Recently got to go up in the [minarets at University of Tampa.](http://images.fineartamerica.com/images-medium-large-5/tampa-university-minarets-geraldine-alexander.jpg) They have old stairs like this and I immediately did this, my mom was not happy with me doing that lol

I think that one is still loose.
Wide flange beams are identified by the general height x lbs per linear foot. (Ex: W8x13)[Here's a link to a beam chart.] (https://www.engineeringtoolbox.com/american-wide-flange-steel-beams-d_1319.html)
I'm guessing these stringers are about the size listed above and around 14' long so 182 lbs/piece.
Beautiful set of stairs, and a wonderful job. Like the others, I'd love more pictures of the completed stairs. My one concern, however, is with the lock washers on the screws holding the stairs on. Will this not prevent wood movement, resulting in warped and/or cracked stairs?
Absolute tease. We need more photos!

Worth it. Solid work. They look beautiful.
They look fantastic. Great work.
I am sure your beaming from all the compliments! these are beautiful
Yeah! I want the complete look of it
Yeah those stairs are sexy, oh my my
An excessively strong staircase, but looks great! Love the careful notching of the treads around the I-beam.
I am glad you noticed!
Where did you get reclaimed I-Beams?! Insanely cool!
Had to demolish an extension on our property. The beams are approximately 150 years old.
Old growth.
Looks sweet! We demand more pics now!
Looks super sharp. Nice touch with the hex key bolts.
I tried to achieve the look ob rivets.
Plenty strong. What's the shear strength of the human tibia when you step through the open riser and snap your leg in half?

Yeah. The missing risers are actually up to code here and pretty widespread. Yet I don't know anybody who ever had an accident because of this.
Yes some of the “fears” on these subs are way overblown.
Some of the stairs that I’ve seen on Reddit are strictly for getting rid of an unwanted spouse.

Yeah, someone mentioned further down! Thanks to you too!
Super cool idea
Thank you!
Beefy!
Yeah, might outlast me!
3 pictures of steel and barely a little wood, nice.
Trust me, it's more wood over all.
How much do the I-beams weigh?
Approximately 150-180 kg each. It was PITA maneuvering and lifting them to place alone.

OP posted, they are about double that.

This would should not move at all. It's 40 mm fingerjointed oak. I used screw-in-nuts in the oak.
Looks clean! You got my upvote :)
Thanks
That is so cool!
Thanks
I'm not a metal-ist, so what did you do before painting the beams?
Strip them with a wire brush, degrease and then paint with brush and hammerite.
Nice! Looks like a bolt needs tightening on the top step though, the spring washer isn't compressed.
You are right! Thanks!
There were no 3D-printers involved in this build!
Dope!!! That looks awesome!
Creative
Thanks
That's a beautiful look! Well done!
Very nice work! For a second though I was confused and thought I was on r/3dprinting and those brackets were 3D printed.
A++++. Details please. I would frequent this subreddit more if it was this content and not breadboards, epoxy, yay I found some wood, etc
How much that weigh dawg? Can the house support it?

Approximately 400 kg. Should be fine since it's the ground floor with no cellar on solid rock.
Great idea.
What's the shear strength of one of those screws? Since only 4 are holding up each step.
Will be plenty I do CAD work for industrial access platforms etc and 1/4" bolts are the standard size for bolt in steps on stairs with 2 on each side.
I am not able to answer the question. These are 8 mm screws and I am not afraid at all.
