Metal Floor Deck 2

[I-beam]

Hi
Does anyone know what type of metal deck that is in the attached photo. The flutes are 6"oc and 2" deep, the slab is 5.5" thick
and spans 8ft. Slab has #4s @ 6" at mid-depth. I found a similar deck on-line manufactured in the UK, and it is a composite deck,
and shows headed studs welded to the sheet between the flutes. In the attached photo you can see a dimple in the bottom of the deck
that may be indicative of a welded stud location.
I am hoping to find the manufacturer and load tables for this deck. This deck was cut from a building in New England.
Thanks so much

Some sort of dovetail deck. Looks to be pretty heavy gauge actually - 16ga? What sort of framing system is in the building? I would say it could be some sort of infinity systems EPICORE MSR deck, but the dovetails look a little too wide, and gauge is a little heavy. The deck doesnt appear to be composite (at least not like any composite deck i'm used to). Composite deck typically has deformations along the flutes to grab the concrete. Headed studs would typically only be installed on top of a composite beam - welded from the top down. You'd see a big gnarly weld, and a beam attached to the deck... Whats that bolt sticking out of the top? Used to keep the chunk of floor from falling out of the bottom?
I'm guessing this big chunk was supposed to be removed? Because the floor is now missing a decent amount of rebar. But this could be at a lap splice.

The available heaviest deck thickness is only up to 16 gage, but the Vulcraft load table might be useful. Link Looks like it has no problem to span 8'.

This deck was used in a retrofit in old textile mill in Maine to replace the wood decking in a few bays. The supporting wood girders were sistered with C12s, so it was likely for supporting a fairly heavy piece of equipment. I found the attached deck info on the web - from the UK.
So my question remains, which US deck manufacturer would have supplied this...

It looks like it may be New Millenium's Versa-Dek (

https://www.newmill.com/long-span-composite/versa-dek-composite-system.html)

Attached is the design/load tables document from their website. They have a 2" deep, 16 gauge option which seems to match your dimensions (page 20 has the properties).

NJ92 - you nailed it - thank you, exactly what I was trying to find. The deck does have a nice appearance.
It actually looked liked the underside of the wood decking it replaced with the narrow joints.
Thanks all for valuable feed back.

Nice catch, NJ92!

Glad I could help and thanks for the stars guys. I guess my first post on this site was a success.

A few of my colleagues have had projects recently that used the Versa-dek so when I saw the non-standard deck profile in the picture, it immediately came to mind. The long span/deep deck options like the Versa-dek or Bailey's Comslab have actually come up quite a few times recently as an alternative to precast planks.
