ru tsev brackets yog tas li raug rau lub ru tsev ib puag ncig, ntsib kev cov nyom los nag, av noo, kub hloov, thiab txawm corrosive cua. Yog li ntawd, kev xaiv cov khoom tseem ceeb heev.
1. Cov khoom siv hauv paus: Cov khoom tseem ceeb yog hlau, uas muaj lub zog siab thiab zoo thauj khoom -cov kabmob muaj peev xwm. Cov khoom siv feem ntau suav nrog kub-dip galvanized steel thiab aluminium-zinc coated steel. Aluminium-zinc coated steel feem ntau ua tau zoo nyob rau hauv cov nqe lus ntawm corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv resisting ntug corrosion diffusion.
2. Anti-Coating Txheej: Ntxiv rau cov hlau plating ntawm cov khoom siv hauv paus, cov txheej txheem ntxiv, xws li cov xim polyester, qee zaum siv rau saum npoo ntawm purlins los muab ntau yam xim xaiv los yog kev tiv thaiv ntxiv, tso cai rau lawv kom haum rau cov xim ntawm cov corrugated steel vov tsev.
3. Khoom Thickness: Lub thickness ntawm cov khoom siv bracket (feem ntau ntsuas hauv millimeters) ncaj qha cuam tshuam rau nws lub zog thiab rigidity. Lub thickness yuav tsum tau xaiv scientific raws li load xam, purlin ncua, thiab lwm yam. Thicker tsis yog ib txwm zoo dua, tab sis nws yuav tsum tsis txhob qis dua cov kev cai tsim kev nyab xeeb.
