熱鍍鋅鋼絲（hot-dip galvanized steel wire）是把各種優(yōu)質(zhì)中碳鋼或優(yōu)質(zhì)高碳鋼經(jīng)酸洗、磷化、拔絲，再熱鍍鋅。

適用范圍
通信系統(tǒng)中，鍍鋅鋼絲適用于電報(bào)、電話、有線廣播 及信號(hào)傳遞等傳輸線路用。
電力系統(tǒng)中，因鋼絲鋅層質(zhì)量較大、較厚，耐蝕性好，可用于線路腐蝕嚴(yán)重電纜 ? 的裝。
物理性能
耐腐蝕、韌性好、彈性好、抗拉強(qiáng)度高。

與冷鍍鋼絲區(qū)別
冷鍍鋅也叫電鍍鋅，是利用電解設(shè)備將管件經(jīng)過除油、酸洗、后放入成分為鋅鹽的溶液中，并連接電解設(shè)備的負(fù)極，在管件的對(duì)面放置鋅版，連接在電解設(shè)備的正極接通電源，利用電流從正極向負(fù)極的定向移動(dòng)就會(huì)在管件上沉積一層鋅，冷鍍管件是先加工后鍍鋅。冷鍍鋅（電鍍鋅）：是在電鍍槽內(nèi)通過電流單向性使鋅逐漸鍍上金屬外表，生產(chǎn)速度慢，鍍層均勻，厚度較薄，通常只有3-15微米，外觀光亮、光滑、美觀度高，耐腐蝕性差，一般幾個(gè)月就會(huì)銹蝕。
熱鍍鋅是由較古老的熱鍍方法發(fā)展而來的，自從1836年法國(guó)把熱鍍鋅應(yīng)用于工業(yè)以來，已經(jīng)有一百七十年的歷史了。然而，熱鍍鋅工業(yè)是近三十年來伴隨冷軋帶鋼的飛速發(fā)展而得到了大規(guī)模發(fā)展。
熱鍍鋅板的生產(chǎn)工序主要包括：原板準(zhǔn)備→鍍前處理→熱浸鍍→鍍后處理→成品檢驗(yàn)等。按照習(xí)慣往往根據(jù)鍍前處理方法的。
不同把熱鍍鋅工藝分為線外退火和線內(nèi)退火兩大類，即濕法（單張鋼板熱鍍鋅法）、線外退火（單張鋼板熱鍍鋅法）、熱鍍鋅 惠林（Wheeling）法（帶鋼連續(xù)熱鍍鋅法） 、線內(nèi)退火 森吉米爾（Sendzimir）法（保護(hù)氣體法）、改良森吉米爾法、美鋼聯(lián)法（同日本川崎法）、賽拉斯（Selas）法和莎倫（Sharon）法。熱鍍鋅：是在加熱融化的鋅液內(nèi)浸鍍，生產(chǎn)速度快，鍍層厚但不均勻，市場(chǎng)允許的最低厚度45微米，最高可達(dá)300微米以上。顏色較暗，消耗鋅金屬多，與基體金屬形成滲入層，耐蝕性好，室外環(huán)境下熱鍍鋅可以保持幾十年。
熱鍍鋅也稱熱浸鋅，是將鋼鐵工件經(jīng)過除油、除銹，呈現(xiàn)出無污、浸潤(rùn)的表面，立即浸入到預(yù)先將鋅加熱融熔了的鍍槽中去，
在工件表面形成一層鋅鍍層的方法。冷鍍鋅則是將同樣經(jīng)過了除油、除誘，呈現(xiàn)出無污、浸潤(rùn)的工件掛入專門的電鍍槽里的陰極上，陽極用鋅。接通直流電源，陽極上的鋅離子向陰極遷移，并在陰極上放電，使工件鍍上一層鋅層的熱鍍鋅方法。
熱鍍鋅的鍍層較厚，一般為30-60微米，鍍層防腐能力較高。適合于戶外工作的鋼鐵制件，如高速公路圍欄、電力鐵塔、大尺寸緊固件等較為“粗糙”的工件的長(zhǎng)期防銹。
冷鍍鋅絲：是以低碳鋼為芯線，通過拔絲、電鍍鋅工藝加工制成的金屬復(fù)合材料。主要應(yīng)用于制造金屬絲網(wǎng)、高速公路護(hù)攔及建筑工程。
熱鍍鋅絲：該產(chǎn)品應(yīng)用優(yōu)質(zhì)碳素結(jié)構(gòu)鋼，經(jīng)拉拔、熱鍍鋅加工而成。廣泛應(yīng)用于制造金屬絲網(wǎng)、高速公路護(hù)攔及建筑工程。具有鍍層厚，抗腐蝕能力強(qiáng)、鍍層牢固等特點(diǎn)。并可根據(jù)用戶的特殊需求，按行業(yè)標(biāo)準(zhǔn)提供各種規(guī)格的鍍鋅絲。
相對(duì)電鍍鋅，熱鍍鋅生產(chǎn)成本較高但對(duì)環(huán)境的影響比電鍍小。
物理性能：熱鍍鋅鋼絲表面平滑、光潔、沒有裂紋地、節(jié)、起刺、傷痕和銹蝕，鍍鋅層均勻、附著力強(qiáng)、耐腐蝕力持久，韌性和彈性極好。抗拉強(qiáng)度應(yīng)在900Mpa-2200Mpa之間(絲徑Φ0.2mm-Φ4.4mm)。扭轉(zhuǎn)次數(shù)(Φ0.5mm)在20次以上，反復(fù)彎曲應(yīng)在13次以上。
用 途：主要用于種植大棚，養(yǎng)殖場(chǎng)，棉花打包，彈簧及鋼絞線，鋼絲繩的制造.
