、0.6mm等不同的(de)(de)(de)厚(hou)度,中(zhong)間層可以(yi)是聚胺脂(zhi)、巖綿或(huo)泡沫塑料等。由于有專用型材，所(suo)以(yi)用彩(cai)鋼(gang)(gang)(gang)板構筑的(de)(de)(de)廠(chang)房建造(zao)速度很快（如(ru)非典時的(de)(de)(de)小湯山醫院），但強度低。
