These are the images of the stair case i built for Brad. The stairs are not completed at this time however brad has assured me that he will complete the necessary construction and fabricate the finish treads in a timely fashion. I used Google Sketchup to build a 3D model of the stairs prior to construction not only to convey the concept but also to reference clearances and dimensions. It worked great, With Brads help we measured, cut and bent the 8in by 3/16in stringer elements with each stringer taking two plates.
The tread bracket fits between the two plates and is welded in place level to provide a support for the tread.
In this design the treads provide a significant stiffening element. The steel itself is stiff on edge providing plenty of support but horizontally the stringers can flex.
The treads limit this flex by transferring the force on the circumference of the stringers and by creating a boxing effect between the stringers and the treads.
