樓(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)適應主體鋼結構快速施工的(de)(de)要(yao)求(qiu)，能夠在(zai)(zai)短時間內提供(gong)堅(jian)定的(de)(de)作業平臺，并可采用多個樓(lou)(lou)(lou)層(ceng)鋪設(she)壓(ya)(ya)型鋼板(ban)(ban)(ban)(ban)，分層(ceng)澆筑混凝(ning)土板(ban)(ban)(ban)(ban)的(de)(de)流水施工。在(zai)(zai)使(shi)用階段樓(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)作為混凝(ning)土樓(lou)(lou)(lou)板(ban)(ban)(ban)(ban)的(de)(de)受拉鋼筋，也提高了樓(lou)(lou)(lou)板(ban)(ban)(ban)(ban)的(de)(de)剛度(du)，節省了鋼筋和混凝(ning)土的(de)(de)用量。樓(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)上(shang)面可以鋪設(she)保(bao)溫(wen)，隔(ge)音，隔(ge)熱，隔(ge)振等材(cai)料。樓(lou)(lou)(lou)面性(xing)能充分發揮(hui)鋼的(de)(de)良好的(de)(de)抗拉強(qiang)度(du)和延性(xing)及混凝(ning)土優良的(de)(de)抗壓(ya)(ya)強(qiang)度(du)和較大(da)的(de)(de)剛度(du)。壓(ya)(ya)型板(ban)(ban)(ban)(ban)表面壓(ya)(ya)紋使(shi)樓(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)與混凝(ning)土之間產生(sheng)大(da)的(de)(de)結合力，使(shi)二者(zhe)形(xing)成(cheng)整體，配以加勁肋，使(shi)樓(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)系統(tong)具(ju)有(you)高強(qiang)承(cheng)(cheng)載力。在(zai)(zai)懸臂條件下，樓(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)僅作為性(xing)模板(ban)(ban)(ban)(ban)。懸挑的(de)(de)長度(du)可根據樓(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)的(de)(de)截(jie)面特性(xing)來(lai)定。為了防止懸挑板(ban)(ban)(ban)(ban)的(de)(de)開裂，需在(zai)(zai)支(zhi)座處依結構工程(cheng)師的(de)(de)設(she)計配上(shang)負筋。

鍍鋅管廠家熱浸鍍鋅鋼板將薄鋼板浸入熔解的鋅槽中，使其表面粘附一層鋅的薄鋼板。目前主要采用連續鍍鋅工藝生產，即把成卷的鋼板連續浸在熔解有鋅的鍍槽中制成鍍鋅鋼板;合金化鍍鋅鋼板。德陽攀華鍍鋅管這種(zhong)鋼板(ban)也是用熱浸(jin)(jin)法(fa)制造，但在出槽后，立(li)即(ji)把它加熱到500 ℃左右，使其生成鋅(xin)和鐵的(de)(de)合金被膜。這種(zhong)鍍(du)(du)(du)鋅(xin)板(ban)具(ju)有良(liang)好(hao)的(de)(de)涂料(liao)的(de)(de)密著性(xing)和焊(han)接(jie)性(xing);電鍍(du)(du)(du)鋅(xin)鋼板(ban)。用電鍍(du)(du)(du)法(fa)制造這種(zhong)鍍(du)(du)(du)鋅(xin)鋼板(ban)具(ju)有良(liang)好(hao)的(de)(de)加工(gong)性(xing)。但鍍(du)(du)(du)層較薄，耐腐蝕性(xing)不如熱浸(jin)(jin)法(fa)鍍(du)(du)(du)鋅(xin)板(ban);單面鍍(du)(du)(du)和雙面差鍍(du)(du)(du)鋅(xin)鋼板(ban)。單面鍍(du)(du)(du)鋅(xin)鋼板(ban)，即(ji)只在一面鍍(du)(du)(du)鋅(xin)的(de)(de)產品。在焊(han)接(jie)、涂裝、防銹處理、加工(gong)等方面，具(ju)有比(bi)雙面鍍(du)(du)(du)鋅(xin)板(ban)好(hao)的(de)(de)適應(ying)性(xing)。
