廣西攀鋼鍍鋅鋼板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。鍍鋅鋼板價格鍍(du)鋅(xin)量也不(bu)是越厚(hou)越好(hao)，當鍍(du)鋅(xin)量較厚(hou)時(shi)，抗剪連接(jie)件(jian)栓(shuan)釘的焊接(jie)質量就很難保證，焊接(jie)時(shi)，宜(yi)選用(yong)局部除鋅(xin)處理措施。
