Kev piav qhia:

1. Tus nqi kho mob qis: Tus nqi ntawm kev kub dip galvanizing qis dua li ntawm lwm cov xim pleev xim.

2. Siv Tau Ntev: Cov hlau galvanized kub-dip muaj cov yam ntxwv ntawm qhov ci ntsa iab, txheej zinc sib xws, tsis muaj xau, tsis muaj dej ntws, nplaum zoo thiab tiv taus corrosion zoo. Hauv thaj chaw nyob deb nroog, qhov tuab txheem ntawm cov txheej galvanized kub-dip xeb tuaj yeem khaws cia tau ntau tshaj 50 xyoo yam tsis tas kho; hauv nroog lossis thaj chaw deb ntawm dej hiav txwv, qhov tuab txheem ntawm cov txheej galvanized kub-dip xeb tuaj yeem khaws cia tau 20 xyoo. Nws tsis tas yuav kho.

3. Kev ntseeg tau zoo: Cov txheej galvanized yog cov hlau sib txuas nrog cov hlau thiab dhau los ua ib feem ntawm cov hlau nto, yog li qhov ruaj khov ntawm cov txheej txheem yog qhov txhim khu kev qha dua.

4. Lub txheej txheej muaj zog tawv: cov txheej galvanized tsim cov qauv hlau tshwj xeeb, uas tuaj yeem tiv taus kev puas tsuaj thaum lub sijhawm thauj mus los thiab siv.

5. Kev tiv thaiv kom zoo: Txhua feem ntawm cov khoom plated tuaj yeem raug galvanized, txawm tias nyob rau hauv kev nyuaj siab, ces kaum ntse thiab qhov chaw zais cia tuaj yeem tiv thaiv tag nrho;

6. Txuag sijhawm thiab txuag zog: cov txheej txheem galvanizing sai dua li lwm txoj kev tsim kho txheej, thiab tuaj yeem zam lub sijhawm xav tau rau kev pleev xim rau ntawm qhov chaw tom qab kev teeb tsa.
