Fixings for Gratings

Fixings for Gratings

Gratings should be anchored to the supporting structure. This can be done in various ways. Here are some of the alternatives recommended by Weland. Grating fixings are available as both complete and separate components. Clips are available for ensuring load transfer between gratings.

The components are also available in hot dip galvanised and stainless steel versions.
