熱鍍鋅方管和電鍍鋅方管兩大類。熱鍍鋅方管有濕法、干法、鉛鋅法、氧化還原法等。不同熱鍍鋅方法的主要區(qū)別在鋼管酸浸清洗后，用什么方法活化管體表面提高鍍鋅質(zhì)量。現(xiàn)生產(chǎn)中主要采用干法和氧化還原法，其特點(diǎn)見表。電鍍鋅的鋅層表面十分光滑致密、組織均勻;具有良好的力學(xué)性能和抗腐蝕能力;鋅耗比熱鍍鋅低60%～75%。電鍍鋅在技術(shù)上有一定的復(fù)雜性，但對(duì)單面鍍層，內(nèi)外表面鍍層厚度不同的雙面鍍層，以及薄壁管鍍鋅等皆須采用此法。

焊接電流120-140a之間。通常用φ3.2的焊條，焊接電流宜偏小，焊接頭嚴(yán)格防腐。在鍍鋅鋼板點(diǎn)焊過程中，由于焊接規(guī)范不合理，會(huì)使接頭中殘留部分鋅及鋅鐵合金在熔核結(jié)晶過程中，可能會(huì)形成細(xì)小裂紋或氣孔，殘留鋅較多時(shí)還會(huì)形成軟化組織。 </p> <p> 鍍鋅方管是橫截面為方形，外表鍍鋅的長(zhǎng)形管材，可分為冷鍍鋅方管、熱鍍鋅方管與鍍鋅帶方管。方管的運(yùn)用壽命是沒有詳細(xì)的運(yùn)用年限的，都是依據(jù)運(yùn)用環(huán)境與生產(chǎn)工藝改變的。而鍍鋅方管的鍍鋅層是常用的防腐防銹措施，能夠有用增長(zhǎng)運(yùn)用壽命，尤其是熱鍍鋅方管能夠做到無死角對(duì)方管進(jìn)行防護(hù)，防腐防銹作用也會(huì)好許多。
