RCC (Reinforced Cement Concrete) Pipes and Covers are strong, durable, and widely used in infrastructure projects for stormwater drainage, culverts, sewage systems, and irrigation. Made by reinforcing concrete with steel bars, they offer excellent load-bearing capacity and long service life. RCC pipes come in various classes (NP2, NP3, NP4) depending on the pressure requirements and are suitable for underground installations. Covers, often used for manholes and inspection chambers, are designed to withstand heavy traffic and environmental conditions. RCC products are corrosion-resistant, cost-effective, and ideal for both municipal and industrial utility networks, ensuring reliability and structural integrity in harsh conditions.
