- Thermal resistance
Superior Strength and DurabilityDesigned to meet stringent Indian Railways Standards, these prestressed concrete sleepers boast a compressive strength of over 50 MPa and a density range of 24002550 kg/m. Their robust composition guarantees high load-bearing capacity and prolonged service life, making them ideal for heavy main line and branch railway usage.
Advanced Manufacturing ProcessUtilizing centrifugal moulding and pre-tensioned prestressing technology, every sleeper is formed with high-precision steel moulds, resulting in uniformity and excellent dimensional stability. The 7-wire strand reinforcement (9.5 mm diameter) enables superior tensile strength and corrosion resistance, ensuring reliability across diverse climates.
Maintenance-Free PerformanceWith a smooth, flat, non-porous surface and water absorption of less than 3%, these sleepers remain unaffected by environmental factors. Their fire-resistant and corrosion-resistant properties mean less frequent checks and negligible maintenance costs over the entire service life of the railway track.
FAQs of Prestressed Concrete Sleepers:
Q: How are prestressed concrete sleepers manufactured?
A: Prestressed concrete sleepers are produced using centrifugal moulding and pre-tensioned prestressing technology. High-strength concrete is poured into precision steel moulds and reinforced with 7-wire strands of 9.5 mm diameter, ensuring optimal durability and uniformity.
Q: What standards do these sleepers adhere to for railway applications?
A: These sleepers strictly conform to Indian Railways Standards IRS:T-39, meeting all requirements for compressive strength, dimensional accuracy, load capacity, and longevity, making them suitable for main line and branch track installations.
Q: When should railway operators choose prestressed concrete sleepers over alternative materials?
A: Prestressed concrete sleepers are recommended for locations requiring high load-bearing capacity, corrosion resistance, fire safety, and minimal maintenance, particularly in tracks exposed to harsh environmental conditions and heavy axle loads.
Q: Where can these sleepers be installed and what is the recommended quantity per kilometer?
A: Applicable for main lines and branch tracks across India, these sleepers are installed at a rate of approximately 1660 to 1700 per kilometer, ensuring proper load distribution and track stability.
Q: What are the primary benefits of using prestressed concrete sleepers for railway infrastructure?
A: Benefits include long service life, fire and corrosion resistance, high load capacity (up to 25 tonnes axle load), low water absorption, and virtually maintenance-free operation, contributing to reduced lifecycle costs for railway operators.
Q: How does the sleepers surface finish impact its performance and longevity?
A: A smooth, flat, and non-porous surface finish, achieved through precision moulding, prevents water penetration and reduces wear, enhancing both durability and resistance to environmental factors.
