Reinforced by the production process points: hot-rolled, cold-rolled, cold-drawn steel 9mm cold rolled steel straight there to Ⅳ grade heat-treated steel made of heat-treated cold-rolled steel 9mm straight rebar spot, more strength than the former high. According to the role in the structure of the points: compression reinforcement, tensile reinforcement, erect steel, distribution of steel bars, stirrups and so on. How much money are many kinds of steel rebar 9mm cold rolled straight, usually by the production process according to the role in the structure of the use of sub-classification. Primary steel, structural engineering mixed straight rebar plant, such as band type foundation, structural columns, ring beam, such as roof or floor slab with a level larger than 9mm cold rolled steel; civilian or cast frame structure industrial buildings, bridges and other structures and water conservation with two, three more steel. Three steel than the level of steel in order to save the next segment is not the case, the general reinforcement plates are constructed, which has the smallest ratio of reinforcement to control the minimum reinforcement ratio is directly related to steel grades. 9mm cold rolled straight rebar prices | 9mm cold rolled straight rebar | cold-Ding Ding Ding Ding Industrial Co., Ltd., Henan Province by.
