GNEE RAIL as a professional foreign trade supplier of steel rails, we have long been deeply engaged in the GB rail market, dedicated to providing global customers with high-quality, traceable rail products. GB/T 14330 Hot-rolled Steel Rails for Railway Use is China's most authoritative rail specification standard. Our regular products cover 50 kg/m, 60 kg/m heavy rails,light rail,qu crane rail,rail fasteners and special turnout rails, with cross-sectional dimension deviations strictly controlled within ±0.5 mm, and straightness and curvature meeting or exceeding GB standards.

In terms of chemical composition, we use high-quality raw materials, with carbon content precisely controlled at 0.68–0.72%, silicon at 0.17–0.37%, manganese at 0.50–0.80%, and sulfur and phosphorus contents below 0.035%. This ensures the rails exhibit excellent toughness and wear resistance under high-stress, high-impact environments. All products pass ultrasonic flaw detection, magnetic particle inspection, and tests for tensile strength and impact energy absorption (impact energy ≥20 J, tensile strength ≥880 MPa) conducted by third-party authoritative institutions, providing customers with reliable quality assurance reports.

For different operating environments, we can offer customized solutions such as hot-rolled prestressed rails and high-wear-resistant alloy steel rails based on project requirements. We also support multiple logistics methods including rust-proof packaging, crane loading, container transportation, and bulk shipping to optimize trade costs. Leveraging mature supply chain management and foreign trade experience, we can quickly respond to orders, deliver accurately, and provide one-stop services from sample testing, delivery transportation to on-site technical support.

We understand that different countries and railway lines have varying standards and certification requirements for rails. Thus, we actively assist customers in aligning with product certifications (e.g., EN, DIN, ISO) and provide necessary inspection and test documents. Choosing our GB rails means not only selecting cost-effective infrastructure materials but also partnering with a professional, stable supplier to jointly ensure the safe and efficient operation of global railway projects.If you have any customization requirements, please contact us.
