Manufacturing Process
All processes with their materials are chosen for manufacturing LRPC steel strands to ensure high tensile strength and very low relaxation properties:
1. Selection of Raw Material: High-carbon steel wires are the base material.
2. Wire Drawing: From a few drawing dies, steel rods are drawn into fine wires of specific diameters.
3. Stranding Process: Cross twisting of drawn wires into a certain design forms the strand.
4. Heat Treatment: The strand is subject to heating that is controlled to allow for mechanical property enhancement and reduction of relaxation.
5. Surface Coating: Coatings may be either zinc or epoxy coatings for protection from corrosion.
6. Quality Testing: The completed strands undergo comprehensive testing against tensile strength, relaxation property, and durability.
7. Packaging and Distribution: The final product is wound onto reels and packed for delivery to construction sites or export markets.
List of Machinery Required
1. Wire Drawing Machine – Converts steel rods into thin wires.
2. Stranding Machine – Twists multiple wires together to form the strand.
3. Heat Treatment Furnace – Improves tensile strength and reduces relaxation.
4. Coating Machine – Applies protective coatings for corrosion resistance.
5. Tensile Testing Machine – Ensures compliance with quality standards.
6. Cutting and Winding Machine – Prepares strands for packaging and distribution.
7. Automated Packing Machine – Ensures efficient and secure packaging.
Investment and Financial Viability
- Initial Investment: Setting up an LRPC steel strand manufacturing unit requires an investment of ₹5-10 Crores depending on the scale of production.
- Profitability: Return on Investment (ROI) can be expected within 3-5 years with increasing demand and high-profit margins.
- Break-even Point: From 2-3 years onward with efficient production and selling and marketing strategies, break-even is usually achievable.
- Government Incentives: Moreover, MSME schemes, tax benefits, and subsidies could further lower the costs of capital and increase profitability.
