DIYHD Steel Stair Riser 4 Step Stair Stringer for Deck Height 35in

Solide

The stringers work as intended, nice and heavy and sturdy, however the inside bolt holes are difficult to work with. I didn't use any of the included hardware to attach the wood treads, instead I used bolts and nuts attached from the top-down, rather than screwing up through the treads. This worked well. The included hardware is good quality and I will save for some other project.

Good Product all in all, but holes could be placed better. Especially the most forward screw at the bottom step hole. That board has to be off in order to install the bottom rail anchor screws if you have any over hang on the sides. Even then the mount screw has to be pre-drilled and installed at a serious angle if you're anchoring to a wood surface at the very bottom. If the surface is concrete, you could drill and install it in the anchors in the concrete first. Then you would be okay. I expect 98% of the time, they would be mounted on concrete and work out better, but you're not going to be able to get the furnished screws in the step board leading edge hole because the holes are centered. If the holes were off to the side, you could, but even then it would be at an angle. That said. Use 2 X 12 step boards and you will be okay if you don't feel the need to use that hole. Since I was installing the stairs on a wood surface and using two 2 X 6's I already had Vs One 2 X 12's, I choose to use carriage bolts for the step boards. It turned into a lot of work pre-drilling the steps boards for the carriage bolts, but the end results worked out great. I am very happy with them otherwise and they are very sturdy.

Not used yet but looks good.

These seem to be sturdy enough, but the way they are designed, you have to screw in the step boards from below, and it is NOT easy to line them up and screw the screws in. But once that was accomplished, they seem to be working nicely.
