Looks like nice work. Was there an issue?

[Joseph Hagarty, CMI]

Not that I could see.... Somewhat over design
You could park a car on this structure.

[Jeffrey R. Pope]

I used to build structures like that on a much larger scale. If properly constructed, you could park several vehicles on it.

The welds in photo 2 are not broken? All kinds of cement porch's, patios and Olympic Stadiums . HA HA HA. in Montreal.
The land of ice locked streets and waterways.
It is a design flaw and the wrong use of material to stop rust.
What part of the states?
Those H beams could carry a building. Little overkill if you ask me.
Looks OK but for that style home home. 1950's and beams with corrugation.
I will take photos and post them when its a bit warmer.

[Joseph Hagarty, CMI]

Expense for this type construction exceeds the housing area.
...this structure as it stands is 10 years old

Porch does span across to the adjoining property...
A Privacy Wall was added by a Subsequent Owner.

[Joseph Hagarty, CMI]

Did not notice any cracking at the welds.
Problems with paint adhesion and some areas of corrosion,,, not sure how it was painted.... did not detect any issues to warrant a recommendation to X-ray the welds

Handrails do look like stadium rails...

[ROBERT V. YOUNG]

Doubt you would need xray Mr.Hagarty. That cement slab is not a heavy mass for the beam-work.
For any residential area that is not typical building practice.
It can sometimes be challenged by municipality if someone complains.
It is comerical applocation in a residential building zone.
Mostly cement columns and form slab in Montreal Mr.Hagarty.
I will take some photos of friends homes. Nicely finished when the integrate steel into the architecture.
Much small circumferences of iron work and beams.
I have some shots taken in Greese of my friend exterior wrap around balcony being built. I was impressed. I will get 200 plus photos. All cement rod and no precast. It old school work that I grewup on. Bloody nice.

I’ve seen or heard it many times on this and other message boards; building to code should be the minimum standard, not the ceiling (or words to that effect). Well it looks like someone has done just that, they have far exceeded the bare minimum.

Cool, looks to be very low maintenance.

[Marcel R. Cyr]

Wow! Unusual to see something like this in a residential world.
This thing could support 3 floors with no problem.

Looking at the connections, it is obvious to me that this material was left over from a commercial project somewhere and adapted to this design. Those welded connections are going nowhere.

Most assemblies as such would have been fabricated by a steel fabrication company and would have had bolted connections on the columns. This one shows field applied clip angles and the standard perimeter C-channels to support the 3" composite decking for the slab above.

This is an overkill for the use. Those H-columns would have the capacity of much more loading then in the picture.

Composite deck is also a component that becomes part of the suspended slab and becomes one with the other. Capable of 5-7' spans between beams.

The 3" Composite floor decking is the deepest and most structurally sound concrete flooring panels available. The deep profile allows a deep and stronger pour of concrete therefore a higher slab depth can be had. As with all the floor decking panels the widths allow for easy installation with the male and female receptors. Deck to be welded to all supports at 8” on center. Available in 16, 18 or 20 gauge. Typical stock lengths are 8, 10 and 12′ length, but can custom produce up to 20′ length.



Good find Joe. Very interesting to see that in the residential arena.

No issues Here?

I've installed Robinson decking with unsupported spans of 20+ feet. This is good stuff.

[Marcel R. Cyr]

Robinson decking, not familiar with that Jeff.
Spans to 20' can't be for concrete roof/slab support.
Composite decking for concrete is usually for spans to 7' between beams and the beams are cambered or beam sag of up to an 1" is expected if not and compensation of levelness is required.
Must be a roof deck material you are talking about.
Here is a picture of roof deck profiles on the left and floor deck profiles on the right;



Do you have info on that product you are talking about?

[Bob Elliott]

Ha ha
Soon as I looked my thought was there were no major structural issues and wondered why he was asking us to look.
Thought something about the conduit.
