Classification | Geometric shape | Classification or classification based on the cross-sectional shape of the transverse ribs and the spacing between the ribs. For example, in the British standard (BS4449), rebar is divided into type I and type II. |
Performance classification (grade) | For example, in my country's current implementation standard, rebar is (GB1499.2-2007) and wire is (1499.1-2008). |
