简述了冷轧带肋钢筋的生产工艺及性能。4种不同管径的砼排水管按等强度设计原则，以冷轧带助钢筋替代原用的冷拔低碳钢丝后，可节省钢材10％～31％，并提高砼排水管的裂缝荷载，破坏荷载等质量指标和安全度。
The production process and properties of cold-rolled ribbed bar are briefly described. According to the principle of equal strength design, the four kinds of concrete drainage pipes with different diameters can save 10% ~ 31% of the steel by replacing the original cold-drawn low-carbon steel wire with the help of cold-rolled steel to help increase the crack load of the concrete drainage pipe, Destruction load and other quality indicators and safety.
