In the construction industry, 10mm cold-rolled strip steel straight purchase, grade Ⅱ Ⅲ grade steel and reinforced in the past (the old standard) is called, the new standard in Class Ⅱ renamed HRB335 grade steel cold-rolled steel 10mm straight rebar plant, 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. Different levels of cold-rolled steel straight bars, because of the different chemical composition of cold-rolled steel 10mm straight how much rebar, different chemical composition, its also caused by different mechanical index. One, two, three steel producing country in accordance with the needs of society to work out the material standards, its yield strength, ultimate strength, elongation, cold, and weldability are very different, the use of different levels of reinforcement Location also great together. 10mm cold-rolled steel plant straight, straight cold-rolled steel, cold rolled by Ding Ding Ding Ding Industrial Co., Ltd., Henan Province.
