EN 10025-2 specification S355J2 channel steel and S275JR channel bar
Source:Xin Steel Industry Date:2021/08/23
S355J2 channel steel and S275JR channel bar both come from european standard EN 10025-2 specification and non-alloy steel materials.S355J2 channel steel has a higher tensile strength than S275JR channel steel,and also S355J2 channel steel have to be done low temperature impact test at -20 degree centigrade,so S355J2 channel steel can bear minus 20 Deg.c cold weather,however S275JR channel steel can not.
EN 10204 3.1 mill certificate along with stock S355J2 channel steels and S275JR channel bar,such as U channel steel with tapered flanges UPN 100×50×6×8.5,UPN 120×55×7×9,UPN 200×75×8.5×11.5;UPE Channel steel with parallel flanges UPE 80×50×4×7,UPE 120×60×5×8,UPE 140×65×5×9,UPE 220×85×6.5×12.
