Product Description
Our Locking Ductile Iron Manhole Covers are engineered for enhanced safety, theft prevention, and secure sealing. Manufactured from high-grade EN-GJS-500-7 ductile iron, these covers comply with international EN124 load standards, making them suitable for urban roads, telecom facilities, and utility infrastructure.
Each cover is equipped with a robust locking mechanism—available in bolt, spring, or automatic configurations—providing tamper resistance and ensuring that the cover remains securely in place under heavy traffic or in restricted-access zones. The integrated neoprene gasket ensures a watertight and odor-proof seal, making it ideal for sewer and water management systems.
Our advanced sand casting process guarantees precise dimensions and high load performance. The covers can be customized in size, logo, surface pattern, and coating to meet specific regional or project requirements.
