EN S355JR 762X2X2XX197 \/ 220 Universal Steel System (H BAR)
Cov khoom siv cov yam ntxwv ntawm S355jr h Hom Beam
S355jR H Profile Steel yog European Standard en10025 Tsawg Alloy Txheej Txheem Ntau dua lossis sib npaug rau cov qauv ntsuas kub ntawm qhov chaw kub.
Chemical composition of S355JR h profile steel: C Less than or equal to 0.24%, Mn Less than or equal to 1.60%, S\/P Less than or equal to 0.025%, carbon equivalent (CET) Less than or equal to 0.45, ensuring welding performance.
Kev ua kev ua tau zoo ntawm s355jr h ntaus hlau nqaj: Txhawb kev txias txias, txiav thiab ntau yam vuam thiab cov pa hluav taws xob vuam). Tom qab ua, tshav kub yuav tsum tau tswj kom txo qis kev pheej hmoo ntawm embrittlement.
S355jr steel nqaj zaub mov txawv: painmental kub dov (+ n) lub xeev, ib txwm kho tau kho dua tshiab lossis sib npaug ntawm 6 qib) thiab txhim kho qis qhov kub.
Universal Beam txheem seem tshwj xeeb
UB 762 × 267 × 197 Qauv Hlau University
Qhov loj me: Tag nrho qhov siab 762 hli, Flange dav 267mm, Web tuab txog 12.5mm, Flange tuab txog 23.6mm.
Theoretical qhov hnyav: 197kg \/ m, ntu modulus (elastic modulus) ntau dua lossis sib npaug rau nruab nrab loadarios (xws li cog trusses).
UB 762 × 267 × 220 Universal nqaj txheem hlau
Qhov loj me: Tag nrho qhov siab 762 hli, Flange dav 267mm, Web tuab txog 14.2mm, Flange tuab txog 26.8mm.
Ntau lub zog: 220kg \/ m, tshooj modulus rau 5000cm³ ntau dua li 5000cm³, haum rau cov qauv siab (xws li choj ci).
Universal nqaj qauv hlau kub siv cov txheej txheem
Gnee Adopts Rolling Txuj Ci Qauv, thiab cov dov qhov kub ntawm ntu thiab qhov ntev ntev, uas tuaj yeem tiv taus kev ua kom ntev ± 31, tag nrho qhov siab zam ± 5 hli).
Cov khoom lag luam saum npoo uas peb muab tuaj yeem yog kub-dip flozing ntau dua lossis sib npaug rau 85μm) lossis tshuaj tsuag anti-corrosion los txhim kho huab cua tiv thaiv huab cua.
