1. Visually hais lus, wrought hlau guardrails yog complex thiab varied, thaum zinc steel guardrails yog yooj yim thiab zoo nkauj. Qhov saum npoo ntawm wrought hlau guardrail yog ntxhib; Yooj yim rau xeb thiab stain, nrog cov xim nplua nuj uas tuaj yeem sib phim raws li cov neeg siv khoom xav tau.
2. Nyob rau hauv cov nqe lus ntawm installation thiab sib dhos txoj kev, lub wrought hlau guardrail txais ib tug tag nrho welded kev twb kev txuas txoj kev. Tsis tas li ntawd, cov ntaub ntawv hlau wrought muaj ntau yam, ua rau kev sib dhos nyuaj thiab yooj yim rau xeb. Lub zinc steel guardrail txais kev xuas nrig ntaus vuam, txuas accessories thiab bolts. Thaum lub sij hawm installation, tsuas yog txiav cov khoom raws li qhov loj me thiab txuas cov khoom siv, uas yooj yim, ceev thiab ruaj khov.
3. Nyob rau hauv cov nqe lus ntawm huab cua tsis kam, wrought hlau guardrails yog pleev xim rau tiv thaiv corrosion thiab xeb. Feem ntau, ib lub tsho ntawm cov xim tsuas tuaj yeem kav ntev txog 35 xyoo. Cov xim txheej yog feem ntau fading thiab tev. Zinc steel guardrails siv kub-dip zinc substrate rau tshuaj tiv thaiv corrosion, tiv thaiv lub substrate los ntawm xeb los ntawm sab hauv tawm. Cov nplua nuj zinc phosphating txhim kho qhov adhesion ntawm txheej thiab substrate. Organic zinc epoxy hmoov txheej txhim khu kev tiv thaiv corrosion thiab cuam tshuam tsis kam. Poly xim hmoov txheej, tiv taus UV rays, ntev thiab luv stains, thiab nws tus kheej ntxuav ntawm qhov chaw. Cov txheej txheem ntau txheej los tiv thaiv corrosion ntawm zinc steel profiles kom ntseeg tau tias zinc steel guardrails muaj zog tiv thaiv huab cua, tuaj yeem tswj lawv cov xim tsis muaj fading, thiab yuav tsis xeb rau 30 xyoo.
