Urban infrastructure relies on materials that can withstand constant pressure, environmental exposure, and long-term use without compromise. Ductile iron manhole covers are an essential part of this system, offering secure, durable access to underground utilities such as drainage.

Telecom, and electrical networks. Jingang LuoKaiwei is a recognized manufacturer and supplier of ductile iron covers and gratings, delivering products that meet international standards while offering flexibility through OEM customization.

Engineered for Strength, Safety, and Longevity

Ductile iron is known for its excellent mechanical properties, making it the preferred material for manhole covers in both light-duty and heavy-duty applications. Unlike traditional cast iron, ductile iron contains spherical graphite structures that give it superior tensile strength, impact resistance, and flexibility.

These characteristics are especially important in high-traffic areas, where covers must resist constant vehicular loads, environmental changes, and wear over time. Jingang LuoKaiwei ensures that every ductile iron manhole cover is engineered to perform under pressure.

Products are designed with different load-bearing capacities according to client specifications, whether for residential streets, industrial zones, or major roadways. With a focus on safety, all covers are tested for slip resistance and stability, helping reduce the risk of accidents in public spaces.

Tailored Designs with OEM Support for Specialized Projects

Customization is a key advantage offered by Jingang LuoKaiwei. The company provides full OEM services, allowing customers to request specific sizes, surface patterns, logos, or even hinge mechanisms as needed. This makes it easy to integrate the covers into a variety of urban and industrial environments without compromising design or function.

Clients can choose from a wide range of cover types, including solid top, perforated, recessed, or locking covers, depending on the purpose and location.

Matching ductile iron gratings are also available, offering comprehensive solutions for water drainage and utility access. Every product is manufactured using strict quality control processes, ensuring consistency, strength, and reliability in every shipment.
