1. Siv tau ib puag ncig muaj feem xyuam: huab cua huab cua
Inland Qus - pite piined atmospheres: Cov chaw uas muaj cov av noo qis, tsis muaj qhov tso pa tawm (og, cov plua tshauv pa) Nws zam dhau sai corrosion los ntawm cov pa phem lossis muaj noo noo.
Cov chaw me me noo noo: Cov cheeb tsam nrog cov dej nag ua ke (tab sis tsis muaj cov dej qab zib ntev ntev) thiab cov ntsev kom huv, tsis yog {{ntug dej hauv nroog loj). Nws tsis tuaj yeem tiv thaiv siab heev -, cov pa dej hiav txwv), raws li cov pa roj av (chlite)
Sab Hauv Tsev Semi -}} QHIB QHOV CHAW: Ib puag ncig muaj kev tiv thaiv zoo thiab tsis muaj dej ncaj nraim (piv txwv li, qhib}} huab cua canopies hauv av log logistics). Nws tsis haum rau ntxuaj, tsis zoo cua tshuab sab hauv tsev (piv txwv li, cov hauv paus, cov dej phwj cov dej tuaj yeem ua rau cov corrosion.
2. Lub sij hawm haum: tsawg {{{1} log, tsis - tseem ceeb qauv
Lub teeb yuag thiab cov qauv toj roob hauv pes:
Qhib - huab cua Pavilions, vaj trellises, thiab qis} Cov neeg taug kev ntawm cov neeg taug kev lossis cov neeg taug kev cov nyom, tsis muaj cov rog hnyav).
Hniav tawv nqaij steel (piv txwv li, kos duab puab, kos npe) uas xav tau kev rov qab ua kom muaj zog ntau dua li cov xeeb ceem siab tshaj li.
Tsawg - phoo} LOAD AUXILIARY:
Txhawb kom muaj me me - scad point panels (tsis {{1} ntug dej hiav txwv zoo li qub (muaj kev hnyav
Cov neeg tiv thaiv kev nyob deb nroog txoj kev lossis zej zog sab hauv txoj kev (tsis siab}}} Kev mob tsheb loj hauv nroog) uas tsuas yog yuav tsum tawm tsam cov quab yuam me thiab cov khoom siv hluav taws xob.
Lub teeb kev lag luam thiab cov chaw cia khoom:
Ntas rau me me qhib - huab cua cia cov khoom siv (}
Tsis - siab tso tsheb hlau luam me (piv txwv li, cov pob zeb hauv av tso tawm) uas tsis tau siv lub siab me me lossis cov khoom siv corrosive.
Tsis ntev lossis qis {{} Lifpan qauv qauv:
Cov chaw tsim khoom ib ntus, cov neeg taug kev hauv neeg taug kev rau kev tsim kho, lossis cov khoom siv ib ntus ib ntus. These structures have short service lives (usually 1–5 years), and Q235NH's basic corrosion resistance and low cost meet their short-term use needs without overinvesting in high-grade steels.
Txwv qhov tseem ceeb kom nco ntsoov
Heavy-load structures (eg, bridge main beams, high-rise building steel frames) due to insufficient mechanical strength.
Harsh thaj chaw (xws li ntug dej hiav txwv siab - cov chaw ntsev, dej phwj tuaj yeem tiv thaiv tsis tau cov xov xwm.
Kev ua haujlwm siab lossis cov rog nrog kev qaug zog nruj tiv thaiv (piv txwv li, cua tshuab luam yeeb yaj kiab los qhib cov khoom siv sib xyaw lossis sab hauv.
