Flat bulk grill.
 
So I have been renting out PA equipment for the past 6 months and it has been very profitable. Expecially since I just do it in my free time.

Now, I have eight 18" reflex bins and for the longest time I have been using these standard round, driver grill covers.

I'm looking to get covers that cover the entire front of the box, like this.

Does anyone know of something such as, sheets of grill, in bluk. Something like that.

Metal shops would have it. Check around for pricing as price varies according to what type you get.

I already know about those.

The version I would need is very pricey.

The cheap way to do it is to use wire mesh on a frame with filter foam in front of it. Not as nice to look at though. Perforated steel is pretty expensive from what I've seen of it.

I buy mine at metal shops, but I also look at a few of the surplus/scrap metal dealers in town. The punched steel (all the little holes) looks best IMO, but can get expensive, the expanded steel grate also looks pretty good (the diamond shape cutouts) and you can get it in all different thicknesses and hole size, most places will cut it for you on a shear. Once painted/powdercoated, they all look good. I like buying it this way because I build the speaker, then take exact measurements (taking into consideration the thickness of carpet or Line-X) to the shop and have the exact size grill cut...

Looks like my best bet is just to go with those sheets from PE.

I got a quote from two metal shops. 8 sheets cut to size would be $300+!

While 8 sheets from PE would be around $160.

Yikes! I would also go with P/E...

home depot sells expanded metal sheets. I know other hardware type stores do too.

Also there's www.onlinemetals.com for perforated.

a quick look over there shows 12x12" sheets with various hole patterns for $9-22 each in aluminum. a bit more for stainless, a bit less for plain steel.

And www.mcmaster.com ...

I still really like the expended grate. This one was for 3 12s and I welded a trim piece around it and had it powdercoated. I fugured you may go the same way with stand-offs since your boxes are already complete, usually I would build them to flush mount if I intended a grill like this from the start...
