The clip should be tight enough to prevent sliding of the grating.
Every piece of grating restrained at each corner by hold-down clips?
Every piece of grating should be restrained by at least two hold-down clips at each intermediate support.
No grating clip is used to hold two adjacent panels together.
Saddle clips should be used in place of standard (i.e. “Grate Fast”) clips on grating edges that are *supported by channels with flanges* extended outwards.
Is grating free from heavy corrosion or rust?
If grating is fastened with welds instead of clips, are all welds secure and located on each corner and two per each intermediate support, as a minimum?
