Khoom Description
S355J2 thiab S355JR steel cov ntaub ntawv ob leeg ua raws li European steel specficiation BS EN 10025-2 kub dov khoom rau non-alloy structural steels.Cov ob steel qib S355JR thiab S355J2 txawm muaj cov tshuaj zoo sib xws heev thiab yield & tensile lub zog. Qhov txawv yog lawv daim ntawv thov ib puag ncig, cov ntaub ntawv hlau S355J2 yuav tsum tau ua kom tiav cov ntaub ntawv V tsis cuam tshuam qhov ntsuas ntawm rho tawm 20 deg.c, txawm li cas los xij S355JR tsis xav tau.Yog li S355J2 steel cov ntaub ntawv tuaj yeem siv rau hauv qhov kub tsis tshua muaj ib puag ncig xws li cov dej hiav txwv tob.
Ib qho H-beam, tseem hu ua I-beam lossis dav-flange beam, yog hom qauv steel nqaj nrog "H" lossis "Kuv" zoo li thaum saib los ntawm qhov kawg. Nws yog feem ntau siv hauv kev tsim kho thiab engineering los muab kev txhawb nqa rau cov tsev, txuas hniav, thiab lwm yam qauv.
Lub H-beam tau txais nws lub npe los ntawm nws cov duab ntu ntu, uas zoo li tsab ntawv "H" lossis "Kuv." Nws muaj ob txoj kab rov tav flanges (sab saum toj thiab hauv qab) thiab lub vev xaib ntsug txuas cov flanges. Cov flanges muab kev tiv thaiv tiv thaiv kev khoov thiab shear rog, thaum lub vev xaib txuas lawv thiab muab kev ruaj ntseg ntxiv.
