Ob tug tub ntxhais EN cov qauv tswj I-beams txuam GB/T 706 (GB kub- dov kuv- kab teeb txheem):
TS EN 10025-2: 2004: Cov khoom xav tau rau cov qauv hlau (S355JR rau Q355B, S235JR rau Q235B), qhia txog lub zog, toughness, thiab chemistry.
TS EN 10279: 2000: Dimensional tolerances and shape specs for hot-rolled I-beams (IPE/IPN profiles), mirroring GB/T 706's depth (± 1.5 mm for 200–300 mm) and flange width (± 1.0 mm for 100–200 mm) tolerances.
Ua ke, cov qauv no ua kom cov European I-beams ua tau raws li GB cov khoom thiab cov kev xav tau loj, ua kom muaj kev sib txuam tsis sib haum rau hauv Suav tsim.
