A mesh grating may be manufactured to the load class required at your manufacturing facility but if you use small wheeled trolleys, which create small point loads, it may not be fit for purpose.

Small trolley wheels apply high small point loads to gratings which may exceed their load class and destroy the grating. As a result, in this type of application, ACO recommends the specification of slot and not mesh gratings.

For more information about ACO’s range of slot gratings or to get detailed specification guidance regarding gratings, load classes and any aspect of your drainage system design, please contact the ACO technical design team who will be happy to provide advice and guidance for your individual project requirements.
