Kev lag luam galvanized yeeb nkab guardrail kev lag luam tsis muaj kev xav tau siab heev rau vuam, thiab yeej ib txwm siv cov pa roj carbon dioxide roj shielded vuam txoj kev.
Txawm li cas los xij, carbon dioxide shielded vuam muaj cov kev xav tau siab rau cov neeg ua haujlwm vuam. Tsis tsuas yog yuav muaj ntau yam teeb meem tshwm sim thaum lub sij hawm vuam, tab sis nws kuj yuav tsum tau polished tom qab vuam.
Nrog rau kev txhim kho txuas ntxiv ntawm kev siv tshuab laser vuam, tshwj xeeb tshaj yog siv dav hauv kev lag luam ntawm tes laser vuam tshuab hauv ntau lub lag luam, laser vuam tshuab tau dhau los ua ntau thiab siv dav hauv cov yeeb nkab galvanized thiab phaj kev lag luam.
Piv nrog rau cov tsoos vuam, laser vuam ntawm cov kav dej galvanized ua rau cov hlaws dai zoo nkauj uas tsis tas yuav polishing, thiab cov kev cai rau cov vuam tsis siab. Txawm tias cov neeg tuaj tshiab tuaj yeem ua tiav cov txiaj ntsig vuam siab.
