What is this holed sheet or mesh?

[jim]

The mesh I'm thinking of is the grey zinc plated type of flat sheet which is covered in diagonal rows of holes, each maybe around 1/8in/3mm dia, punched in it.

You used to see it used over things like larder windows where a reasonable barrier against bugs, but also ventilation, was needed.

Extruded mesh will not do, as my application needs a flat sheet without bumps and a lower proportion of hole space than you find with normal mesh.

I need a piece min size around 250mm x 400mm but larger ideally. Could maybe join 2 smaller pieces if no other way.

Anyone know what this mesh is called?

Any suggestions as to possible sources please?

TIA

1/8in/3mm

The stuff on larders was perforated zinc sheet ( ie not galvanised steel) however perforated galvanised sheet sheel is available from these people but is not cheap:

needed several 8' x 4' sheets to make a sound deadening louvre assembly last year for my generator and found an advertiser on ebay selling offcuts in Milford Haven who cut my bits to size and shipped them across the country for less than half the price of buying from the stockholder who is local to me!

I don't think it would be easily obtainable in such sizes but if it doesn't have to be metal, what about veroboard?

perforated zinc sheet.

Not other than Cambridge (Mackays), no.

Solid soft zinc, not plated. You'll still find it (small sheets and not cheap) around places dealing with fibreglass. Otherwise try non-ferrous metal stockists, including the specialists in meshes. I think even Relics in Witney carried it, after some housepr0n show made a pie-safe with it.

Some electronics enclosures use steel or aluminium perforated in the same fashion for electrical screening/ ventilation.

I seem to remember that, at least, in American English, it is called "cane metal" but googling gives lots of results for magician's props!

Just a thought... dunno if you need zinc or whether ali or steel would be OK.

The message from "jim" contains these words:

Perforated sheet - as opposed to expanded metal mesh.

It was I think solid perforated zinc sheet, rather than plated. The modern replacement is probably a woven plastic mesh (if the intention is to keep insects out), which is used for that purpose on caravan windows- a caravan repair specialist would be able to supply the plastic mesh.

Have you tried B&Q? They have various metal sheets/meshes/grilles in small quantitities in the larger branches.

=========================== I agree with the general consensus that it's called 'perforated zinc (sheet)' and the last time I bought some I got it from a local Builders' |Merchant where it was then (several years ago) a stock item. Worth trying your local BM.
