Product Details

Cold rolled ribbed steel bar is a new model practical construction steel material. It is widely used as the fitting bar for various steel bar concrete structure engineering and making of various construction components. With its high strength and the fixing strength with concrete, its sufficient plastic property, it can enhance the technical and the quality of the engineering, reduce the cost of raw materials and the cost of engineering at the same time. The finished products can be round coil or straight sizes.


It is not only increase the yield performance and tensile strength, but also reduces the steel use, project cost, consumption of coal and water, waste water and dust emissions, save resources protection, more importantly, slow down the greenhouse effect by releasing less smog pollution
