鍍(du)鋅(xin)鋼管(guan)(guan),是一般稱的(de)冷鍍(du)管(guan)(guan)，采用電鍍(du)工(gong)藝(yi)，只在鋼管(guan)(guan)的(de)外壁(bi)鍍(du)鋅(xin)，鋼管(guan)(guan)的(de)內壁(bi)沒(mei)有(you)鍍(du)鋅(xin);熱鍍(du)鋅(xin)鋼管(guan)(guan)采用的(de)是熱浸鍍(du)鋅(xin)工(gong)藝(yi)，鋼管(guan)(guan)的(de)內、外壁(bi)都(dou)有(you)鋅(xin)層。

　　制造工藝區別：鍍鋅鋼管和無縫鋼管是鋼(gang)管(guan)(guan)(guan)(guan)(guan)兩種范疇，鍍(du)鋅(xin)(xin)是指鋼(gang)管(guan)(guan)(guan)(guan)(guan)表(biao)面進行(xing)了鍍(du)鋅(xin)(xin)處理，有可能(neng)(neng)是焊(han)接管(guan)(guan)(guan)(guan)(guan)，也(ye)可能(neng)(neng)是無(wu)縫(feng)管(guan)(guan)(guan)(guan)(guan)，無(wu)縫(feng)是指鋼(gang)管(guan)(guan)(guan)(guan)(guan)的(de)(de)制造工(gong)藝，有焊(han)接和(he)無(wu)縫(feng)之(zhi)分。鍍(du)鋅(xin)(xin)管(guan)(guan)(guan)(guan)(guan)耐腐蝕些，無(wu)縫(feng)鋼(gang)管(guan)(guan)(guan)(guan)(guan)能(neng)(neng)承受更高的(de)(de)壓力。 鍍(du)鋅(xin)(xin)鋼(gang)管(guan)(guan)(guan)(guan)(guan)由于(yu)有鋅(xin)(xin)的(de)(de)保護(hu)，不容易生銹，鍍(du)鋅(xin)(xin)鋼(gang)管(guan)(guan)(guan)(guan)(guan)比無(wu)縫(feng)鋼(gang)管(guan)(guan)(guan)(guan)(guan)輕(qing)，如(ru)果(guo)是用(yong)(yong)于(yu)陽(yang)(yang)臺(tai)(tai)的(de)(de)話(hua)，最好(hao)用(yong)(yong)鍍(du)鋅(xin)(xin)光管(guan)(guan)(guan)(guan)(guan)，無(wu)縫(feng)鋼(gang)管(guan)(guan)(guan)(guan)(guan)太用(yong)(yong)不太適(shi)合用(yong)(yong)于(yu)陽(yang)(yang)臺(tai)(tai)，因為(wei)無(wu)縫(feng)鋼(gang)管(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)壁厚，自然重量(liang)就重，而且無(wu)縫(feng)鋼(gang)管(guan)(guan)(guan)(guan)(guan)的(de)(de)成本(ben)要(yao)比鍍(du)鋅(xin)(xin)鋼(gang)管(guan)(guan)(guan)(guan)(guan)的(de)(de)成本(ben)要(yao)高，還有鍍(du)鋅(xin)(xin)鋼(gang)管(guan)(guan)(guan)(guan)(guan)很耐用(yong)(yong)，使(shi)用(yong)(yong)年(nian)限要(yao)遠遠超過無(wu)縫(feng)鋼(gang)管(guan)(guan)(guan)(guan)(guan)。如(ru)果(guo)質量(liang)過硬(ying)，使(shi)用(yong)(yong)二十多年(nian)應該不成問題(ti)，當然焊(han)接和(he)油漆也(ye)要(yao)做好(hao)，不讓會影響鍍(du)鋅(xin)(xin)鋼(gang)管(guan)(guan)(guan)(guan)(guan)的(de)(de)使(shi)用(yong)(yong)年(nian)限。用(yong)(yong)途(tu)區別：鍍(du)鋅(xin)(xin)鋼(gang)管(guan)(guan)(guan)(guan)(guan)一般(ban)就是用(yong)(yong)來做柵欄、圍欄、護(hu)欄、陽(yang)(yang)臺(tai)(tai)護(hu)欄的(de)(de)。廣泛使(shi)用(yong)(yong)于(yu)市政工(gong)程、道路、工(gong)廠(chang)、學校(xiao)、開發區、園(yuan)林、廣場(chang)、小(xiao)區等場(chang)所。
