Designed for Frequent Opening
Stormwater drainage systems usually require more maintenance than regular inspection points. Frequent opening and closing can challenge the fitting accuracy, durability, and stability of drainage covers.
Our Ductile Iron Access Covers provide a practical solution for these requirements. They are designed for easy access while maintaining a secure fit after repeated operation.
We offer four load grades for this product: light, standard, heavy, and extra heavy. All grades can achieve a 400 kN load capacity. This allows customers to choose the right option according to actual road traffic conditions. Different areas of the same project can use different grades, helping reduce unnecessary costs and improve budget control.
Round Design for Better Load Distribution
Our factory has produced stormwater drainage products for many years. Changxing Jianguo Ductile Iron Manhole Cover Factory was established in 2002. We have supplied products for drainage projects in many major cities.
For stormwater applications, we optimize our material composition by adding suitable alloy elements. This improves corrosion resistance and helps the Ductile Iron Access Covers maintain strength in wet and mildly acidic environments.
We inspect every production batch before shipment. We also perform load testing on sample covers to verify product performance. These quality checks ensure that every product meets the 400 kN load requirement.

Fast Delivery and Flexible Orders
We keep regular products in stock to support faster delivery. Standard orders can be shipped within 6 to 15 days after confirmation. We use steel pallet packaging to provide better protection during long-distance sea transportation.
We accept mixed orders, allowing customers to combine different load grades in one container. This makes it easier to meet the requirements of different road sections within the same project.
We provide a 1 to 3 year warranty for all products to support long-term project reliability. Our Ductile Iron Access Covers are a dependable choice for stormwater drainage systems, municipal projects, and urban infrastructure applications.
