Q355 qib yog cov khoom siv hlau tshiab uas hloov Q345 qib hauv cov qauv tshiab GB / T1591. Cov qib steel muaj plaub ntu Q (thawj lub cim "Q" ntawm lub zog tawm los hauv Suav spelling), 355 (qhov tsawg kawg nkaus tensile zog tus nqi hauv MPa), tus me nyuam mob (AR, N, M) thiab steel zoo (B, C, D, E, F). Lub AR raws li dov mob feem ntau raug tshem tawm zoo li Q355B.Vim qhov kev xa khoom sib txawv, muaj cov tshuaj sib txawv thiab cov khoom siv kho tshuab rau Q355 steel. Hauv qab no yog cov lus qhia ntawm kub dov Q355 steel phaj. Q355B steel yog sib npaug rau Q345B thiab S355JR steel.
