Metal in the cold rolling process, due to "work hardening" twisted metal lattice atom in an unbalanced position 10.5mm cold-rolled strip steel straight purchase, the metal structure is in an unstable state. However, at low temperature, insufficient activity of the metal atoms, can not transition to a steady state. When the temperature rises straight cold-rolled strip steel 10.5mm wholesale, eliminating the elastic lattice distortion, improved cold-rolled metal, plastic 10.5mm straight rebar prices, reducing the metal's hardness and strength, then it will Reply phenomenon exists. Design features rolled ribbed steel structure: tensile (compressive) strength selection. According to "cold-rolled ribbed steel Technical specification for concrete structures" in the reinforced concrete structure, for the general configuration, CRB550 grade steel tensile, compressive strength design value of 360N / mm; for axial tension and small eccentric tension member design value of tensile strength cold-rolled ribbed steel bars greater than 300N / ram2, should 300N / tom2 adoption. 10.5mm cold rolled straight rebar spot, Ding Ding cold rolled, cold-rolled straight rebar Gansu 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. In cold-Ding Ding leadership with the staff warmly welcome all inquiries negotiations to create a better future for cold-Ding Ding.
