Cold-rolled ribbed steel structure design points: The minimum reinforcement ratio selection. Due to the design value of the tensile strength of steel CRB550 level is 1.71 times the HPB235 grade steel, when the reinforced concrete structure using CRB550 CRB550 grade cold rolled steel rebar prices can be reduced by a minimum configuration of steel reinforcement ratio. Thus greatly reducing the total amount of reinforcing steel and steel consumption. Seismic housing height should be higher than the current maximum applicable national standard "design of concrete structures." Cold-rolled ribbed steel production equipment: cold-rolled ribbed steel production equipment based on the number of rolls in two and three-roll-shaped roll shape. Three-roll mill rolls active and passive arrangement wholesale CRB550 same cold-rolled steel, by its production line consisting of no traction machine, it is cold-rolled steel by electric motor, reducer direct drive shaft CRB550 cold-rolled steel concluded Quote, roller shaft torque rolls and gave it a reliable connection, steel, driven by advances in national education movement of the roll, and by reducing rolling ribs. CRB550 cold rolled rebar _ _ cold-rolled steel cold-Ding Ding provided by Ding Ding Industrial Co., Ltd., Henan Province. Ding Ding Industrial Co., Ltd., Henan Province (www.hnddsy.com) is Anyang, other leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
