Cold-rolled ribbed steel has been widely used in building construction, in particular has been widely used in the construction of real estate on the ground, floor, roof, etc. Cold-rolled ribbed steel has been widely used in ordinary reinforced concrete floor, floor, roof, etc., while the beams, columns and shear stirrups also been a certain application Buy 9mm cold-rolled steel wire rod, its tensile, compressive strength of the design value can reach 360N / mm2, compared with 9mm HPB235 grade cold-rolled steel wire rod rebar prices, tensile, compressive strength design value improves 150N / ram2, is the strength of 1.71 times. Cold-rolled ribbed steel structure design points: fatigue stress amplitude limit. Steel plate for class members under fatigue loads 9mm cold-rolled steel wire rod, when the maximum stress fatigue checking does not exceed 300N / ram2, fatigue stress ratio is not greater than 0.3, the fatigue stress amplitude should not be reinforced greater than 120N / ram2. Concrete strength selection. For reinforced concrete structures in a class environment, the concrete strength grade of not less than C20. Cold-rolled steel wire rod mill 9mm, 9mm cold-rolled steel wire rod, cold rolled by Ding Ding Ding Ding Industrial Co., Ltd., Henan Province. Ding Ding Industrial Co., Ltd., Henan Province (www.hnddsy.com) strong, credible, and other industries in other Anyang accumulated a large number of loyal customers.
