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)般來說波(bo)(bo)(bo)高越(yue)(yue)低，承載(zai)力就(jiu)越(yue)(yue)低，然后就(jiu)是(shi)波(bo)(bo)(bo)峰距(ju)離越(yue)(yue)大，承載(zai)力就(jiu)越(yue)(yue)小，假如整個樓板(ban)厚(hou)(hou)度在10公(gong)分(fen)以內(nei)，好(hao)選用選用波(bo)(bo)(bo)高40系列，整個樓板(ban)厚(hou)(hou)度在10-13公(gong)分(fen)以內(nei)，好(hao)選用50波(bo)(bo)(bo)高系列，在13公(gong)分(fen)以上，好(hao)選用75系列。有(you)些人會(hui)問，為什么呀?其實《我(wo)國鋼(gang)筋混凝(ning)土(tu)修(xiu)建(jian)規范》里(li)有(you)個要求(qiu)，鋼(gang)筋上面的(de)混泥(ni)土(tu)保護(hu)層不能低于(yu)2.5cm，就(jiu)是(shi)說樓承板(ban)自身的(de)波(bo)(bo)(bo)高+鋼(gang)筋網的(de)厚(hou)(hou)度(一(yi)般2cm)+2.5cm的(de)保護(hu)層≤樓板(ban)的(de)厚(hou)(hou)度。

彩(cai)鋼(gang)是(shi)指(zhi)彩(cai)涂鋼(gang)板(ban)(ban)(ban)，彩(cai)涂鋼(gang)板(ban)(ban)(ban)是(shi)一種帶有(you)(you)有(you)(you)機涂層(ceng)(ceng)的(de)鋼(gang)板(ban)(ban)(ban)，傳統的(de)涂層(ceng)(ceng)分好幾(ji)類，氟碳涂層(ceng)(ceng)的(de)，幾(ji)乎可(ke)以防腐20年。一般從鋼(gang)廠以卷筒的(de)形式分銷(xiao)到各地。我們經常看到的(de)彩(cai)鋼(gang)板(ban)(ban)(ban)是(shi)指(zhi)加工好的(de)板(ban)(ban)(ban)材，厚(hou)度(du)在50~100mm左右，它是(shi)由中間(jian)的(de)填料(liao)(liao)和兩面(mian)的(de)彩(cai)鋼(gang)板(ban)(ban)(ban)組成。其中，彩(cai)板(ban)(ban)(ban)厚(hou)度(du)有(you)(you)0.4mm、0.5mm、0.6mm等(deng)(deng)不同的(de)厚(hou)度(du),中間(jian)層(ceng)(ceng)可(ke)以是(shi)聚胺脂(zhi)、巖綿或泡沫塑料(liao)(liao)等(deng)(deng)。由于有(you)(you)專用(yong)型材，所(suo)以用(yong)彩(cai)鋼(gang)板(ban)(ban)(ban)構筑的(de)廠房(fang)建造速(su)度(du)很快（如(ru)非典時(shi)的(de)小湯山醫(yi)院），但強度(du)低。
