Cold-rolled ribbed steel bars are ordinary low-carbon steel, high-quality carbon steel or alloy steel hot rods bottom of the base material for cold-rolled steel wire rod, cold rolled after cold rolling reducing its surface to have three sides or crescent-shaped transverse ribs on both sides of steel. In recent years, as the Ministry of Construction of new steel grades to promote the application, with high strength and fatigue resistance, to reduce project costs Buying 7.5mm cold-rolled steel wire rod, save the limited resources 7.5mm cold-rolled steel wire rod steel spot, improve market competitiveness and so on. 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 7.5mm cold-rolled steel wire rod prices for general configuration, CRB550 grade steel tensile, compressive strength design value of 360N / mm; for axes Heart and small eccentric tension cold-rolled ribbed steel tension members is greater than the tensile strength of the design 300N / ram2, should 300N / tom2 adoption. 7.5mm cold-rolled steel wire rod mill | cold-rolled steel wire rod | cold-Ding Ding Ding Ding Industrial Co., Ltd., Henan Province by. 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.
