Import Ductile Iron Cast Round Manhole Cover — Buy in Bulk from Supplier in China

The product is a ductile iron cast round manhole cover produced by Changsha Jinlong Foundry Industry Co., Ltd. in China. It is offered in six load classes - A15, B125, C250, D400, E600 and F900 - each corresponding to the EN124 classification for road and pedestrian traffic. The covers comply with EN124 standards and carry a BSI LRQA certification under ISO 9001:2008, confirming the foundry’s quality management system. A corrosion‑resistant finish is applied to the cast iron to extend service life in outdoor environments.

Ductile iron provides higher tensile strength and ductility than traditional gray iron, allowing the covers to sustain heavy static and dynamic loads while resisting cracking. The material’s nodular graphite structure is typical for Class 400 and above, delivering impact resistance suited to urban infrastructure. The standard surface coating, usually a zinc or epoxy layer, reduces rust formation and aligns with municipal maintenance requirements. Typical dimensions for a round cover range from 400 mm to 800 mm in diameter, with a thickness of 30 mm to 70 mm depending on class.

These covers are commonly installed by municipal road authorities, parking‑lot developers and utility firms that need reliable access points for drainage and service lines. Changsha Jinlong Foundry lists flexible minimum order quantities and supports both CIF and FOB shipping terms, allowing buyers to choose the most suitable logistics arrangement. Prospective importers should verify the exact class, diameter and coating type required for their project before placing an order.

Changsha Jinlong Foundry Industry Co., Ltd. is located at No.260, Jinchang Road, Jinjing Town, Changsha 314000, Hunan Province, China.
