Frequently asked questions

What is the difference between a gully grating and a manhole cover?

A gully grating admits surface water through open slots. A manhole cover normally closes an access chamber and is selected primarily for access and load performance.

What information is needed for drainage capacity?

Provide the catch basin opening, expected flow, available grate area, slot direction and any debris or pedestrian safety requirements.

Can the grate be fixed against theft?

Bolted, hinged or captive arrangements may be available depending on the frame and maintenance method.

Which load class should be used?

The engineer should select the class from the installation area and project standard. Road traffic and kerb locations can require different classes.
