This is a sharp cornered mono stringer staircase. It is made from 2 pieces of custom-designed and cut steel plate to fit our purposes.
Now, everything we do is a one-off. This means we had to measure, design and build this staircase to suit the home from the ground up.
We welded the two metal plates together to make the box look like a giant set of saw teeth. We then welded in a 1/2 plate in the front and a 1/2 plate through the entire length of the stairs. To give you a sense of scale, that is about 12ft.
Both sides of the staircase are also welded together. Again, for scale, to create the sweet, sharp corners you see on the back, the project needed nearly 24ft of welding and 24ft of grinding.
The success of this design hinges on the precision of the cut pieces. In our experience, we believe this is one of the best ways to build a mono stinger staircase because it simply looks fantastic and provides a very accurate base to work from.
