鍍鋅板批發鍍鋅鋼板為基板的彩涂鋼板，除有鋅保護外，鋅層上的有機涂層起了覆蓋隔離作用，可防止鋼板生銹，使用壽命比鍍鋅鋼板更長，據介紹涂層鋼板的使用壽命比鍍鋅鋼板長50%。西昌鍍鋅板在(zai)(zai)連(lian)續機組上以冷(leng)軋帶(dai)鋼(gang)(gang)(gang)(gang)，鍍(du)鋅(xin)帶(dai)鋼(gang)(gang)(gang)(gang)（電鍍(du)鋅(xin)和熱鍍(du)鋅(xin)）為基(ji)板(ban)(ban)，經(jing)過表面預處(chu)理（脫脂和化學處(chu)理），用輥涂(tu)(tu)(tu)的方法，涂(tu)(tu)(tu)上一層(ceng)(ceng)(ceng)或多層(ceng)(ceng)(ceng)液態涂(tu)(tu)(tu)料，經(jing)過烘烤和冷(leng)卻所(suo)得的板(ban)(ban)材即為涂(tu)(tu)(tu)層(ceng)(ceng)(ceng)鋼(gang)(gang)(gang)(gang)板(ban)(ban)。由于涂(tu)(tu)(tu)層(ceng)(ceng)(ceng)可以有各種不同的顏色，習慣上把涂(tu)(tu)(tu)層(ceng)(ceng)(ceng)鋼(gang)(gang)(gang)(gang)板(ban)(ban)叫(jiao)做(zuo)彩色涂(tu)(tu)(tu)層(ceng)(ceng)(ceng)鋼(gang)(gang)(gang)(gang)板(ban)(ban)。又由于涂(tu)(tu)(tu)層(ceng)(ceng)(ceng)是在(zai)(zai)鋼(gang)(gang)(gang)(gang)板(ban)(ban)成型加工之前進行(xing)的，在(zai)(zai)國外(wai)這叫(jiao)做(zuo)預涂(tu)(tu)(tu)層(ceng)(ceng)(ceng)鋼(gang)(gang)(gang)(gang)板(ban)(ban)。

首先，在鋼(gang)結構(gou)樓層板(ban)(ban)(ban)(ban)(ban)中要(yao)達到(dao)耐火1.5小(xiao)時(shi)，總的(de)來說可(ke)以選(xuan)擇開口板(ban)(ban)(ban)(ban)(ban)、縮(suo)口板(ban)(ban)(ban)(ban)(ban)、閉口板(ban)(ban)(ban)(ban)(ban)三(san)大(da)類。規范上(shang)混凝土要(yao)高(gao)(gao)于(yu)(yu)(yu)開口板(ban)(ban)(ban)(ban)(ban)肋頂(ding)之上(shang)80mm，并且板(ban)(ban)(ban)(ban)(ban)底(di)(di)需配置(zhi)板(ban)(ban)(ban)(ban)(ban)底(di)(di)受力筋(jin)。還有一種就是(shi)(shi)再開口板(ban)(ban)(ban)(ban)(ban)底(di)(di)部刷防火涂料，涂料厚度大(da)于(yu)(yu)(yu)等(deng)(deng)于(yu)(yu)(yu)15,這(zhe)樣的(de)話，只(zhi)要(yao)達到(dao)構(gou)造要(yao)求高(gao)(gao)于(yu)(yu)(yu)肋頂(ding)5公(gong)分就可(ke)以了。而(er)縮(suo)口板(ban)(ban)(ban)(ban)(ban)和閉口板(ban)(ban)(ban)(ban)(ban)，只(zhi)需要(yao)總的(de)樓板(ban)(ban)(ban)(ban)(ban)厚度大(da)于(yu)(yu)(yu)等(deng)(deng)于(yu)(yu)(yu)110即可(ke)，但是(shi)(shi)縮(suo)口板(ban)(ban)(ban)(ban)(ban)雖然在防火方面比開口板(ban)(ban)(ban)(ban)(ban)要(yao)好。但是(shi)(shi)底(di)(di)部還是(shi)(shi)需要(yao)加板(ban)(ban)(ban)(ban)(ban)底(di)(di)受力筋(jin)，而(er)閉口板(ban)(ban)(ban)(ban)(ban)則不需要(yao)。
