GB Heavy Rail
GB Heavy Rail Manufacturer
GB heavy rail refers to high-strength, wear-resistant steel rails complying with GB/T 2585-2007, designed for heavy-haul freight (e.g., 75 kg/m rails) and high-speed railways (e.g., 60 kg/m rails), constructed with grades like U71Mn to ensure durability under extreme loads and speeds, while supporting seamless integration into China’s national rail network and international projects.
Key Features & Specifications
Weight Classes: Available in 38 kg/m, 43 kg/m, 50 kg/m, 60 kg/m, and 75 kg/m variants, each tailored to specific load requirements.
Dimensions: Heights range from 134 mm (38 kg/m) to 192 mm (75 kg/m), with base widths of 114–150 mm and head widths of 68–75 mm.
Material Grades
U71Mn: Manganese-alloyed steel (0.65–0.76% carbon) offering ≥880 MPa tensile strgth.
50Mn: Carbon-manganese steel (0.48–0.56% carbon) for balanced strength and ductility.
Certifications & Compliance
Meets GB/T 2585-2007 and aligns with international standards (e.g., UIC, EN) for global export.
ISO 9001 and CE certifications available upon request.
Customization Options
Length Flexibility: Rails cut to project-specific lengths (6–24 meters).
Coatings: Zinc-nickel plating or polymer coatings for corrosion protection in coastal or humid environments .
Rail accessories: rail clips, fish plates, rubber pads, steel plates, etc.
Global Applications
