Annular corrugated steel pipes (CSP) feature a unique circular corrugation pattern that provides exceptional strength and flexibility, making them ideal for culverts, storm sewers, and drainage systems. Their durable design ensures long-term performance with minimal maintenance, while their easy installation helps reduce labor costs and installation time.
The annular corrugation enhances the pipes’ load-bearing capacity, making them suitable for projects requiring high structural integrity. Their design also allows for flexibility in adapting to various terrains and installation conditions, ensuring reliable performance in diverse environments.
Our Annular corrugated steel pipes products are made from high-quality galvanized steel, offering a balance of strength and corrosion resistance. For projects in harsh conditions, we provide additional protective coatings, such as asphalt (bitumen) or epoxy resin, to enhance durability and corrosion protection.
