RCC vs CI: what’s the difference?

RCC (reinforced cement concrete) covers are precast and widely used for chamber access and drainage systems. CI (cast iron) covers are metal and are often selected for specific municipal standards or high-load locations.

Practical comparison

• RCC precast: strong, corrosion-resistant, cost-effective for many chamber applications.
• Cast iron: high strength-to-size, commonly used in some municipal road specs.

Which one should you choose?

Choose based on your site specification (load class), theft risk, installation method, and total cost of ownership. For many housing, township and industrial premises, RCC precast covers with a proper frame are a reliable choice.

Tip: match the size correctly

Whether RCC or CI, sizing mistakes cause rocking, gaps, and uneven seating. Read our guide on frame size vs clear opening before placing an order.
