彩鋼(gang)是指彩涂(tu)(tu)鋼(gang)板(ban)，彩涂(tu)(tu)鋼(gang)板(ban)是一種帶(dai)有(you)有(you)機涂(tu)(tu)層(ceng)的(de)鋼(gang)板(ban)，傳統的(de)涂(tu)(tu)層(ceng)分好(hao)幾(ji)類，氟碳涂(tu)(tu)層(ceng)的(de)，幾(ji)乎可以(yi)防腐20年(nian)。一般從鋼(gang)廠以(yi)卷(juan)筒的(de)形式分銷到(dao)各地。我們經常看到(dao)的(de)彩鋼(gang)板(ban)是指加工(gong)好(hao)的(de)板(ban)材(cai)，厚度(du)在50~100mm左右，它是由中(zhong)間的(de)填料和兩面的(de)彩鋼(gang)板(ban)組(zu)成。其中(zhong)，彩板(ban)厚度(du)有(you)0.4mm、0.5mm、0.6mm等不同(tong)的(de)厚度(du),中(zhong)間層(ceng)可以(yi)是聚胺脂、巖綿(mian)或泡(pao)沫(mo)塑料等。由于有(you)專用型材(cai)，所以(yi)用彩鋼(gang)板(ban)構筑的(de)廠房建造速度(du)很(hen)快(kuai)（如非典時的(de)小湯山醫院），但強度(du)低(di)。

鍍(du)鋅方(fang)管(guan)(guan)(guan)是(shi)一種(zhong)具以(yi)熱軋(ya)或冷軋(ya)鍍(du)鋅帶鋼(gang)(gang)或鍍(du)鋅卷板為(wei)坯料(liao)(liao)經冷彎曲加(jia)工成型(xing)后再經高(gao)頻焊接(jie)制成的(de)(de)(de)(de)方(fang)形(xing)截(jie)面(mian)形(xing)狀尺寸的(de)(de)(de)(de)空(kong)心方(fang)形(xing)的(de)(de)(de)(de)截(jie)面(mian)型(xing)鋼(gang)(gang)鋼(gang)(gang)管(guan)(guan)(guan)；鍍(du)鋅卷或將事(shi)先做好的(de)(de)(de)(de)冷彎空(kong)心型(xing)鋼(gang)(gang)管(guan)(guan)(guan)再經熱浸(jin)鍍(du)鋅加(jia)工而成的(de)(de)(de)(de)鍍(du)鋅方(fang)矩管(guan)(guan)(guan)。鍍(du)鋅量(liang)是(shi)表(biao)示鍍(du)鋅板鋅層厚度的(de)(de)(de)(de)一個普遍(bian)采(cai)用(yong)的(de)(de)(de)(de)有(you)(you)效方(fang)法。鍍(du)鋅量(liang)的(de)(de)(de)(de)單位為(wei)g/m2。鍍(du)鋅層通過鈍化處(chu)理，可減少潮溫貯運條件下產生折銹(xiu)蝕(白銹(xiu)) 。但這(zhe)種(zhong)化學處(chu)理的(de)(de)(de)(de)防腐蝕性(xing)能(neng)是(shi)有(you)(you)限的(de)(de)(de)(de)，而且，妨礙大多數涂料(liao)(liao)的(de)(de)(de)(de)附(fu)著(zhu)性(xing)。這(zhe)種(zhong)處(chu)理一般不用(yong)在鋅鐵合金鍍(du)層，除光整表(biao)面(mian)外(wai)，作為(wei)常規，生產廠對其他類型(xing)的(de)(de)(de)(de)鍍(du)鋅層均進(jin)行鈍化處(chu)理。
