Q355 Q235 Steel H Beam

Q355 Q235 Steel H Beam

Q235 steel yog carbon structural steel. Nws yog sib npaug rau A3 thiab C3 hlau hauv cov qauv qub GB700-79 qib, uas yog qib ntawm Lavxias TOCT. Q nyob rau hauv tus lej steel stands rau yield zog. Raws li ib txwm muaj, cov hlau siv ncaj qha yam tsis muaj kev kho cua sov.Q355B cov khoom yog cov khoom siv qis-alloy high-strength structural steel, qhov "Q" txhais tau tias muaj zog yield, 355 txhais tau hais tias lub zog tawm los ntawm cov hlau no yog 355MPa, thiab nws cov nqi tawm los. yuav txo qis thaum lub thickness ntawm cov khoom nce.
