Cov txheej txheem tshwj xeeb (H-Beam)
S235jr H-Nqaj yog dav siv rau cov ris luv cov ntsiab lus. Qhov ntau thiab tsawg cov khoom muaj:
Cov qauv ntau thiab tsawg:
125 × 125, 400 × 200 × 8 × 8. × 20, thiab lwm yam nyob ntawm seb: kev sib txawv los ntawm kev sib txawv (400 × 200 × 8 × 8 × 8. 13≈66 kg / m). Cov kev kho deg: Hot-dip Galvanizing lossis pleev xim rau kev txhim kho corrosion.
Kev tsim khoom thiab kev ua
Txoj kev ntau lawm: kub dov, tswj dov lossis ib txwm ua. Cov txheej txheem: kev txiav heev, vuam thiab sib dhos. Cov Khoom Zoo: Muab faib ua fa (qauv) thiab FB (txhim kho) cov qib kawm, uas tuaj yeem zam qhov tsis txaus me xws li khawb lossis dents me me.
Cov qib sib npaug: Q235b (Suav teb); SS400 (Nyiv); A36 (USA).
Kev sib piv nrog lwm qib S235J 0}}}}}}}} {{{4 4}} degree). Q2555 / Q275 (Suav teb): Cov ntsiab lus carbon: ntau dua lossis sib npaug nrog}. 18%), muaj zog loj tab sis lub zog siab kawg tab sis tsis zoo weldability.
Gnee Steel H nqaj Steel Chaw Tsim Tshuaj
Gnee steel tau tsim tsa nyob rau xyoo 2008, peb cov khoom tseem ceeb yog seem steel, lub tsev sib luag, thiab lwm yam. Peb zoo siab los muab koj tus nqi zoo tshaj plaws thiab cov lus qhia. Koj zoo siab tos txais koj mus ntsib peb lub tuam txhab.
