熱(re)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)板和電(dian)(dian)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)板在(zai)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)量上有(you)很(hen)大(da)的(de)差別，就(jiu)像山(shan)東彩涂(tu)卷）。熱(re)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)的(de)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)量不(bu)可能(neng)太小，一般(ban)較(jiao)小為雙面50～60g／m2，較(jiao)大(da)可達600g／m2。電(dian)(dian)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)板的(de)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)層可以很(hen)薄，較(jiao)小達15g／m2，但要求鍍(du)(du)(du)(du)層較(jiao)厚的(de)話則生產(chan)(chan)線速度很(hen)慢，不(bu)適應現代化機(ji)組(zu)的(de)工藝特點，一般(ban)較(jiao)大(da)為lO0g／m2左右。正(zheng)因(yin)為如此(ci)，電(dian)(dian)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)板的(de)生產(chan)(chan)受到很(hen)大(da)的(de)限制。工一般(ban)電(dian)(dian)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)比較(jiao)多(duo)，適用于小部件；熱(re)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)一般(ban)用于電(dian)(dian)力設備(bei)和構件，適用于大(da)的(de)部件和設備(bei)。當然(ran)他們的(de)價格也相對(dui)便宜一些。建設部已正(zheng)式下文，淘汰(tai)技術落(luo)后的(de)冷(leng)(leng)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)管(guan)，不(bu)準用冷(leng)(leng)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)管(guan)作水(shui)、煤(mei)氣管(guan)。
