Q235 cov chaw thov tseem ceeb?
A: Kev tsim cov qauv hlau (kab kab, kab, kab, kab, scaffolding), cov tshuab dav dav (txhawb nqa, hauv paus, vaj tse), qis- cov kav dej siab, qhov chaw stamped, kho vajtse.
Q235 tsis haum rau qhov xwm txheej twg?
A: Heavy-duty/large-span structures, low-temperature dynamic loads below -20℃, high-temperature (>300 degree), corrosive heev, thiab siab - hnav- tiv taus xwm txheej.
Q235 tus corrosion kuj?
A: Tsis zoo corrosion kuj, nquag rusting; yuav tsum tau galvanizing, painting, passivation, thiab lwm yam los tiv thaiv- kev kho corrosion.
Q235 tuaj yeem siv rau hauv cov hlab ntsha siab?
A: Tsuas yog rau qis- siab, ib txwm- qhov kub thiab txias, tsis yog - cov thawv ntim khoom siv hluav taws xob. High-siab / qis-kub ntim yuav tsum tau tshwj xeeb steel.
Q235 tuaj yeem hloov siab -lub zog steel?
A: Kev hloov pauv tsawg yog ua tau nyob rau hauv me me - ncua, qis- kev ntxhov siab, thiab cov xwm txheej zoo li qub; nws tsis tuaj yeem hloov siab - lub zog steel nyob rau hauv hnyav / dynamic loads thiab yuav tsum tau muab xam.
