Grating Panel Edge

Grating Panel Edge

Grating Panel Edge

(OP)
Hi!

I have been said that it is a good practice to keep 10mm gap between edge of grating and edge of steel. What is the reason for that?

Please note, I do not mean edge between adgacent grting panels.
Thank you for your answers in advance!

RE: Grating Panel Edge

Steel grating is a fabricated product, it has manufacturing tolerances on size. The gap is to make sure the grating will fit even if it is slightly larger (but within allowable manufacturing tolerance) than the nominal size.

Also, the supporting structure has construction tolerances that could result in a smaller gap than expected.

As time goes by, grating often has to be removed for various reasons. The gap makes sure that the grating does not get wedged into place by normal small movement of the supporting structure.
