Ua ntej, kev siv cov qauv sib txawv, kev ua raws li European tus qauv H-beam steel qauv EN10034-1993 EN10025-3-2004 thiab kev ua raws li lub teb chaws tus qauv yog GB / T706-2016;
Qhov thib ob, cov khoom sib txawv, ob cov ntaub ntawv tsis yog tib yam khoom S235JR European txheem H-beam steel sib haum rau lub teb chaws tus qauv qauv steel Q235B European txheem H-beam steel khoom S355J0 sib haum mus rau lub teb chaws tus qauv qauv steel Q355C European txheem H-beam steel khoom S355J2 sib xws rau lub teb chaws tus qauv qauv steel Q355D European H-beam steel khoom S355JR sib haum mus rau lub teb chaws tus qauv steel Q355B European H-beam steel khoom S355JR sib xws rau lub teb chaws tus qauv steel Q355D European H-beam steel khoom S355JR sib haum rau lub teb chaws tus qauv qauv steel Q355B Q355B.
Thib peb, txhua tus qauv sawv cev rau cov qauv sib xws ntawm qhov loj me thiab cov duab geometry European tus qauv H-beam steel tuaj yeem muab faib ua ntau pawg raws li cov ntaub ntawv sib txawv, xws li cov pa roj carbon zoo tib yam steel, tsis tshua muaj hlau alloy high-strength steel, Kub dov welded steel, thiab lwm yam. Cov qauv sib txawv thiab cov khoom siv ntawm European tus qauv H-beam steel muaj qhov sib txawv load-bearing muaj peev xwm khoov tsis kam thiab corrosion kuj.
