Products Description
43kg heavy rails are a kind of high-strength and high-load-bearing railway tracks, which are widely used in many fields such as heavy-load railways, high-speed railways, and long-distance passenger railways. It has strong wear resistance, corrosion resistance and stability, and can meet the transportation needs in complex environments. Although its weight and cost are high, 43kg rails are an ideal choice in railway systems that require high strength and high load.
Adaptable environment
Heavy-load railway environment:
43kg rails are suitable for high-load railway systems, such as transportation lines for heavy goods such as minerals and steel.
High-speed train environment:
In some high-speed railway systems, 43kg rails can withstand the strong dynamic pressure during the operation of high-speed trains and ensure the stability of the track system.
Frequent use environment:
Suitable for lines with frequent train operation, which can reduce the wear and deformation of the track and provide long-term stability.

Other Features
Application fields
U71Mn rails are widely used in high-speed railways, heavy-load railways and urban rail transit, including:
1.High-speed railways: as the core support structure of train operation, ensuring driving safety and stability.
2.Heavy-load railways: withstand frequent rolling of heavy-load trains, reduce track deformation and wear.
3.Urban rail transit: adapt to the high-density operation needs of subways, light rails, etc., and reduce maintenance costs.

About Us
1. What is the hardness range of the rails?
Answer: The hardness of conventional rails is 260-300HB, and the hardness of wear-resistant rails can reach more than 350HB (such as UIC60E).
2. Are there any after-sales quality claim clauses?
Answer: If non-human quality problems are found within 30 days after arrival, replacement or compensation can be negotiated based on the test report.
3. Can the markings on the rails be customized?
Answer: Laser engraving of factory logos, specifications, production batches and other information is supported (extra cost is about $X/ton).
4. What are the specifications of the rails?
A: We supply a variety of specifications, such as 30kg/m, 50kg/m, 60kg/m (for ordinary railways), and 75kg/m, 80kg/m (for heavy-load railways). The length is usually 12.5m, 25m or customized length.
5. What is the minimum order quantity (MOQ)?
A: The MOQ is usually 1 20-foot container (about 20-25 tons), which is adjusted according to the specifications. Small batch trial orders are supported.
