Q: Dab tsi yog cov khoom stamping ntawm Q235 kauj?
A: Cov khoom stamping yog qhov nruab nrab. Nws tsuas yog tsim nyog rau qhov yooj yim ntiav - kos qhov chaw. Rau kev sib sib zog nqus sib sib zog nqus- kos qhov chaw, txias- dov tob- kos hlau (xws li DC04, DC06) yuav tsum tau siv.
Q: Q235 puas tuaj yeem galvanized?
A: Yog. Kub-dip galvanizing lossis electro-galvanizing tuaj yeem txhim kho nws cov corrosion kuj. Galvanized Q235 kauj feem ntau yog siv nyob rau hauv sab nraum zoov steel qauv.
Q: Puas yog cov khoom siv hluav taws xob ntawm Q235 coil cuam tshuam los ntawm nws cov tuab?
A: Yog. Raws li lub thickness nce, lub zog tawm los thiab tensile zog txo me ntsis, thiab elongation kuj txo. Qhov no yog vim lub thickness ntawm cov hlau.
Q: Qhov txawv ntawm Q235 kauj thiab Q235 steel phaj yog dab tsi?
A: Cov khoom tseem ceeb yog tib yam. Qhov sib txawv yog nyob rau hauv daim ntawv xa khoom: coils raug xa mus rau hauv cov coils, nrog ntev ntev, yooj yim rau qib thiab ua tiav; steel daim hlau yog xa ncaj nraim, nrog rau qhov ntev, thiab tuaj yeem siv ncaj qha.
Q: Dab tsi yog lwm txoj hauv kev rau Q235 steel kauj?
A: Rau cov ntawv thov uas yuav tsum muaj lub zog qis, SPHC kub- dov steel kauj tuaj yeem siv tau; rau cov ntawv thov uas yuav tsum muaj zog dua, Q355 steel kauj tuaj yeem siv tau; rau cov ntawv thov uas xav tau ntau dua rau qhov zoo ntawm qhov chaw thiab kev ua haujlwm stamping, txias -khoov steel coils xws li SPCC thiab DC01 tuaj yeem siv.
