渝中攀華鍍鋅角鋼要看整個樓板的厚度來考慮挑選是用75波高系列的仍是51波高系列的，沉默有40系列，46系列，60系列，65波高系列。鍍鋅角鋼批發一(yi)般(ban)來說(shuo)波(bo)(bo)(bo)(bo)高越低，承(cheng)載(zai)力(li)就越低，然(ran)后就是(shi)波(bo)(bo)(bo)(bo)峰距(ju)離越大，承(cheng)載(zai)力(li)就越小，假如整(zheng)個樓(lou)板厚度(du)在(zai)10公(gong)(gong)(gong)分(fen)以內(nei)，好(hao)(hao)選用(yong)選用(yong)波(bo)(bo)(bo)(bo)高40系列，整(zheng)個樓(lou)板厚度(du)在(zai)10-13公(gong)(gong)(gong)分(fen)以內(nei)，好(hao)(hao)選用(yong)50波(bo)(bo)(bo)(bo)高系列，在(zai)13公(gong)(gong)(gong)分(fen)以上，好(hao)(hao)選用(yong)75系列。有些人會問，為什么呀?其實《我(wo)國鋼(gang)筋混凝(ning)土修建規范(fan)》里有個要求，鋼(gang)筋上面(mian)的(de)(de)(de)混泥(ni)土保護層(ceng)不能低于2.5cm，就是(shi)說(shuo)樓(lou)承(cheng)板自身的(de)(de)(de)波(bo)(bo)(bo)(bo)高+鋼(gang)筋網的(de)(de)(de)厚度(du)(一(yi)般(ban)2cm)+2.5cm的(de)(de)(de)保護層(ceng)≤樓(lou)板的(de)(de)(de)厚度(du)。

彩(cai)鋼(gang)是指(zhi)彩(cai)涂(tu)鋼(gang)板(ban)(ban)，彩(cai)涂(tu)鋼(gang)板(ban)(ban)是一種帶有(you)有(you)機涂(tu)層的鋼(gang)板(ban)(ban)，傳統的涂(tu)層分(fen)好(hao)幾類，氟碳涂(tu)層的，幾乎可以(yi)防腐(fu)20年。一般從鋼(gang)廠(chang)以(yi)卷筒的形式(shi)分(fen)銷到各地。我(wo)們經常看到的彩(cai)鋼(gang)板(ban)(ban)是指(zhi)加(jia)工好(hao)的板(ban)(ban)材(cai)，厚度(du)在50~100mm左右，它是由(you)中間(jian)的填料和兩面的彩(cai)鋼(gang)板(ban)(ban)組成。其中，彩(cai)板(ban)(ban)厚度(du)有(you)0.4mm、0.5mm、0.6mm等(deng)不同的厚度(du),中間(jian)層可以(yi)是聚胺脂、巖綿或泡沫塑料等(deng)。由(you)于有(you)專用(yong)型材(cai)，所以(yi)用(yong)彩(cai)鋼(gang)板(ban)(ban)構筑的廠(chang)房(fang)建造速度(du)很快(kuai)（如非典時(shi)的小湯山醫院），但強度(du)低。
