Yuav kom txhim kho kev nyab xeeb ntawm lub tsev, Hong Kong tau qhia meej txog cov txheej txheem tag nrho rau kev sivgalvanized av pawg: cov khoom uas muaj cov zinc txheej tuab ntawm ≥ 85 μ m thiab ua raws li GB / T 13912 tus qauv yuav tsum tau xaiv. Kev tshawb fawb geological yuav tsum tau ua ua ntej kev tsim kho, thiab cov neeg ua haujlwm tau ntawv pov thawj yuav tsum siv cov khoom siv tshwj xeeb rau kev teeb tsa tus qauv, tswj hwm qhov ntsug thiab qhov tob faus. Tom qab kev teeb tsa, nws yog qhov tsim nyog los dhau los ntawm kev sim tensile thiab compressive nrog rau kev txheeb xyuas kev ruaj ntseg hluav taws. Cov khoom tsis tsim nyog raug txwv tsis pub nkag mus rau hauv qhov chaw kom tsis txhob muaj kev phom sij ntawm qhov chaw.

Hong Kong tau tsim tsa ib txoj cai tswjfwm mus sij hawm ntev raugalvanized av pawg, yuav tsum tau kuaj xyuas cov khoom uas raug tshem tawm tas li, nce zaus tom qab huab cua hnyav heev, thiab kho cov xeb thiab zinc txheej puas tsuaj raws sijhawm. Tib lub sijhawm, tsim kom muaj phau ntawv teev npe siv, qhia meej txog qhov txwv siab tshaj plaws ntawm lub neej ua haujlwm 30 xyoo, thiab yuam kom hloov cov pawg av uas tas sij hawm lossis puas lawm. Tsoomfwv kuj tseem yuav txhawb nqa kev kuaj xyuas tshwj xeeb thiab kev cob qhia rau cov kws kho mob kom ua tiav lawv qhov zoo tshaj plaws hauv kev tiv thaiv xeb, kev tiv thaiv hluav taws, thiab kev ruaj khov.
