Currogated Iron Arch Flooring

Does anyone know where I can get the corrugated Iron needed to replicate a corrugated iron arch floor system? It doesnt need to be iron i can use steel.

To duplicate that style, I'd cut the appropriate dia culvert pipe into two halves with a Sawzall or equal. Could burn them, but that would require lots of extra hours of manual grinding to get the bottom (cut edge) even enough to carry the load equally. And even then you'd only be approximately straight on both sides of both halves.

Doubt you'd be able to purchase the halve-sections fabricated into halves already.

Thanks for the advise, but culvert pipe is spiraled and these ceilings are not, the other difference is that it is not a half cylinder it is a low arch. Anyone else ever have this fabricated?

I have seen this sourced in NY/NJ area as it is used to repair NYC Schools built in 1920-1930's that used this system. I was told it is available from most suppliers as it is used for temporary construction dams and such. Is there a specific reason you have to use the original product/modern copy (IE: Arch material is visible/not covered by ceiling?)
It is available at Menard's, Lowes and Home Depot is variety of widths in 8 and 10 ft lengths with 2 1/2" width of trough

Thank you for the help. We are in San Antonio, Tx and this process was not used much. We are restoring an 1880's court house in South Texas, and the corrugated metal used in the floor construction will be visible in the rooms below. What is there is in good shape but we are reconstructing clock tower that was removed in the 1920's to give the building a modern look, and the floors/ceilings in that are will be completely new.

corrugated metal plate is not generally spiral. Spiral rib pipe is, but you don't want that. you can construct using corrugated multi-plate without cutting pipes in half. You might even be able to specify plate size and bending geometry. that is the same technology used for quonsets.

What I have seen here in NYC in Schools and Municipal buildings of the age is they used corrugated metal panels spanning from beam to beam at web/bottom flange angle in an arch. Filled on top with Cinder concrete. We do not even attempt to repair in kind, we rip it out and do standard reinforced concrete slab using LW Concrete (115-120 psi). See attached photos of typical failure in a building dating from 1910. Feel free to contact me if I can be of advice.

Corrugated steel pipe manufacturers (culverts) make oval and round sections, partial circumferences, etc. and they are not spiral, the ribs are parallel. Check them out, you should have no trouble matching what you need.
