Alumalite vs ACM

[brycesteiner]

Is 6mm ACM the same rigidity as 6mm Alumalite? I'm working on a sign quote and the ACM is less expensive. I know it's a little heavier in weight.

What would you use?

Its not always the case, the fluted in some respects is stronger than the solid core.

Alumalite is more rigid, but you have to deal with the edges. For some signs it doesn't matter, but for nicer projects it may make a difference. Alumalite is also more prone to dings. We use more ACM but still use alumalite too.

Who wants to lug a solid core 4 x 8 around ?? Not me.

I believe the corrugated is stronger, but more so, it's not the strength in these two products from the core, but the thickness of the aluminum sheeting being used for facing. That's usually why there's a price difference. Something like .013 vs. .007.

Geez Gino...I'm sure you remember the days of 4x8 3/4 MDO. Now that was something to lug around . I worked at a shop where we would buy truckloads of it and the storage area was thru a regular size door, around a corner and then up on the racks...

I personally detested working with Alumalite, sharp edges, hard to cut, edges don't look finished, dents easily plus I
printed directly to panels and Alumalite was bad about having bent edges & corners, that could ruin my print heads if not spotted.

As Dylan used to sing....

Ah, but I was so much older then

I'm younger than that now.

Something like that........................... ​

Thanks for the info! This was helpful. I am quoting it for ACM just to get my feel with it. I use quite a bit of 6mm Alumalite but it's so easy to get a dented edge or corner on the sheet. I don't think that ruins it, but I hate to start off with something I'm already not happy with.

I've use alumalyte indoors with full panel graphics that bleed to the edges. The decal folds over and covers the open core edges. We do hanging store signage like this all the time. This only works for stuff that's going up out of harm's way and won't be jerked with later.

I've also made a sandwich of two 10mm alumalyte panels with two back-to-back 1/2" aluminum angles, bond the whole thing together with VHB. The aluminum angle finishes the edge and gives it a slimline edge finish.

it depends on where the sign is going and what structure you have behind it. if its a 2- 4x4 post yard job then go with alumalite for rigidity. if its going against a wall or you have a full frame then 3mm ACM is fine.
