What is the best way to fabricate Steel Stringers for my deck?
 
I'm building a steel deck and have yet to figure out how I'm going to do the stairs. I want to build them out of steel and dont have the budget to have a fabricator build them for me. I guess all I really need is help with is the stringers. The material I'm using it to cover the risers is 3" thick combined and I can only have the last 1/2" show. So I know I need to allow for that in keeping with the 7 3/4" drop code, while keeping and lip aesthetically pleasing.

I guess I could get some large 14 or 16 gauge track(10" or 12") and cut it out of that, but I can not find how to do that while allowing for the riser material.

if you cant afford to have it done right and dont know how to... just do it in wood

I understand what youre saying, but that answer could be given to almost every inquiry on here; but then we wouldnt have a forum.

BTW, I can't do it in wood.

do you have any photos of the deck?

Can you post pics and/or draw something for us? I am confused! which is normal.

what im stating is that if you dont know how to build stairs dont try to out of material you dont know how to use.. it will cost you more money and time then anticipated. stairs arent a beginner project even with wood

We're just starting the framing on Monday or Tuesday. We needed to wait for the fabricators to get the steel columns built(Alot of gusset work and top and bottom plate). I'm working with some Commercial GC's and Steel framers that are used to ordering everything from the Fabricator on their million dollar projects and charging it back to the customer. I'm trying to figure this out myself.

There will be 3 steps, then a 8' x 6' raised platform, then another 7-8 step drop off the perpendicular end of the platform.

Many ways to do it.
Look through these then copy and paste url to pic and post on here.
Once we have an idea of what you want then we can go from there.
Can be as simple as box tubing on sides with steps welded to it to 1 central beam with steps off it to whatever.

I didnt see any that worked because of the 3" of material needed to make the riser. Picture making a stringer and riser with a 3" thick paving stone where only the top 1/2-3/4" can be exposed. This is my challenge.

I realize the 3" has to be incoprporated and figured into the 7 3/4 " riser height by code. But how, and how do you do it with a a front, back, and side lip? I thought of using 2.5 " angle iron all around the riser, but I still have to build the stringer.

I think this is what you want to do.

Why only 1/2" exposed? just design?

For the sides use box tubing, width and height and wall thickness to be determined. Weld your 2.5" angle on to it making a frame for the stone to sit in.
Will probably need an engineer stamp for approval.
Sorta like these, except tubing on both sides.

Get all the steel powder coated.

peakcelln 10-04-2012 07:41 PM

After 3 months, and ALOT of corrections, the Engineer finally completed the structural design of the basic deck and its gone thru permits. We were going to powder coat any steel that can be seen while standing away from the deck(Per HOA approval requirements), but one of the commercial guys said there's some paint that works almost as well at a fraction of the cost. Powder coating was $2/linear foot. I know its better, but It would have added another huge expense and time to the project. I really wanted to get the 10 fabricated columns alone, powder coated, but timing is really key now. I hope the paint looks somewhat good.

As far as the stairs are concerned, I don't know what box tubing is, but it sounds like steel track. I have a chop saw, just need to know how and where to make the cuts. Then I figure I'll use 6" studs for lateral support. I was thinking some kind of 36" grate might save me half of that 3" height problem on the riser, but I don't think it will be cheap.

Steel box tubing comes in many sizes.

Only cuts on it are the top and bottom angles., would have to miter the angle iron to make a box.

Thanx. I realized what I call Tube Steel is the same as Box Tubing. I used 3x3's to fabricate those columns. So youre suggesting a 8"-10" x 1" - 1 1/2" Stringer on both sides and weld my angle iron to it? I have not seen any tube steel that narrow. Whay wouldnt I use a 16 or 14 gauge 8-10" track piece on each side and weld to that? Seems it would save a bit of money.
