閬中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。鍍鋅卷價格鍍鋅(xin)量(liang)也(ye)不(bu)是越(yue)厚越(yue)好，當鍍鋅(xin)量(liang)較厚時，抗剪連接(jie)件栓釘的焊接(jie)質量(liang)就(jiu)很難保(bao)證，焊接(jie)時，宜選用局部除鋅(xin)處理措施(shi)。
