✅ Export-Ready Operations: Documentation, packaging, and logistics optimized for international shipping


State-of-the-Art Production Capabilities

Multi-Product Lines: Dedicated facilities for UPVC, CPVC, and PVC-O pipes and fittings

Advanced Extrusion Technology: High-precision twin-screw extruders ensuring consistent wall thickness and dimensional accuracy 

Automated Injection Molding: Precision-engineered fittings manufactured to ASTM, DIN, and ISO standards 

Scalable Capacity: Flexible production scheduling accommodating both bulk orders and customized projects

Vertical Integration Advantage

Unlike trading companies, we control every critical touchpoint—from raw material compounding to final quality inspection. This ensures traceability, cost efficiency, and rapid response to your project timelines.


Technical Leadership: Three Core Product Technologies

1. UPVC Systems — The Reliable Standard

Applications: Cold water supply, drainage, irrigation, and industrial fluid transport

Standards Compliance: Manufactured to IS 4985, ASTM D1785, and ISO 4422 specifications 

Key Benefits: Corrosion-resistant, lightweight, and 100+ year service life expectancy

2. CPVC Systems — High-Performance Thermal Solutions

Superior Heat Resistance: Operating temperatures up to 200°F (93°C) 

Chemical Resilience: Resistant to acids, bases, salts, and oxidants—ideal for chemical processing and hot water distribution 

International Certifications: ASTM F441/F442 compliant, NSF/ANSI 61 approved for potable water 

3. PVC-O (Oriented PVC) — The Future of Pressure Piping

Our PVC-O technology represents the cutting edge of pipeline innovation:

Molecular Orientation Process: Advanced air-based orientation technology that realigns polymer molecules, increasing tensile strength and impact resistance by up to 50% 

Unmatched Efficiency: Up to 50% thinner wall thickness than conventional PVC-U for the same pressure class, resulting in higher flow capacity and lower transportation costs 

Superior Mechanical Properties:

Exceptional fatigue resistance

No crack propagation

100% recyclability with maintained structural integrity 

Global Demand: Increasingly replacing metal and polyolefin pipes in water infrastructure projects worldwide
