Products Description
China's standard rails can be divided into light, heavy and crane rails.
Heavy steel rails are widely used in national trunk railways and high-speed railway lines. QU70 is a heavy rail. These models have greater bending strength and wear resistance and can withstand the continuous impact and load of high-speed trains.
Heavy steel rails are used in special environments such as high cold, high heat and high humidity. Some projects also need to choose low-temperature steel or weather-resistant rails to enhance their environmental adaptability.
Steel rails for railroad are usually designed in an I-shape, which not only gives the rails good bending strength, but also effectively disperses the vertical load and impact force generated by the train.
