• About

Manholes are accessible through frames and covers while catch basin frames and grates receive surface water runoff. Both castings take the weight of traffic passing over the manhole or catch basin structure. Out of necessity, frames, covers and grates must withstand massive highway loads on bearing surfaces. Each cover should have deep ribbing and raised letters to lessen wear and prevent skidding.

When it comes to castings, true or not, many customers feel confident that 'heavier is better.' We stock a full line of 'heavy' manhole frames and covers and catch basin grates and frames.

We also stock an alternative product that many customers find inviting – the ductile iron frame and cover. Lighter than cast iron, ductile iron has better bearing capabilities at comparable prices and is much easier to handle and install.
