GNEE RAIL Provides High-Quality GB Standard Steel Rails

 

 

GB Steel Rail refers to steel rails manufactured according to Chinese National Standards (Guobiao - GB), commonly used for high-speed railways, national trunk lines, mining, and crane applications. These rails, complying with standards like GB/T 2585-2021, are known for strict chemical controls, high-strength manganese-alloyed steel (e.g., U71Mn), and specialized wear resistance.

 

GNEE RAIL maintains a comprehensive inventory across the three primary GB classifications: Light Rail, Heavy Rail, and QU Crane Rail.Our production facility adheres to strict metallurgical controls to meet the specific requirements of GB/T 11264, GB/T 2585, and YB/T 5055.

 

 

GB standard steel rails are classified primarily by weight (light, heavy, or crane), application, and material composition, adhering to Chinese national standards (GB 2585-2007) for railway and industrial use. Common classifications include 38kg/m–75kg/m for heavy rails and QU70–QU120 for crane rails. They are typically manufactured from high-quality carbon or alloy steels, such as U71Mn or 50Mn.

 

1. GB Light Rail (GB/T 11264)

 

Designed primarily for forest areas, mining sites, and factory logistics lines, light rails prioritize ease of installation and cost-efficiency for lower-speed applications.

 

• Common Profiles: 6kg, 9kg, 12kg, 15kg, 22kg, 24kg, 30kg.

 

• Materials: Typically Q235B or 55Q.

 

• Primary Use: Underground mining tracks, temporary construction lines, and light industrial transport.

 

 

Classification		Height(mm)	Head (mm)	Bottom (mm)	Thick(mm)	Weight (kg/m)
Light Rail	8 KG/M	65	25	54	7	8.42
	9 KG/M	63.5	32.1	63.5	5.9	8.94
	12 KG/M	69.85	38.1	69.85	7.54	12.2
	15 KG/M	79.37	42.86	79.37	8.33	15.2
	18 KG/M	80	40	80	10	18.06
	22 KG/M	93.66	50.8	93.66	10.72	22.3
	24 KG/M	107	51	90	10.9	24.46
	30 KG/M	107.95	60.33	107.95	12.3	30.1

 

2. GB Heavy Rail (GB/T 2585)

 

Heavy rails are the backbone of national transit, engineered to withstand the high-frequency impact of passenger and freight traffic.

 

• Common Profiles: 38kg, 43kg, 50kg, 60kg, 75kg.

 

• Materials: U71Mn, U75V.

 

• Primary Use: National trunk lines, high-speed railways, and urban metro systems.

 

 

Classification		Height(mm)	Head (mm)	Bottom (mm)	Thick(mm)	Weight (kg/m)
Heavy Rail	38 KG/M	134	68	114	13	38.733
	43 KG/M	140	70	114	14.5	44.653
	45 KG/M	145	67	126	14.5	45.546
	50 KG/M	152	70	132	15.5	51.514
	60 KG/M	176	73	150	16.5	60.64

 

3. GB QU Crane Rail (YB/T 5055)

 

Unlike standard transport rails, QU Crane Rails feature a wider head and thicker web to support the vertical and lateral loads of heavy machinery.

 

• Common Profiles: QU70, QU80, QU100, QU120.

 

• Materials: U71Mn,U75v.

 

• Primary Use: Gantry cranes in ports, overhead warehouse cranes, and heavy-duty workshop lifting systems.

 

 

Classification			SIZE(mm)							theoretical weight
			height	bottom width		head width		waist depth
Crane rail		QU70	120	120		70		28		52.8
		QU80	130	130		80		32		63.69
		QU100	150	150		100		38		88.96
		QU120	170	170		120		44		118.1

GNEE RAIL emphasizes transparency in the production process. Every batch undergoes rigorous testing to verify compliance with GB standards:

Ultrasonic Flaw Detection: Ensuring internal structural homogeneity and the absence of micro-cracks.

 

• Dimensional Accuracy: Maintaining strict tolerances for rail height, head width, and web thickness.

 

• Mechanical Testing: Assessing tensile strength, elongation, and impact toughness to guarantee longevity under high-frequency loading.

 

 

Our facilities are ISO 9001 certified, and we provide full Material Test Reports (MTR) with every shipment, ensuring that procurement teams have the documented proof of quality required for international tenders.

 

FAQ

 

1. What are the key differences between GB Light, Heavy, and Crane rails?

Light rails (6kg-30kg) are optimized for light loads and mining; Heavy rails (38kg-75kg) are built for high-speed and freight transit; Crane rails (QU series) feature a reinforced profile with a wider head specifically to handle the concentrated wheel loads of heavy lifting machinery.

 

2. Which material grade is recommended for heavy-duty freight lines?

For heavy-haul or high-traffic lines, we recommend U71Mn or U75V. These grades offer superior wear resistance and fatigue strength compared to standard carbon steels, significantly extending the service life of the track.

 

3. How do you ensure the quality of GB standard rails during production?

We implement a multi-stage quality control protocol, including chemical composition analysis, ultrasonic flaw detection to identify internal defects, and rigorous dimensional checks to ensure every rail meets the exact tolerances specified in GB/T 2585 or YB/T 5055.

 

4. Can GB steel rails be customized for specific project lengths?

Yes. While standard lengths are 12.5m and 25m, we provide precision cutting and drilling services to meet specific site layouts, reducing the need for complex on-site modifications and welding.

 

5. Are your rails compatible with international fastening systems?

While designed to GB standards, these rails can be integrated with various fastening systems. We provide a complete range of matching rail clips, fishplates, and rubber pads specifically engineered to fit GB profiles, ensuring a secure and stable rail assembly.

 

6. What measures are taken to prevent corrosion during international shipping?

To protect rails during maritime transit, we apply specialized anti-rust coatings and utilize bundling techniques that minimize surface abrasion. This ensures that the rails arrive at your destination in installation-ready condition, even in high-humidity environments.
