Our Manufacturing Process
Raw Material Selection & Testing
We source high-quality cement, aggregates, steel strands, and additives. All materials undergo rigorous testing in our in-house laboratory to ensure they meet specified standards.
Concrete Batching & Mixing
Computer-controlled batching plants ensure precise proportioning of materials. The concrete mix is prepared with optimal water-cement ratio for maximum strength and durability.
Mould Preparation & Pre-stressing
Steel moulds are cleaned and prepared. High-tensile steel wires are tensioned to specified levels before concrete placement to create pre-stressed sleepers.
Concrete Placement & Compaction
Precision concrete placement followed by thorough vibration ensures complete compaction and elimination of voids, resulting in dense, homogeneous sleepers.
Curing & De-tensioning
Controlled steam curing accelerates strength development. After achieving required strength, pre-stressing strands are carefully released to transfer stress to the concrete.
Quality Testing & Dispatch
Each sleeper undergoes rigorous testing for dimensions, strength, and performance. Certified sleepers are then stored properly before dispatch to project sites.
