璧山攀華鍍鋅卷樓承板鍍鋅首要起到防腐的效果，按標準組合樓板與非組合樓板壓型鋼板應選用熱鍍鋅，不該選用電鍍鋅鋼板，其雙面鍍鋅層總含量要滿足在使用期間不致銹損的要求。當作為非組合樓承板時，鍍鋅層含量可選用較低值;當為組合樓承板時，鍍鋅層含量不該小于150g/m2。當為組合樓板且使用環境條件較為惡劣時，鍍鋅層含量應選用上限值或更高值。更高的鍍鋅要求，如雙面鍍鋅量為300g/m2、350g/m2或鍍鋁鋅(5%鋁)275g/m2、300g/m2等，較高的鍍層量使組合樓板有更長耐久性，同等量的鍍鋁鋅的防銹蝕才能大約兩倍于一般熱鍍鋅。鍍鋅卷價格鍍(du)鋅(xin)量也不是越厚越好，當(dang)鍍(du)鋅(xin)量較厚時(shi)，抗(kang)剪連接件(jian)栓(shuan)釘(ding)的焊接質量就很難保證，焊接時(shi)，宜(yi)選(xuan)用局(ju)部除鋅(xin)處(chu)理措施。

鍍鋅(xin)(xin)板(ban)選(xuan)擇要(yao)注(zhu)(zhu)(zhu)重(zhong)(zhong)(zhong)(zhong)的(de)(de)(de)(de)幾(ji)個要(yao)點，工業(ye)(ye)企業(ye)(ye)的(de)(de)(de)(de)客戶選(xuan)擇專用(yong)工業(ye)(ye)原料，要(yao)注(zhu)(zhu)(zhu)重(zhong)(zhong)(zhong)(zhong)從(cong)(cong)四個標準。一(yi)是要(yao)注(zhu)(zhu)(zhu)重(zhong)(zhong)(zhong)(zhong)品(pin)牌來(lai)進行選(xuan)擇，因(yin)為鍍鋅(xin)(xin)技(ji)術(shu)的(de)(de)(de)(de)要(yao)求(qiu)嚴(yan)格，所以有的(de)(de)(de)(de)基礎，當然(ran)產(chan)品(pin)質(zhi)量(liang)(liang)與(yu)技(ji)術(shu)標準都會更可(ke)靠(kao)，都會有好的(de)(de)(de)(de)專業(ye)(ye)標準。二(er)是要(yao)注(zhu)(zhu)(zhu)重(zhong)(zhong)(zhong)(zhong)產(chan)品(pin)本(ben)身(shen)的(de)(de)(de)(de)鍍層質(zhi)量(liang)(liang)，鍍層一(yi)要(yao)靠(kao)技(ji)術(shu)，二(er)要(yao)靠(kao)純度，所以從(cong)(cong)產(chan)品(pin)表面來(lai)看(kan)質(zhi)量(liang)(liang)，這是基本(ben)也是重(zhong)(zhong)(zhong)(zhong)要(yao)的(de)(de)(de)(de)一(yi)個標準。三是要(yao)看(kan)基礎材(cai)料。鍍鋅(xin)(xin)板(ban)基礎金屬(shu)材(cai)料的(de)(de)(de)(de)質(zhi)量(liang)(liang)，與(yu)成品(pin)鍍鋅(xin)(xin)板(ban)的(de)(de)(de)(de)質(zhi)量(liang)(liang)與(yu)耐用(yong)性密切相關，所以在(zai)進行產(chan)品(pin)選(xuan)擇的(de)(de)(de)(de)時候，需要(yao)注(zhu)(zhu)(zhu)重(zhong)(zhong)(zhong)(zhong)這個細節，而(er)材(cai)料的(de)(de)(de)(de)提供(gong)，就是對(dui)于工業(ye)(ye)生產(chan)來(lai)說，有基礎條件。四是要(yao)注(zhu)(zhu)(zhu)重(zhong)(zhong)(zhong)(zhong)價格對(dui)比，不(bu)是好的(de)(de)(de)(de)就是貴的(de)(de)(de)(de)，但是如果廉價的(de)(de)(de)(de)把產(chan)品(pin)，那(nei)是不(bu)可(ke)信的(de)(de)(de)(de)。

首先，在鋼結構樓(lou)層板(ban)(ban)(ban)中(zhong)要達到耐火(huo)(huo)1.5小時(shi)，總的來說(shuo)可以選擇開(kai)(kai)口(kou)(kou)板(ban)(ban)(ban)、縮口(kou)(kou)板(ban)(ban)(ban)、閉口(kou)(kou)板(ban)(ban)(ban)三大類。規范上混凝土要高于(yu)開(kai)(kai)口(kou)(kou)板(ban)(ban)(ban)肋頂之上80mm，并且(qie)板(ban)(ban)(ban)底(di)需(xu)配(pei)置板(ban)(ban)(ban)底(di)受力(li)筋(jin)。還(huan)有一種(zhong)就是(shi)(shi)再開(kai)(kai)口(kou)(kou)板(ban)(ban)(ban)底(di)部刷防(fang)火(huo)(huo)涂(tu)料，涂(tu)料厚(hou)度大于(yu)等于(yu)15,這樣的話，只(zhi)要達到構造要求(qiu)高于(yu)肋頂5公分就可以了。而縮口(kou)(kou)板(ban)(ban)(ban)和閉口(kou)(kou)板(ban)(ban)(ban)，只(zhi)需(xu)要總的樓(lou)板(ban)(ban)(ban)厚(hou)度大于(yu)等于(yu)110即(ji)可，但是(shi)(shi)縮口(kou)(kou)板(ban)(ban)(ban)雖然在防(fang)火(huo)(huo)方(fang)面比開(kai)(kai)口(kou)(kou)板(ban)(ban)(ban)要好。但是(shi)(shi)底(di)部還(huan)是(shi)(shi)需(xu)要加板(ban)(ban)(ban)底(di)受力(li)筋(jin)，而閉口(kou)(kou)板(ban)(ban)(ban)則(ze)不需(xu)要。
