Recessed Drain Cover

Large Opening for Easy Maintenance Access

 

Large drainage pipes under city roads require regular inspection and maintenance. Workers need sufficient space to access underground chambers with maintenance tools and equipment, so the opening size is an important factor.

Our product has a diameter of 900 millimeters, making it a large-size option for drainage access applications. It is suitable for main city drainage pits, commercial complex pipelines, and large inspection chambers.

The wide opening allows maintenance workers to enter and operate more efficiently, improving the overall efficiency of underground pipeline maintenance.

Recessed Design for Seamless Road Integration

 

This recessed drain cover features a recessed paving area on the surface. The recessed section allows tiles or stones to be installed inside the cover.

After installation, the cover matches the surrounding road surface and creates a clean, integrated appearance. This design provides a practical solution for large access openings while maintaining the visual quality of urban roads.

It is especially suitable for city main roads, landscape projects, and areas that require both functional performance and aesthetic design.

This large recessed drain cover provides reliable load-bearing performance. We use high-quality ductile iron material and a reinforced frame structure to improve overall strength.

The thicker frame helps prevent settlement and deformation under vehicle loads. The wide flange design increases contact with the road surface, distributing pressure more evenly and reducing the risk of cracking around the pit.

During long-term use, the frame remains stable with the surrounding pavement, while the paving layer stays securely positioned.

We have extensive experience in manufacturing large ductile iron products. Our melting equipment handles large volumes of molten iron, and our sand casting workshop is equipped with large molding machines for stable Φ900 production.

Large castings require precise control of key production factors, including iron temperature, pouring speed, and cooling rate. Our technicians have rich experience in managing these processes.

Each product is manufactured with a dense internal structure and undergoes strict quality inspection to help minimize casting defects.

We support customized sizes according to customer requirements. Regular orders are shipped within 15 to 25 days. We use steel pallets for export packaging.
