Cold-rolled ribbed steel (commonly known as cold rolled rebar) in recent years developed a new, highly efficient, energy-saving construction materials, which in ordinary low-carbon or low-alloy rod rod, multi-channel cold-rolled or cold Reducing and pull together the indentation, the final form of reinforced with two or three sides of the crescent-shaped transverse surface ribs. Because of its high strength steel wire rod 9mm, plastic 9mm rod rebar spot, strong bond (bond with concrete anchor capacity increased 2-6 fold) 9mm steel wire rod plant, which developed rapidly. Refers to the reinforcement of concrete reinforced and prestressed concrete steel wire rod 9mm steel shelf, its circular cross section, sometimes a square with rounded corners. Including plain bars, ribbed bars, torsion bars. Reinforced concrete with reinforced concrete refers to straight bars or reinforced with strips of steel plate, its shape into round bar and deformed bar two, the delivery status for round two straight bar and plate. 9mm steel rod manufacturers, 9mm rod steel, cold-rolled by Ding Ding Ding Ding Industrial Co., Ltd., Henan Province.
