Production Description
Our Locking Ductile Iron Manhole Covers are designed with integrated locking mechanisms to ensure secure access and enhanced safety in public and high-traffic areas. Manufactured from EN-GJS500-7 ductile iron, these covers offer excellent impact resistance and long-term durability under heavy loads.
The locking systems include bolt locks, stainless steel twist locks, and anti-theft mechanisms tailored to client needs. These features prevent unauthorized access and are ideal for applications in power, telecom, and city infrastructure networks. Sealing gaskets can also be added to improve odor control and water tightness.
