GB QU Crane Rails
Crane rails are the core load-bearing components of industrial lifting equipment, which directly affect the smoothness, safety and service life of the crane.
Crane rails are special rails used to support and guide the wheels of cranes (such as bridge cranes, gantry cranes, cantilever cranes, etc.). They are usually made of high-strength steel and have the characteristics of wear resistance, impact resistance,high load strength ,high stability and high load-bearing.
According to the material classification, it can be divided into carbon manganese rails (U71Mn), which are economical and practical and suitable for ordinary working conditions. Alloy rails (U75V), with higher strength, are used for heavy-duty or high-speed cranes. Stainless steel rails , corrosion-resistant, suitable for food and chemical industries.
Among them, the use of U71Mn has the highest cost-effectiveness. Alloy steel costs more but has a longer life, wear resistance and impact resistance, and a long life. The life of U71Mn rails is 50% higher than that of ordinary Q235 rails, reducing the frequency of replacement.
The use of hot rolling forming technology makes the crane more efficient and suitable for mass production.

overhead crane rail Applications
Crane rails are widely used in industries such as industry, logistics, ports, and construction. For example, in the field of industrial manufacturing, the automobile manufacturing industry uses production line bridge crane rails, construction sites use tower crane running rails, and so on. Crane rails also play an important role in some special fields.
Steel rail Packaging & Delivery
In product packaging and transportation, GNEE implements rust prevention treatment for rails using plastic film, anti-rust paper, and application of rust-proof paint. Simultaneously, to prevent rail deformation during transit, we provide additional protection for rail ends.
GNEE STEEL is a company engaged in international trade of high-quality steel products, committed to providing high-quality steel solutions to customers around the world. As an industry leader, we have rich export experience and a wide international customer network, and our products are exported to many countries and regions around the world. From construction steel to industrial manufacturing steel, we provide a variety of product options and strictly follow international quality standards and environmental protection requirements.
