Ductile Iron Manhole Cover Heavy‑Duty Round Square EN124 for Municipal Road Sewer Drainage

Our high-performance ductile iron manhole cover is professionally manufactured with premium nodular cast iron raw materials. Compared with traditional gray iron covers, our products feature higher toughness, stronger pressure resistance, better ductility and zero breakage under heavy pressure. Strictly produced in accordance with EN124 international standard, this series of manhole covers is widely recognized and adopted by overseas municipal engineering, road construction, drainage system, water supply system, fire protection system, parking lot, residential community, industrial zone and gas station projects.
We supply full specifications of ductile iron manhole covers, including round, square and rectangular types with complete matching frames. A variety of load classes are fully available, including A15, B125, C250, D400, E600 and F900, which can perfectly adapt to pedestrian walkways, residential light traffic roads, urban main roads, highway heavy-duty lanes, logistics vehicle passages and super heavy-load industrial areas. All sizes, inner openings, outer diameters and thickness can be customized according to customer drawings and project technical requirements.
The surface of the manhole cover adopts high-quality bitumen anti-corrosion painting treatment, which effectively isolates air, rainwater and ultraviolet radiation. The product has excellent anti-rust, anti-corrosion, wear-resistant and weather-resistant performance, ensuring long service life in outdoor harsh environments all year round. The surface is designed with clear anti-slip patterns to prevent slipping accidents for pedestrians and vehicles, greatly improving construction safety and road traffic safety.
Anti-theft hinge structure, locking device and anti-loosening design are optional, which can effectively prevent manhole cover loss, displacement and noise caused by vehicle rolling. The overall structure is precise, the fitting gap between cover and frame is uniform, no jumping, no shaking, no loud noise during use, which meets high-standard municipal road construction requirements.
We support full OEM and ODM customization services, including custom size, thickness, surface pattern, embossed logo, project name, brand mark and special technical parameters. We can produce products that fully conform to local national standards and project specifications in different countries.
All products will undergo strict raw material inspection, hardness testing, pressure testing, appearance inspection and dimension checking before delivery. Defective products are strictly prohibited from being shipped.
