鍍(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)是(shi)為防止鋼(gang)板(ban)(ban)(ban)(ban)表面遭受腐蝕(shi)，延長其(qi)使用(yong)壽命(ming)，在(zai)鋼(gang)板(ban)(ban)(ban)(ban)表面涂(tu)以(yi)一(yi)層金(jin)(jin)屬(shu)鋅(xin)(xin)，這種(zhong)(zhong)涂(tu)鋅(xin)(xin)的(de)(de)(de)薄鋼(gang)板(ban)(ban)(ban)(ban)稱為鍍(du)鋅(xin)(xin)板(ban)(ban)(ban)(ban)。鋼(gang)板(ban)(ban)(ban)(ban)也是(shi)用(yong)熱(re)浸(jin)法制(zhi)(zhi)造，但(dan)在(zai)出槽(cao)后，立即把(ba)它(ta)(ta)加熱(re)到500℃左(zuo)右(you)，使其(qi)生成(cheng)鋅(xin)(xin)和(he)鐵(tie)的(de)(de)(de)合金(jin)(jin)被膜(mo)。這種(zhong)(zhong)鍍(du)鋅(xin)(xin)卷具有良好的(de)(de)(de)涂(tu)料(liao)的(de)(de)(de)密(mi)著(zhu)(zhu)性(xing)和(he)焊接性(xing)。合金(jin)(jin)化鍍(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)。這種(zhong)(zhong)鋼(gang)板(ban)(ban)(ban)(ban)也是(shi)用(yong)熱(re)浸(jin)法制(zhi)(zhi)造，但(dan)在(zai)出槽(cao)后，立即把(ba)它(ta)(ta)加熱(re)到500℃左(zuo)右(you)，使其(qi)生成(cheng)鋅(xin)(xin)和(he)鐵(tie)的(de)(de)(de)合金(jin)(jin)被膜(mo)。這種(zhong)(zhong)鍍(du)鋅(xin)(xin)板(ban)(ban)(ban)(ban)具有良好的(de)(de)(de)涂(tu)料(liao)的(de)(de)(de)密(mi)著(zhu)(zhu)性(xing)和(he)焊接性(xing)。熱(re)浸(jin)鍍(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)。將薄鋼(gang)板(ban)(ban)(ban)(ban)浸(jin)入熔解的(de)(de)(de)鋅(xin)(xin)槽(cao)中(zhong)，使其(qi)表面粘附一(yi)層鋅(xin)(xin)的(de)(de)(de)薄鋼(gang)板(ban)(ban)(ban)(ban)。目(mu)前(qian)主要采用(yong)連續鍍(du)鋅(xin)(xin)工藝生產，即把(ba)成(cheng)卷的(de)(de)(de)鋼(gang)板(ban)(ban)(ban)(ban)連續浸(jin)在(zai)熔解有鋅(xin)(xin)的(de)(de)(de)鍍(du)槽(cao)中(zhong)制(zhi)(zhi)成(cheng)鍍(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)。合金(jin)(jin)、復合鍍(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)。它(ta)(ta)是(shi)用(yong)鋅(xin)(xin)和(he)其(qi)他(ta)金(jin)(jin)屬(shu)如鉛、鋅(xin)(xin)制(zhi)(zhi)成(cheng)合金(jin)(jin)乃(nai)至復合鍍(du)成(cheng)的(de)(de)(de)鋼(gang)板(ban)(ban)(ban)(ban)。這種(zhong)(zhong)鋼(gang)板(ban)(ban)(ban)(ban)既具有防銹性(xing)能，又有良好的(de)(de)(de)涂(tu)裝(zhuang)性(xing)能。

攀華鍍鋅價格鋼筋桁架樓承板完成了機械化出產，有利于鋼筋擺放距離均勻、混凝土保護層厚度共同，提高了樓板的施工質量。裝配式鋼筋桁架樓承板可明顯削減現場鋼筋綁扎工程量，加速施工進度，添加施工確保，完成文明施工。鍍鋅價格裝配(pei)(pei)式模板(ban)和連(lian)接件拆(chai)裝便利，可屢次(ci)重(zhong)復使用(yong)，節(jie)省鋼(gang)材(cai)，契合國家節(jie)能(neng)(neng)環保(bao)的(de)要求。鋼(gang)構自主(zhu)研制(zhi)的(de)產(chan)品(pin)配(pei)(pei)套自動化出產(chan)設備，大(da)大(da)提高了勞動出產(chan)率，有用(yong)降低了產(chan)品(pin)成(cheng)本，并編制(zhi)了產(chan)品(pin)出產(chan)企(qi)業規范、規劃手(shou)冊(ce)和節(jie)點(dian)構造圖(tu)集(ji)以及施工手(shou)冊(ce)。該產(chan)品(pin)經過(guo)浙江大(da)學土(tu)木工程(cheng)測試中心檢測，并經過(guo)多項(xiang)工程(cheng)使用(yong)，各項(xiang)功能(neng)(neng)可以滿意現澆鋼(gang)筋混凝(ning)土(tu)樓板(ban)承載力和變形的(de)要求。

重慶樓承板(ban)(ban)(ban)(ban)的(de)鍍(du)(du)鋅(xin)(xin)量沒有一個具體(ti)的(de)標準(zhun)，制作(zuo)壓(ya)型鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)的(de)冷(leng)軋鋼(gang)(gang)(gang)卷須連續熱浸鍍(du)(du)鋅(xin)(xin)（或鍍(du)(du)鋁(lv)鋅(xin)(xin)），鍍(du)(du)（鋁(lv)）鋅(xin)(xin)量視設計(ji)要(yao)求而定。樓承板(ban)(ban)(ban)(ban)用壓(ya)型鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)宜選(xuan)擇熱浸鍍(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。不允(yun)許使用電鍍(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)，電鍍(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)僅(jin)在(zai)(zai)基材表面形成保(bao)護層，防腐能力有限。目前(qian)市場上有鍍(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)（鍍(du)(du)層含鋁(lv)5%或55%），在(zai)(zai)酸性環境(jing)下(xia)的(de)防腐效果由于熱浸鍍(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)，但(dan)在(zai)(zai)混凝土(tu)的(de)堿性條(tiao)件(jian)下(xia)，鍍(du)(du)鋁(lv)鋅(xin)(xin)的(de)防腐蝕性能低于熱浸鍍(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)，且鋁(lv)會和混凝土(tu)發生(sheng)反應，并降低混凝土(tu)與鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)的(de)粘結性能。因此參考國外規范，及國內外工程，行家壓(ya)型鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)不建議使用鍍(du)(du)鋁(lv)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。
