Galvanized tsim: Raws li peb txhua tus paub, txoj kev guardrails yog coated nrog ib txheej ntawm zinc, uas tsis tsuas yog muab kev tiv thaiv rau lub guardrail, tab sis kuj ncua nws cov kev pab cuam lub neej. Cov txheej txheej ntawm galvanized tsim yog tsim los ntawm kub-dip zinc txheej, zinc nplua nuj phosphating txheej, organic zinc nplua nuj epoxy hmoov txheej, thiab polyester "flawless" xim hmoov txheej, endowing txoj kev guardrails nrog zoo heev corrosion kuj, zoo noo noo tsis kam, tshuaj tiv thaiv, thiab super muaj zog UV stability.
Xim muaj nuj nqi tsim: Qhov tseeb, xim xim ntawm txoj kev guardrails kuj tseem ceeb heev. Txhawm rau ua kom tau raws li cov kev xav tau ntawm kev nyab xeeb kev nyab xeeb thiab kev tsheb ciav hlau, raws li cov tsheb khiav tam sim no ntawm cov xim liab, dawb, daj, ntsuab, thiab dub, ntsuab hloov mus rau xiav, tsim tsib xim xim liab, xiav, dawb. , daj, thiab dub. Ntau qhov sib xyaw ua ke ntawm cov xim muaj feem xyuam rau cov kev taw qhia, kev tsav tsheb, thiab cov lus ceeb toom yog tsim thiab teeb tsa ntawm cov tsheb thauj neeg mob hauv nroog, ua kom cov ntsiab lus meej thiab meej ntawm cov lus hauv nroog uas yooj yim to taub ntawm ib nrais muag.
Cov saum toj no yog cov ntsiab lus tseem ceeb ntawm txoj kev guardrails, vam tias yuav pab tau rau txhua tus.
