Galvanized daim kab xevhnub rov qab mus rau thaum ntxov xyoo pua 19th. Thaum lub sijhawm ntawd, nrog rau kev nce qib ntawm Industrial Revolution, kev tsim khoom thiab kev siv cov hlau tau nce sai heev. Vim tias npua hlau thiab hlau zoo li corrode thaum raug ya raws thiab oxygen, cov kws tshawb fawb tau pib tshawb nrhiav txoj hauv kev los tiv thaiv corrosion.
Nyob rau hauv 1836, Fabkis chemist Antoine Henri Becker thawj zaug npaj lub tswv yim ntawm txheej zinc rau saum npoo ntawm hlau los yog hlau los tiv thaiv corrosion. Txoj kev no hu uakub dip galvanizing. Nrog rau txoj kev loj hlob ntawm cov cuab yeej no, galvanized daim kab xev tau maj mam tsim thiab siv.
Nyob rau hauv lub xyoo pua 20th, nrog kev nce qib ntawm kev siv tshuab galvanizing, ntau yam txheej txheem xws li electroplating thiab kub plating tau tshwm sim ib tom qab, yog li ntawd cov kev ua tau zoo thiab kev tiv thaiv corrosion ntawm galvanized daim kab xev tau raug txhim kho tas li. Cov kev nce qib no tau txhawb txoj kev siv dav dav ntawm galvanized daim kab xev hauv ntau qhov kev lag luam xws li kev tsim kho, tsheb, thiab cov khoom siv hauv tsev, tsim cov lag luam paub tab peb pom niaj hnub no.

Galvanized daim kab xev tau dav siv nyob rau hauv ntau lub lag luam vim nws zoo heev corrosion kuj thiab zoo workability. Hauv kev tsim kho, daim kab xev galvanized yog siv hauv cov qauv steel, lub ru tsev thiab phab ntsa, uas tuaj yeem ua kom ntev lub neej kev pab cuam. Hauv kev lag luam tsheb, galvanized daim kab xev yog siv los uatsim khoom lub cevlos txhim kho corrosion kuj thiab kev nyab xeeb. Cov cuab yeej siv thiab rooj tog kev lag luam kuj tseem siv los ua cov khoom siv tseem ceeb los txhim kho cov kav ntev thiab kev zoo nkauj ntawm lawv cov khoom.
Nyob rau hauv lub neej yav tom ntej, nrog cov kev cai ib puag ncig nruj zuj zus thiab cov qauv ntawm lub tsev ntsuab thiab kev tsim kho kom ruaj khov, kev lag luam xav tau rau cov hlua khi galvanized yuav tsum txuas ntxiv mus. Txoj kev loj hlob ntawm cov ntaub ntawv tshiab thiab kev ua haujlwm thev naus laus zis yuav ntxiv mustxhim kho kev ua haujlwm ntawm galvanized daim kab xevthiab nthuav nws daim ntawv thov teb. Yog li ntawd, tag nrho txoj kev loj hlob zeem muag ntawm galvanized daim kab xev yog qhov zoo tshaj plaws, thiab nws tau dhau los ua cov khoom tseem ceeb hauv ntau yam lag luam.
