The dimension indicated here is likely 50 50 cm with a thickness of 6 mm. Aluminium alloys such as 5052, 6063, or LM6 (cast aluminium) are commonly used for such manhole covers due to their lightweight, corrosion resistance, and durability.

500 x 500 x 60mm Aluminium Recessed Manhole Cover: key details

This 500 x 500mm recessed manhole cover is made from aluminium alloy with a 60mm deep tray, so you can fill it with patio slabs, tiles or screed and make the cover blend into the floor around it. Aluminium is light to lift, does not rust and will not stain the paving around it.

Where to use it

It suits patios, paths, gardens and indoor floors. For driveways and areas with vehicle traffic choose a cover tested to EN124 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 patio slabs, tiles 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 60mm recessed tray?
The 60mm tray suits patio slabs, tiles or screed. Allow for the bedding layer under the infill so it finishes flush with the frame.

Is an aluminium cover strong enough for a patio?
Yes, for pedestrian use. Aluminium also keeps the tray light enough to lift without special tools.
