合(he)金化鍍(du)(du)鋅不銹鋼沖(chong)孔(kong)(kong)螺旋(xuan)管。不銹鋼沖(chong)孔(kong)(kong)螺旋(xuan)管也是用熱(re)浸法制(zhi)造，但在出槽(cao)后，立即把(ba)它加熱(re)到500℃左(zuo)右，使其生成鋅和(he)鐵的合(he)金圓孔(kong)(kong)網被膜。這種鍍(du)(du)鋅板具有出色的涂料的密(mi)著(zhu)性和(he)焊接性的圓孔(kong)(kong)網、熱(re)浸鍍(du)(du)鋅不銹鋼沖(chong)孔(kong)(kong)螺旋(xuan)管。

    將(jiang)薄不銹鋼(gang)(gang)沖孔螺(luo)旋管浸入熔(rong)解(jie)的(de)鋅(xin)槽(cao)中，使(shi)其表面粘(zhan)附一層鋅(xin)的(de)薄鋼(gang)(gang)板圓孔網。現在首要選用連(lian)續鍍(du)(du)鋅(xin)工(gong)藝出產(chan)，即把成(cheng)(cheng)卷的(de)鋼(gang)(gang)板連(lian)續浸在熔(rong)解(jie)有鋅(xin)的(de)鍍(du)(du)槽(cao)中制成(cheng)(cheng)鍍(du)(du)鋅(xin)鋼(gang)(gang)板；電鍍(du)(du)鋅(xin)鋼(gang)(gang)板。用電鍍(du)(du)法制造這種鍍(du)(du)鋅(xin)鋼(gang)(gang)板具有出色的(de)加工(gong)性。

    但鍍(du)層較(jiao)薄(bo)，耐(nai)腐(fu)蝕性不(bu)如(ru)熱浸(jin)法(fa)鍍(du)鋅(xin)板；沖孔板合(he)金(jin)、復合(he)鍍(du)鋅(xin)鋼板。它是用(yong)(yong)鋅(xin)和其他金(jin)屬如(ru)鉛、鋅(xin)制成(cheng)合(he)金(jin)乃(nai)至(zhi)復合(he)鍍(du)成(cheng)的不(bu)銹鋼沖孔螺旋管。這種鋼板圓孔網既具有(you)出色的防銹功用(yong)(yong)，又有(you)出色的涂裝功用(yong)(yong)。

    單(dan)(dan)面(mian)(mian)(mian)(mian)(mian)鍍(du)和雙(shuang)面(mian)(mian)(mian)(mian)(mian)差鍍(du)鋅(xin)(xin)不銹鋼(gang)(gang)沖孔螺旋管。單(dan)(dan)面(mian)(mian)(mian)(mian)(mian)鍍(du)鋅(xin)(xin)鋼(gang)(gang)板，即只在(zai)(zai)一面(mian)(mian)(mian)(mian)(mian)鍍(du)鋅(xin)(xin)的產(chan)品。在(zai)(zai)焊接(jie)、涂(tu)裝、防(fang)銹處理、加(jia)工(gong)等方(fang)面(mian)(mian)(mian)(mian)(mian)，具有(you)比雙(shuang)面(mian)(mian)(mian)(mian)(mian)鍍(du)鋅(xin)(xin)板更好的適應性。為打敗單(dan)(dan)面(mian)(mian)(mian)(mian)(mian)未(wei)涂(tu)鋅(xin)(xin)的缺(que)點，又(you)有(you)一種在(zai)(zai)另(ling)面(mian)(mian)(mian)(mian)(mian)涂(tu)以(yi)薄層(ceng)鋅(xin)(xin)的鍍(du)鋅(xin)(xin)板，即雙(shuang)面(mian)(mian)(mian)(mian)(mian)差鍍(du)鋅(xin)(xin)板。
