500 x 500 x 50mm Stainless Steel Recessed Manhole Cover: key details

This 500 x 500mm recessed manhole cover is made from 304 stainless steel with a 50mm deep tray, so you can fill it with tiles, thin paving or screed and make the cover blend into the floor around it. 304 stainless steel resists rust and staining, so it suits wet areas, gardens and coastal properties.

Where to use it

The manufacturer rates this cover at 5 tonnes. It suits patios, paths, gardens and indoor floors. It does not carry an EN124 B125 rating, so for driveways and areas with vehicle traffic choose a cover tested to B125 or above.

How to fit a recessed manhole cover

1. Check the cover and frame size against your chamber opening before you start.
2. Bed the frame on a full bed of mortar so its top edge sits flush with the finished surface, and check it is level in both directions.
3. Lift the tray out and fill it with tiles, thin paving or screed, bedded on mortar or screed so the infill sits flush with the frame.
4. Grout or point the joints to match the surrounding surface, keeping the lifting points clear.
5. Let the mortar cure fully before the cover is walked on.

Frequently asked questions

What size manhole cover do I need?
Measure the opening of your inspection chamber and compare it with the 500 x 500mm size above. The frame needs a solid bed of mortar all round, so check there is room for it on the chamber walls.

Can I drive over this manhole cover?
It is not rated to EN124 B125, which is what most driveways need. Use a B125-rated cover or higher wherever vehicles will cross it.

What can I put in a 50mm recessed tray?
The 50mm tray suits tiles, thin paving or screed. Allow for the bedding layer under the infill so it finishes flush with the frame.

Will a stainless steel cover rust?
Grade 304 stainless steel is highly resistant to rust in normal outdoor and indoor conditions. Wipe off cement and grout residue after fitting to keep the frame clean.
