Product Introduction

QU70 GB hot-rolled crane rail is a steel material commonly used for crane track laying.

Rail height 120mm
Bottom width 120mm
Head width 70mm
Waist thickness 28mm

Usually made of U71Mn material, this material has high strength, hardness and good toughness, and can withstand various loads during the operation of the crane. The tensile strength of the QU70 rail made of U71Mn material is greater than or equal to 880N/mm², with good strength and fatigue resistance, which can meet the requirements of long-term operation of the crane.

Hot rolling is an important process for producing QU70 national standard crane rails. During the hot rolling process, the metal undergoes dynamic recrystallization at high temperature, which refines the grains inside the steel, thereby improving the comprehensive mechanical properties of the steel, such as strength, toughness and plasticity. For QU70 rails, this means that it can better withstand various loads during the operation of the crane, including static and dynamic loads, reduce the possibility of track deformation and wear, and extend the service life of the rails.

GNEE RAIL is a professional foreign trade company with outstanding performance in the field of international trade. It has long been committed to providing high-quality steel products and solutions to global customers. ​

QU70 GB hot-rolled crane rail is our core product. Its rail height is 120mm, bottom width is 120mm, head width is 70mm, and waist thickness is 28mm. This unique cross-sectional size design gives the rail excellent stability and load-bearing capacity. The material is U71Mn, which is a high-quality carbon structural steel containing manganese. While ensuring good toughness, it greatly improves the strength and wear resistance of the rail. According to authoritative testing, the tensile strength of the rail fully meets or even exceeds the national standard requirements. It can stably carry a weight of 50-100 tons under various complex working conditions. It is widely used in large-scale engineering construction, port terminal container lifting, and gantry crane operation inside industrial plants. It provides a solid guarantee for the efficient and safe operation of cranes.
