Source for perforated alloy sheet in 3mm thick?

[hotponyshoes]

I am looking for a supplier of 2.5mm or 3mm thick aluminium sheet perforated.

I have the remains of a sheet here so i know it's available but all my seaches result in 3mm holes but the thickness is only going up to 1.5mm

The stuff I have is 12mm holes on a 31mm pitch but the hole sizes/spacing are not really an issue. It's the thicker sheet I am after.

All pointers welcome!
Thanks

Just had another look at the piece I have..
It's 3mm thick but only 240mm wide and looks like it may have been custom cut.

The holes have been punched out.

Does anybody know what this is?

We used to have 3mm aluminium stair treads made up with punched holes.
I think if it was available, we'd've bought it by the sheet, rather than custom punched.

Having said that, you might find that having a company punch it for you might not work out any more expensive than plain .
