鍍(du)鋅(xin)(xin)(xin)(xin)(xin)鋼板(ban)(ban)(ban)是(shi)為防止鋼板(ban)(ban)(ban)表(biao)面遭受(shou)腐蝕，延(yan)長其使(shi)用壽命，在(zai)鋼板(ban)(ban)(ban)表(biao)面涂以一層金(jin)屬(shu)鋅(xin)(xin)(xin)(xin)(xin)，這種(zhong)涂鋅(xin)(xin)(xin)(xin)(xin)的(de)(de)(de)(de)薄鋼板(ban)(ban)(ban)稱為鍍(du)鋅(xin)(xin)(xin)(xin)(xin)板(ban)(ban)(ban)。按生產及加(jia)工方法(fa)可分為以下(xia)幾(ji)類(lei)：熱(re)浸(jin)鍍(du)鋅(xin)(xin)(xin)(xin)(xin)鋼板(ban)(ban)(ban)。將薄鋼板(ban)(ban)(ban)浸(jin)入熔 微商貨源解的(de)(de)(de)(de)鋅(xin)(xin)(xin)(xin)(xin)槽中，使(shi)其表(biao)面粘附一層鋅(xin)(xin)(xin)(xin)(xin)的(de)(de)(de)(de)薄鋼板(ban)(ban)(ban)。目前主(zhu)要采用連(lian)續(xu)(xu)鍍(du)鋅(xin)(xin)(xin)(xin)(xin)工藝生產，即把成卷的(de)(de)(de)(de)鋼板(ban)(ban)(ban)連(lian)續(xu)(xu)浸(jin)在(zai)熔解有鋅(xin)(xin)(xin)(xin)(xin)的(de)(de)(de)(de)鍍(du)槽中制成鍍(du)鋅(xin)(xin)(xin)(xin)(xin)鋼板(ban)(ban)(ban)；合(he)金(jin)化鍍(du)鋅(xin)(xin)(xin)(xin)(xin)鋼板(ban)(ban)(ban)。這種(zhong)鋼板(ban)(ban)(ban)也是(shi)用熱(re)浸(jin)法(fa)制造，但在(zai)出(chu)槽后，立即把它加(jia)熱(re)到５００℃左右，使(shi)其生成鋅(xin)(xin)(xin)(xin)(xin)和鐵的(de)(de)(de)(de)合(he)金(jin)被膜。這種(zhong)鍍(du)鋅(xin)(xin)(xin)(xin)(xin)板(ban)(ban)(ban)具有良好的(de)(de)(de)(de)涂料的(de)(de)(de)(de)密著性(xing)和焊接性(xing)。

什邡攀華鍍鋅角鋼隨著鋼結構在建筑材料中的興起，越來越多的人選擇使用鋼結構樓承板了，鋼結構構件工廠產業化生產大大縮短了工程工期，而樓板的施工方法卻成為影響工期的重要因素。采用那一代樓承板對于樓板的耐火性能也有區別。鍍鋅角鋼價格樓(lou)(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)的(de)(de)厚度(du)一般(ban)都是(shi)(shi)按(an)保險起(qi)見設計(ji)的(de)(de)比較厚，正(zheng)常情況下(xia)鋼梁之間的(de)(de)跨(kua)度(du)在2m以內樓(lou)(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)厚度(du)在0.75-0.8mm就可(ke)以了，2-2.5m樓(lou)(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)厚度(du)用0.8-1.0就可(ke)以了，跨(kua)度(du)在3-4米樓(lou)(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)厚度(du)用1.5mm，超過5m的(de)(de)跨(kua)度(du)是(shi)(shi)用臨時支撐(cheng)，因素(su)就是(shi)(shi)混泥土澆筑(zhu)的(de)(de)高(gao)度(du)，混泥土澆筑(zhu)的(de)(de)越(yue)高(gao)，樓(lou)(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)所需要的(de)(de)厚度(du)也就越(yue)厚，還有一個大家容易忽(hu)略的(de)(de)因素(su)就是(shi)(shi)螺釘(ding)的(de)(de)好(hao)壞(huai)也是(shi)(shi)決定樓(lou)(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)厚度(du)的(de)(de)，螺釘(ding)越(yue)好(hao)樓(lou)(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)的(de)(de)承(cheng)(cheng)(cheng)(cheng)載(zai)力就越(yue)強。
