Corten Steel Panels

I'm building several cinder block walls for a water feature. The walls will be faced with corten panels and water will pour from a spillway on the top and cascade down the face.

What is the best method for attaching 1/4" corten steel panels to the cinder block walls? Sizes vary between 2'x4' - 3'x7'. I'd like to avoid seeing any attachment hardware from the front. Is it possible to use construction adhesive, mortar, thin-set?

Holly cow! 1/4" thick panels. That sounds like something I would build.

By Corten I assume you are talking about steel sheeting that doesn't get painted or protected and you just let it rust.

I would not trust any adhesive in that environment with sheets that heavy. I would mechanically fasten them. Easiest would be to drill holes in the plates and bolt them. Maybe for a decorative affect you could use stainless or brass bolts. If you don't want to see any hardware I'd weld something on the back like threaded rod, bolts or rebar that you could mortar or use epoxy adhesive into holes drilled into your CMU block wall.

Thanks for the info! This actually raises another question, is 1/4" sheet too thick / overkill for my application? Should I consider thinner? This is meant only to be decorative facing on the front of cinder block walls. Dimensions are:

3'x3'
3'x4'
4'x5'
2'x4'
3'x7'
2'x6'

I think you could just use the light gauge corten panels, like the ones they use for roofing or equal. Those things last 30 years or more, so longevity is not an issue, and you don't need mechanical strength since it's just decorative. Plus they will be way easier to attach securely.

The roofing panels usually have raised edges for waterproof seaming....you don't need those, but they have thin, flat panels as well.

Yes, 1/4" is too thick unless you want the thickness of the edges to be visible or unless you want to hide behind it if someone starts shooting. If you go with something like 14ga or thinner then gluing becomes an option. I'm not sure how adhesives from your local home center would work but there are many industrial adhesives that would work. You can surf the industrial side of the Loctite website for structural adhesives to get an idea of what's available.

Here's a rendering of the overall design. The ledge stone along the sides of each piece of corten will be thicker than anything.

Interesting project Lot of water to move.

You have six material dimensions yet only four piers shown. Will there be six of them ?

Sorry, am also doing a firepit using 2 pieces of corten as well.

If I use 1/8" steel for this project, will there be any problem welding pins to the back without causing visible blemish or changes to the front?

Also, if I change the design of the fire feature as follows, is 1/8" corten steel thick enough to remain upright and rigid in this example?

1/8" steel is roughly #11 gauge steel.

Welding pins to the metal will show on the face.

In the second picture it looks like you are using it free standing (not attached). If that is correct I wouldn't think 1/8" is heavy enough.

In the 2nd picture half the sheet would be attached to the wall, the other would hang over and be free standing. I'm trying to get a sense of how rigid that half would be at 1/8", or if I would need to install some kind of support behind it as well.

Hmmmmm.... no way to weld 1/8" without causing trouble on the front huh? That kind of limits the best attachment method recommended here.

I had thought that the panels came with a finish. Apparently they don't.


Corten flat sheets do not arrive pre-rusted. Weathering steel will rust naturally when exposed to the weather
That would mean you should be able to weld on studs and then sand the panel. You'd probably need access to a spot welder. Not sure if a torch could be used without causing the metal to distort.

Stud welding should be able to attach "pins" to the back without warping the front. You'll get some heat staining but it shouldn't warp the metal. Stud welding is similar to spot welding so the application of heat is very brief and localized. If you don't like the heat stains a light buffing or sanding would remove it.
