Txoj kev loj guardrails tau muab faib ua ob hom raws li lawv cov yam ntxwv tsim: welded hlau mesh guardrails thiab saw txuas laj kab guardrails. Ob hom yog dav siv rau kev tiv thaiv. Welded hlau mesh guardrails yog tsim los ntawm welding hlau hlau, txias -galvanized hlau hlau, los yog kub-galvanized hlau hlau siv lub welded hlau mesh tshuab, ua raws li los ntawm dabtsi yog khoov, hmoov txheej, los yog PVC txheej, thiab lwm yam txheej txheem. Lawv yog cov corrosion-resistant, zoo nkauj txaus nyiam, thiab muab kev tiv thaiv zoo. Cov hlua txuas laj kab thaiv yog tsim los ntawm kev xaws ntau yam hlau hlau, suav nrog PVC xaim, txias-galvanized hlau, thiab kub-galvanized hlau, siv lub tshuab saw txuas laj kab. Lawv muaj kev cuam tshuam heev-tiv taus, zoo nkauj txaus nyiam, corrosion{11}}resistant, thiab muaj kev tiv thaiv zoo.
Cov khoom lag luam zoo nkauj zoo nkauj, ruaj khov, tsis yog -deformable, thiab nrawm rau nruab, ua rau nws yog ib qho khoom siv hlau tiv thaiv zoo tshaj plaws. Nws tuaj yeem siv los ua laj kab mus tas li lossis ua ib qho kev thaiv ib ntus, tsuas yog los ntawm kev siv ntau txoj hauv kev kho cov ncej. Nws muaj kev tiv thaiv corrosion, kev laus tiv thaiv, hnub tiv thaiv, thiab huab cua tsis kam. Kev tiv thaiv corrosion, electroplating, kub-dip galvanizing, hmoov txheej, thiab dip txheej tuaj yeem siv.
