鍍鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)為基板(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)彩(cai)涂(tu)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)，除有(you)鋅(xin)(xin)(xin)(xin)保護外，鋅(xin)(xin)(xin)(xin)層(ceng)(ceng)(ceng)(ceng)(ceng)上的(de)(de)(de)有(you)機涂(tu)層(ceng)(ceng)(ceng)(ceng)(ceng)起了覆蓋隔離作用，可防止鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)生銹，使用壽命比鍍鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)更(geng)長(chang)，據介紹(shao)涂(tu)層(ceng)(ceng)(ceng)(ceng)(ceng)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)使用壽命比鍍鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)長(chang)50%。在(zai)連續(xu)機組上以(yi)冷軋帶(dai)鋼(gang)(gang)，鍍鋅(xin)(xin)(xin)(xin)帶(dai)鋼(gang)(gang)（電鍍鋅(xin)(xin)(xin)(xin)和熱鍍鋅(xin)(xin)(xin)(xin)）為基板(ban)(ban)(ban)(ban)(ban)(ban)，經過表面預(yu)(yu)處(chu)理（脫脂和化學處(chu)理），用輥(gun)涂(tu)的(de)(de)(de)方法，涂(tu)上一層(ceng)(ceng)(ceng)(ceng)(ceng)或多層(ceng)(ceng)(ceng)(ceng)(ceng)液態涂(tu)料，經過烘烤和冷卻(que)所得(de)的(de)(de)(de)板(ban)(ban)(ban)(ban)(ban)(ban)材即為涂(tu)層(ceng)(ceng)(ceng)(ceng)(ceng)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)。由于涂(tu)層(ceng)(ceng)(ceng)(ceng)(ceng)可以(yi)有(you)各種不同的(de)(de)(de)顏色，習慣上把涂(tu)層(ceng)(ceng)(ceng)(ceng)(ceng)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)叫(jiao)做(zuo)彩(cai)色涂(tu)層(ceng)(ceng)(ceng)(ceng)(ceng)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)。又由于涂(tu)層(ceng)(ceng)(ceng)(ceng)(ceng)是在(zai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)成型加(jia)工之(zhi)前(qian)進行的(de)(de)(de)，在(zai)國(guo)外這叫(jiao)做(zuo)預(yu)(yu)涂(tu)層(ceng)(ceng)(ceng)(ceng)(ceng)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)。

重慶鍍鋅重慶樓承板由于在高層建筑和大跨度高聳結構方面的優越性，使其在非居住建筑領域得到了廣泛的應用。用環保鋼筋桁架樓承板建筑的房子比傳統房屋的重量要輕一倍，運用面積也進步百分之五左右，這個就是它一大優點自重輕強度高。鍍鋅價格依(yi)據(ju)不完整(zheng)的(de)(de)統計，我國在發作(zuo)(zuo)地震時(shi)鋼(gang)筋(jin)桁架樓承板建筑(zhu)的(de)(de)倒塌幾率簡(jian)直是零，所(suo)(suo)以它的(de)(de)抗(kang)震性(xing)能好也是它的(de)(de)優點之(zhi)一，由(you)于(yu)鋼(gang)筋(jin)桁架樓承板建筑(zhu)的(de)(de)一些構件、墻板等有(you)關(guan)的(de)(de)建材(cai)都是在工(gong)(gong)廠里完成的(de)(de)，所(suo)(suo)以就減少了現場施工(gong)(gong)的(de)(de)工(gong)(gong)作(zuo)(zuo)量(liang)，縮短了施工(gong)(gong)的(de)(de)工(gong)(gong)作(zuo)(zuo)時(shi)間，很契合產業化的(de)(de)請求，這個是它的(de)(de)優勢，第三(san)個就是它的(de)(de)可回收應(ying)用了，它能夠隨意的(de)(de)撤除和(he)建造，關(guan)于(yu)環(huan)境不形成污染，還節約了資源(yuan)。
