Cov square thiab lub voj voos hollow seem ua los ntawm cov hlau me Q235 feem ntau yog siv rau hauv kev tsim vaj tsev, kev txhawb nqa, thiab kev siv vaj tse. Cov hlab no paub txog lawv cov kav ntev, yooj yim ntawm fabrication, thiab haum rau ntau yam vuam thiab tsim cov txheej txheem. Lub npe Q235 qhia tias cov hlau yog tsim los ntawm cov pa roj carbon me me.
