Many different types of cold-rolled steel 8mm straight rebar plant, usually by chemical composition, production process, rolling shape, supply form, diameter, as well as use in the structure classification. Divided by the diameter steel wire (diameter 3 ~ 5mm), fine steel (diameter 6 ~ 10mm), crude steel (diameter greater than 22mm). Divided by the mechanical properties of steel grade Ⅰ (300/420 level); Ⅱ grade steel (335/455 level); Ⅲ grade steel (400/540) and Ⅳ grade steel (500/630). In the construction industry, the level Ⅱ Ⅲ grade steel and reinforced in the past (the old standard) is called, the new standard in Class Ⅱ renamed HRB335 grade steel reinforcement, Ⅲ grade steel renamed HRB400 steel. Both reinforced the same point is: all belong to ordinary low-alloy hot-rolled steel; all belong ribbed steel (which is usually said rebar); can be used in reinforced concrete structural engineering.
